The almost instantaneous load batteries and a shelf life close to eternity are taking shape. Thanks to quantum physics

by

Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology. During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose. The quantum storage of energy is an ideal that is increasingly closer The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass. Quantum batteries can store energy in a superposition of multiple energy states simultaneously It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density. In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being. So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.

close parks to lime and song

by

Madrid. July. The thermometer Nourish with the 38ºC. The heat is so suffocating, so sticky, that you just feel like sitting in front of a fan with a soda to the side and wait for the hours to spend. ESO or seek refuge under a tree of El Retiro or any other of the parks of the capital, vast green, leafy areas, full of vegetation and that after all are designed for that, right? The problem is that when you get to El Retiro you find that it is closed. Its closure in the middle of the extreme heat wave seems absurd, a “common sense” measure, like They denounce Some neighbors and politicians. The City Council alleges however that allows it to avoid misfortunes derived precisely from high temperatures. The big question is … Is that true? And compensates? When the heat comes … Madrid needs shadows. So much, in fact, that has invested 1.5 million In euros to install Quita and Put at Puerta del Sol to prevent the square from becoming a roast. When heat really arrives and mercury goes from 35º, what many neighbors do, however it is to seek refuge in the parks of the municipality, such as Whim, THE ROSALEDA OF THE PARK OF THE WEST, Juan Carlos i, Arias Torre, Watercress source And of course the good retreat, 125 hectares with leafy trees and a vividifying shadow. Click on the image to go to Tweet. Refreshing Park, Closed Park. The problem is that these parks are not always open. It happened yesterday, July 7when in some points of the community 35ºC were exceeded. Despite that heat, the risks that suppose and the need for shadow, the City Council announced The closure of El Retiro and other parks already in the afternoon due to “adverse weather conditions”. A quick review of the official account of the Consistory in X arrives to verify that it is not something exceptional: today nine green areas of the city (the withdrawal included) maintain some restricted parts, just like Sunday. Saturday Several grove directly closed their gates from three in the afternoon, just when the sun squeezes. Something similar had already happened on Wednesday. Some time ago The Spanish newspaper He made accounts and calculated that between May 21, 2021 and May 25, 2022 the parks were totally or partially closed 161 daysthat is, 44% of the days. Almost one in two. Europa Press esteem that since May the parks have closed about 10 times. But … why? By “adverse weather conditions”, emphasizes the City Council, which usually accompanies each notice of a link to The web in which it details the protocol that follows to close the parks of the city. Its logic is quite simple: the City Council uses a ‘traffic light’ of four colors (green, yellow, orange and red) that identify the conditions of the parks and to what extent they are suitable for the enjoyment of citizens if the risks are taken into account. To assign one or the other it is based on data provided by the AEMET. The technicians make the forecasts setting specifically in the situation of El Retiro and according to such different issues, the temperature, the water in the soil or the risk of storms. Hence The City Council emphasizesthat its calculations do not always coincide with the forecasts of other areas of the city. The most serious situation, the “red alert”, implies that all the planned activities are suspended, the enclosure is evicted and the park closes. And when is it declared? A priori when The technicians foresee wind gusts equal to or greater than 65 km/h with maximum temperatures below 35ºC and a percentage of water available in the soil of less than 75%. Another possibility (which is applied in summer) is that the streaks pass 55 km/h, but with high temperatures, in which the maximums are above 35º. When this alert is activated in the retirement, it is transferred to other large green areas of the municipality and the whim, Jardines de Sabatini, the Rosebed of the West Park, Juan Carlos I, Juan Pablo II, Quinta de Fuente del Berro, fifth of the mills and fifth Torre Torre Arias, green hectares, green. Reviewing the newspaper library. It may seem excessive, but the Consistory remembers that the retreat is full of large and old trees, “so they can suffer damage or fractures in branches and trunks.” In fact the protocol applied by the City Council Refers to that risk in your name. Your goal? Basically manage “incidents caused by trees.” It is not a minor issue. In March 2018 A four -year -old boy died due to the impact of a pine who collapsed in retirement, May 30 A 25 -year -old was critical of the fall of a branch in a Carabanchel park and does alone A few weeks A woman was seriously injured after a tree fell on her when she left home. Rain or snowfall involves a risk. The mixture of wind and extreme heat, also. “Against common sense”. That the closure of the parks respond to a protocol does not prevent the measure from generating criticism. Both neighbors (they are easily in networks) as of opposition parties. A frequent complaint and that I recently remembered The Europa Press agency is that the municipal protocol goes “against common sense”: if the heat waves are a threat and the parks serve among other things to mitigate it, why do they close just when they do the most missing? No other alternatives in the middle of the cannula? The issue has unleashed an intense debate at a social and political level. More Madrid He has insisted in which “a reflection on the review of the protocol” must be opened and update the inventory of the trees. And the Socialists have advocated “risk maps” that takes into account the type of woodland and avoid the complete closures of parks, in addition to direct access to the Eugenio Trías … Read more

25 years ago, Europe was close to panic at the barbarism of Japanese motorcycles. So Japan limited them to 299 km/h

by

The 90s were one of the golden times of motorcycling. A time when there was no Electronic controls, Anticontamination regulations No concern for security. Where now we see chaos and lack of control, a few years ago motorcycle manufacturers saw a test field to launch the fastest vehicles in the world. So much so, that the brands themselves had to put a limit to stop competing fiercely between them. What was happening. The motorcycle market has changed. Currently what is sold the most They are scooters and comfortable motorcyclesl, the SUV made motorcycle. In the 90s, the icons were the Japanese sports of Honda, Yamaha, Suzuki and Kawasaki. There came a point where virtually great street sports car reached vertigo speeds. In the early 90s, Honda launched her CBR900RR Firebladeone of the fastest production motorcycles in the world. It soon being overcome by the kawasaki ZZR1100 and later by the Hayabusa. A race to step on the grass of the neighbor that ended up uncontrolled. The 300 km/h. Motorcycles like Hayabusa ranly passed the 330 km/h, and in fear that governments imposed new regulations and prohibitions against such powerful vehicles, the industry decided to self -control with A gentlemen pact. The industry wanted to continue selling supercardives, but I did not want to intimidate the regulatory agencies with motorcycles that began to get closer to the barrier of the 400 km/h than to that of the 300. A secret pact. The gentlemen’s pact among motorcycle manufacturers is an open secret, although given the nature of the agreement there were never official statements. It is rumored that BMW began conversations with both Japanese and Italian manufacturers. Interestingly, when BMW did not have a single motorcycle capable of competing for being the fastest. Be that as it may, in the early 2000s the pact began to be fulfilled: the motorcycles launched by manufacturers, such as the Kawasaki ZZR1200 Or Honda’s proposals, did not exceed 299 km/h. But the sports market demanded speed and muscle, flying through the air the pact. It didn’t last long. Just seven years later, Italian as MV Agusta They left the pact in the air, with models such as the F4 R exceeding 300 km/h. It is something that BMW itself also did with its S1000R And, again, the fastest sports race began. Honda CBR1000RR-R-SP, much more than 299 km/h, although the scoreway says otherwise. What remains of the pact. Although there are numerous street motorcycles that exceed 300 km/h, the Japanese keep the pact alive. Manufacturers like Honda do not mark speed beyond 299 km/h, although the motorcycle is really running beyond her. The same happens with Yamaha. Versions such as the New Hayabusa or the Kawasaki H2, motorcycles that could touch the 400 km/h, remain electronically limited to 299 km/h. The Japanese respect and tradition keep the pact almost intact, maintaining the exceptions for circuit such as the Kawasaki H2R and its 400 km/h … with the house motorcycle. There are also those who dedicate themselves to prepare motorcycles to pass from 440 km/h. Luckily, they can’t step on the street. Not only in motorcycles. The pact among Japanese giants was not the only one decades ago. In the 80s and until well entered the 2000, manufacturers such as Nissan, Honda, Subaru and Toyota They signed a pact so that their cars had no more than 280 hp nor exceed 180 km/h. It is especially striking to upload a Japanese of almost 300 hp, and see that Your marker is tarado in those 180. The measure arose in response to the growing concerns for road safety in the country, an agreement not formalized before the public, but evident when analyzing car after car. This is still the limitations at 250 km/h in large part of current sports. Image | Austin Hervias In Xataka | Chinese motorcycles are sweeping in Spain: who is who in this brand puzzle

robots capable of intercepting any close object

by

Short. During a public talk at the University of Nankín, a researcher at the Chinese Academy of Sciences (CAS) He explained that they are designing A “fast response system” for the Tiangong Space Station. The active defense system, which has no precedents in the context of a space station, would deploy small propelled robots capable of grabbing and pushing any artifact that invades the station exclusion zone. How it works. The objective declared by the National Space Science Center is not to destroy, but to take away the intruder to protect the crew and its own infrastructure. Each tugboat would carry an autonomous propulsion system and an arm or fastening ring. Before launching a robot, the system would consider less aggressive options, such as an evasive maneuver or an altitude adjustment of the station. Only if the risk persisted, the device would be sent. After evaluating the path of the unauthorized visitor, a tugboat robot would anchor him and displace him a few kilometers outside the tiangong orbit. This does not go from space war. On July 1 and October 21, 2021, China had to perform emergency maneuvers to prevent the Tiangong Space Station collide with two satellites of the Starlink constellationwhich descended from an orbit of 550 km to 400 km, the usual altitude of Tiangong. Although SpaceX states that their satellites have automatic evasion protocols, China explained to the UN that the proliferation of large constellations “reduces the operational security margin” and makes real -time coordination difficult to protect its astronauts. Or yes? A Reuters analysis He described the Chinese initiative as a “first step towards possible orbital battles”, although he acknowledges that, if the non -lethal nature of the robots is confirmed, it would be physical deterrence rather than a weapon in its classic sense. Other countries already develop similar coupling and trailer systems to withdraw Large pieces of space garbagesuch as dead satellites, old rocket stages or damaged ships. The difference would lie in when and against whom these systems are used, taking into account The military escalation of space and The proliferation of spy ship. Does not violate space law. Although mass details, fuel or number of robots are confidential (such as the date of planned deployment), the outdoor space treaty only prohibits to place weapons of mass destruction in orbit: it does not veto conventional kinetic devices, or towing systems. If the robots limit themselves to pushing without damaging, they would fit into the principle of use for peaceful purposes. However, the potential to force the trajectory of the ship of another state can raise disputes on “harmful interference”, a concept collected in the same treaty. For now, we can leave it that China is preparing an active “orbital escort” system. Image | CSA In Xataka | Two years ago, the China Space Station did not exist.

AMD’s problem is not that it does not make good gpus for ia. Is that it is not even close to Nvidia

by

AMD is doing things well, but even doing them still unable to compete with Nvidia. The company has just raised its renewed road map with promising models, but that is not a guarantee of anything to a NVIDIA that will not let its absolute leadership position escape. The problem for AMD is not to be, but get others to take note. IDC consultancy data indicate that Nvidia dominates the AI ​​chips market with 85.2% market dick, for 14.3% AMD. Other analysts like Jon Pedie Research go beyond and According to your data The NVIDIA quota in this segment is 92%. AMD instinct mi350 are just the beginning. The GPUS for IA, which AMD calls “accelerators”, follow its evolution. During the event they presented their family or Instinct Mi350 series with two variants, MI350X and MI355X. According to the manufacturer, these chips are four times higher in general performance with respect to the previous generation, but are up to 35 times more powerful in the field of inference AI (that is, in the practical use of models such as Chatgpt, which “infers” “their responses from our prompts). They have 288 GB of HBM3E memory and a memory bandwidth of 8 TB/s. Its yield is 18.45 pflops in FP4 precision and 9.2 pflops in precision FP8. Instinct Mi400 in 2026. Next year the new family of AMD’s accelerators will arrive. It’s about future MI400 instinctwhich will arrive with up to 432 GB of HBM4 memory, 19.6 TB/s of bandwidth of that memory, and a performance of 40 pflops in precision FP4 and 20 Pflops in precision FP8. These monsters will be sold in future racks with infrastructure “Helios“, that You can house Up to 72 Mi400 with up to 260 TB/s total bandwidth thanks to its interconnection technology, Ultra Accelerator Link. EPYC VENICE. AMD not only talked about GPUS: it also has its future processors for servers in data centers in full development. The Epyc Venice will arrive in 2026 and will be based on Zen 6 architecture. Among the variants, an especially spectacular with 256 cores that will offer up to 70% more performance compared to the previous generation. These processors will be built with future MI400 instinct. They are expected to be manufactured with the N2P (2 Nm) node of TSMC. Helios against Oberon. The aforementioned Rack Helios will compete with not already with the current Nvidia AI server, the GB200 NVL72 which connects 36 CPUS Grace and 72 Gpus Blackwell. He is destined to compete with his successor, which has Oberon’s code name and will use IA B300 GPUS with Vera Rubin architecture. The yields and benefits of these future racks are absolutely dizzy, and for example their Precision Power FP8 is 1.4 Exaflops. The same in some things, better in others. AMD promises to match NVIDIA in several sections, but also ensures that it will exceed it remarkably (50% more) in memory quantity and width, something crucial for training and inference AI. Be careful, because at the end of 2027 NVIDIA prepares the Rubin Ultra architecture, which promises racks with up to 5 Exaflops in FP8 precision, three times more than Helios or Oberon. In 2027 we will have another “summer”. The AMD roadmap goes further, and they have already prepared the development of their new generation of chips for summer Epyc servers, which will replace the Epyc Venice. These CPUS will be paired with the future MI500X instinct, and it is expected – although it is not safe – that both types of chip take advantage of the one already announced TSMC A16 node (1.6 Nm), which will begin to be used at the end of 2026. There are no specifications for these developments, surely because they will depend on the manufacturing node that AMD ends up using to produce them. Frantic race. All these ads show that AMD does not want to be left behind in that race to place their solutions in data centers worldwide. The Crusoe company, which is dedicated to the construction of large AI data centers, advertisement A few days ago I would spend 400 million dollars in AMD’s chips, and even Sam Altman, CEO of OpenAi, made a surprise appearance During the inaugural talk of the Lisa Su, CEO of AMD event. Altman said they will also use AMD chips in the data centers they use, and highlighted that the new AMD ia gpus “will be somewhat amazing.” AMD presumes to be more efficient (and cheap). AMD’s message was clear during the event: its MI355 offer much more efficiency and are cheaper than NVIDIA B200 and GB200 with comparable yields. The sales prices of those GPUS are not known, but we do know that at the beginning of 2024 the MI300x of AMD They cost a maximum of $ 15,000 for the more than $ 40,000 that cost The NVIDIA H100. The biggest challenge is still CUDA. The benefits of AMD AI chips are not in fact the problem of this company. Detailed studies revealed months ago that MI300X are clearly higher than NVIDIA H100 and H200 on performance and power. However, Nvidia has a Cudathe de facto standard in the industry for services of services and applications of AI. Using AMD native software is feasible, yes, but software experience, They assured in SEMIANALYSIS“Software is full of errors that make training (AI models) with AMD it is impossible.” AMD’s hope is Rocm. In that AMD event also presented Rocm 7, the latest version from your own Open Source programming platform for your GPUS. In AMD they indicated that this version is 3.5 times more powerful than Rocm 6, and even claim that it is 30% more powerful than CUDA in the B200 when serving the model Deepseek R1. Even so, they indicate In another report of semi -health, it is still lower in some sections. Getting that component allows developers to take advantage of all the potential of AMD’s chips is precisely key to the future of those efforts. Even … Read more

China has been so close to dying with its solar panels that has made the only logical decision: manufacture less

by

China is a colossus in the photovoltaic industry segment. They are not just installing huge parksbut dominate production with iron. So much that they have made The whole world depends on its technology and collapsed the price of the panels, drowning European and American manufacturers. The result of the crazy expansion was An internal price warbut after years of losses in the domestic market, they already propose a solution. Manufacture fewer panels. Storm. In 2020, China presented a zero emission plan Net for 2060. The goal is reduce your considerable carbon footprint and pollution and, for this, They marked That in 2030 there should be at least 1,200 GW of solar and wind capacity installed. The energy began to act, but companies from other sectors saw that there was a lucrative opportunity and got into the business. The result? Market saturation and such a beast production of the modules that were drowning foreign companies, but also to the domestic market. If 1,200 GW of renewables installed in 2030 were needed, only the solar installed in 2024 already surpassed The 880 GW. To the search for solutions. Production folded world demand And prices crashed, with huge companies in the sector asking the State for help To be able to continue in business. In that unsustainable situation for your own industry because They lost money with each salea kind of OPEC For Chinese photovoltaic, the Chinese photovoltaic industry association, or CPPO, with 33 of the main manufacturers signing a self -control commitment. The meeting was held in December last year and its executives are still looking for solutions after years of price wars. This week the Snec pv & is expo 2025 In Shanghai, in which manufacturers and companies around the world have met to evaluate the global situation. And, although we have to wait to see what measures they take, the Asian association of the photovoltaic industry – one of the organizers of the event – is clear that it cannot be followed in this situation. Or we refer to one or sink. As we read in South China Morning Post“The solar industry is not a zero -sum game,” said Zhu Gongshan, president of the association, in the inauguration speech. “We are in this together and the extreme cost of costs and fierce competition are not different from drinking poison to calm thirst,” he said. China installed About 278 GW of solar capacity last year, a figure that represents almost 60% of the new facilities worldwide. And it was the result of an overcapacity that contributed to a fall of 60% of the prices of the solar modules between 2020 and 2024. At the December meeting, one of the measures agreed by the main manufacturers was to respect a minimum recommended price to preserve the margins, and had a moderately positive result in early 2025, with a price rebound. But they don’t loosen the accelerator. The Cpia estimated Between 215 and 255 GW for this year, a cut in front of the amount of last year, but the accounts do not leave and the rhythm of facilities that are being kept is still very high: until April 30, 105 GW had been added, 75% more than what was installed in the same period of the previous year. It is estimated that it was because in January a large number of facilities were carried out and that they will fall 44% in the second half of 2025. One of the measures driven By the Government to reorganize the industry, it entered into force on June 1: sell production at market price instead of a guaranteed rate in the new solar plants. The antidote. “Instead of waiting for a cyclical recovery, we must face a disruptive restructuring in the sector,” said Zhu. And what are the proposals? Several are handled, such as focusing on improving collaboration between the government and companies to confront the offer through regulations or mergers. Another is that I know Bet on technological innovation for both panels and production chain, which will allow sustainable growth and higher benefit margins. That is, not to make the crazy panels that anchored to a technology that can be quickly outdated, but is cheap, but to improve quality and make fewer panels, maintaining a higher price and avoiding saturation. Change of mentality. Another problem is that there are too many things to consider. Those 33 Chinese companies of the CPPO are not the only ones that manufacture panels and there are those who may not respect self -control agreements. But, in addition, these internal problems are added tariff manids imposed by the United States. In the case of panels, Trump’s administration He imposed tariffs of More than 3,500% to the importation of panels from China and 60% to materials such as polisilicio, wafers and Chinese solar cells. China’s response, according to the president of one of the local businesses, should be internationalization. “Due to tariffs, it is no longer enough to export: we must locate production abroad,” said Gao Jifan, president of Trina Solar. We will see what happens, but try to stop that saturation of the market is significant, and that they talk about democrating production can generate a new battle from Western countries that we have already seen with the Chinese car: the one that try to attract the attention of manufacturers.

A US nuclear power plant was going to close after running out of subsidies. Mark Zuckerberg has taken the opportunity to keep it

by

Training large models of artificial intelligence consumes so much energy that technology companies are “appropriate” of nuclear power plants. Goal saves a nuclear power plant. Goal, the Facebook, Instagram and WhatsApp matrix, He has just signed an agreement which symbolizes paradigm shift. The company led by Mark Zuckerberg has saved a nuclear power plant that had the days of a 20 -year contract. Constellation Energy Corp., the largest nuclear operator in the United States, will supply 1,121 megawatts of energy from its Central de Clinton, in Illinois, directly to the target data centers. The contract will begin in mid -2027 and will be in force until 2047. It is not a casual date. 2027 is when the state subsidy that kept the Clinton nuclear power plant. To understand it you have to rewind 10 years until 2017. At that time, the Clinton Power Station, like so many other nuclear centrals in the US, was on the tightrope. Unable to compete with the low prices of natural gas and the rise of renewables, its then owner, Exelon, threatened to close it. Only an intervention in extremis From the Illinois government, which approved a 10 -year subsidies package, the oxygen ball it needed. A Big Tech knocked on the door. Finally, it will be a technological giant, in full boom of generative artificial intelligence, which stays with the Illinois Central. Total goal consumption It has been quasite Between 2019 and 2023. Training and operating generative AI models requires giant data centers running at full performance 24 hours a day. This is where the main weakness of renewable energy sources is shown, such as photovoltaic or wind solar: despite being a key piece of the stark strategy of technology companies, their intermittency makes them an insufficient option. Nuclear energy, with a massive and stable supply, complete the puzzle allowing companies to maintain their commitments to be neutral in carbon emissions. Goal is not alone. The goal is the last one, but it is not an isolated case. Rather, it is the confirmation of a strategic trend that has been consolidated in the last two years. Technological giants have gone from signing energy purchase agreements with renewables to actively seek the stability of atomic energy. In a movement similar to Microsoft, Microsoft signed an agreement with Constellation for Reactivate Reactor 1 of the Three Mile Island Central (famous for the accident of your reactor 2). The Central, which had been closed in 2019, now feeds the Azure data centers for AI. Amazon Web Services has moved directly to a nuclear power plant. In March 2024 bought for 650 million dollars A gigantic data center adjacent to the Susquehanna plant, in Pennsylvania. The agreement guarantees 960 MW of direct energy for its AI operations.

The first quantum computer with error correction already has date. It is close and will be 20,000 times more powerful than the current

by

It seems that in the end Israeli mathematician Gil Kalai was wrong. This professor at Yale University has been very critical for several years with Quantum computing. In fact, he argues that the increase in the number of states of quantum systems and their complexity will cause They end up behaving like classic computersso the superiority of the former will end up evaporating. It defends, in short, that totally functional quantum computers They will never arrive. However, we currently have very solid reasons to anticipate otherwise. And there are several companies that ensure that they will have a quantum machine equipped with the ability to amend your own mistakes Before I expire this decade. These computers will be very important because they will presumably have the ability to solve a very wide range of problems with which not even the most powerful classic supercomdators available can deal. Just a week ago we told you that Xanadu, a young Canadian company founded in 2016, Plan to have ready before 2030 A quantum computer of one million phototonic ulna with error correction. However, it is not the only company that intends to make this milestone come true. IBM plans to make available to its customers in 2029 ‘Starling’, its first large -scale quantum computer equipped with the ability to amend their own mistakes. It will execute 20,000 times more operations than current quantum computers IBM is going to build The quantum computer ‘Starling’ in a new data center that will be housed in Paughkeepsie, New York (USA). This machine will bring together 200 logical cubits that, in theory, will allow you to execute 100 million quantum operations. Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical ul Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows detect and correct errors that are present in physical cubits. Until very recently the number of hardware cubits that was necessary to implement a single logical cubit immune to errors was impracticable, but IBM says it has found the solution to this problem. Their engineers have published two very interesting technical articles in which they develop the strategy they will use to bring to fruition their large -scale quantum computer and error correction. In the first These articles explain what procedure will continue to process instructions and execute operations in an efficient way. AND In the second They describe how they will decode the information that physical cubits contain in an efficient way, and also what strategy they will use to identify and correct real -time errors using conventional computational resources. As I mentioned a few lines above, IBM says that ‘Starling’ will be ready in 2029, but before its arrival this company expects to reach other important milestones. At the end of 2025 ‘Quantum Loon’ will prove the technology used to connect cubits to a larger distance Within a single chip. In 2026 ‘Kookaburra’ it will be the first IBM modular processor designed to store and process coded information. In 2027 ‘Cockatoo’ will arrive to demonstrate that it is possible to intertwine two ‘Kookaburra’ modules, and, consequently, that it is viable to connect several quantum chips such as nodes of a larger platform. And finally, after ‘Starling’ will arrive ‘Blue Jay’, which will bring together 2,000 logical cubits that, in theory, will allow you to execute 1 billion quantum operations.

Inditex has discovered that its giant stores are less and less profitable. The problem is that you can’t close them

by

Barclays has put his finger on the sore of the Inditex business model. His analysts question whether the megatiendas of the textile giant can continue to generate the productivity improvements that have promoted their growth during the last decade, according to Five days. The origin of the doubts is in its weak growth of the start of the fiscal year, which has slowed that until now it was a strong and almost uninterrupted growth. What has happened. Between 2019 and 2024, Inditex has increased its sales by 37% despite reducing the number of stores by 29%. The average size of its establishments grew 23% to 836 square meters, but sales growth is deflated: 11% in March 2024 to 4% in March this year. Why is it important. The figures show an uncomfortable paradox: While online sales grow with higher margins and minor costs … … physical megatiendas devour resources and generate decreasing profitability. However, closing those megatiendas, in emblematic or high visibility locations, with very high costs that eat a good part of the margin, could be counterproductive. The context. The Inditex megatiendas They are not just stores: they are Showrooms strategic Its real function goes beyond maximizing sales per square meter, they also serve to legitimize online prices. A jacket of 80 euros on the Zara website seems reasonable because the customer can touch it, try it and validate its quality in a store, especially in a 1,000 square meters in the center of Madrid or Barcelona. And because of the fact that this brand is there, conquering that space. In detail. The model works like this: Megatiendas create the perception of premium brand that justifies online prices. It is not something that has invented Inditex or exclusive to fashion stores. McKinsey already talked about this phenomenon Before pandemic. Without that physical presence, Zara would lose some reputational credibility in the face of much cheaper purely digital competitors such as Shein. Physical spaces act as confidence anchors that allow to collect higher prices on the digital channel. Yes, but. The equation is complicated when the profitability of these Showrooms It deteriorates. Barclays estimates that the growth of sales per square meter will decelerate 8% historical annual to 3% in the next four years. Maintaining very expensive spaces that do not generate proportional direct benefits is a bit more difficult to sustain in the long term. Turning point. Inditex will possibly redefine your megatiendas without loading your strategic value. Closed would save costs but destroy a part of the credibility that supports online prices. Keep them as the margins are erodes. The departure is to reinvent them as brand theaters that justify their cost through their impact on the digital business. It is something very similar to what happens with telecos stores, especially Flagship: They maintain strategic establishments in central and privileged locations for a more reputational and Awareness (Brand recognition, perception, prestige) that by pure profitability.

Barajas airport has become the “home” of 500 people. If you want to solve it, it has a close example: the Prat

by

There are 421 people, most live in terminal 4 of the Adolfo Suárez Madrid-Barajas airport. More than half are registered in Madrid and almost four out of ten say they have a job. This is the radiography of the Syntch that inhabit the largest airport in Spain. The data exposes them The country who has had access to an internal document of AENA in which the situation in which the hundreds of people who night night after night In their facilities and that have attracted the focus of today in recent days and weeks but also, unintentionally, they have become a policy throwing weapon between administrations. The ASAE union data (Aena Enaire union alternative) raised the figure to half a thousand people in February. According to your calculations, 500 people were exceeded Those who spent the night at the airport. For days, local, regional and state administrations indicate on the contrary as the cause of the situation in which hundreds of homeless who are calculated that they live in the airport. Some and others They are pointed out as guilty of not finding a solution to the problem. And on the debate of the Madrid airport floats the shadow of what was lived in Barcelona. El Prat airport has been found in the same situation for years and gradually the homeless number living in these facilities has been reduced although always taking into account that specific rebounds occur. This is how administrations have worked. Coordination to reduce the problem Although Madrid and Barcelona They are not the only airports Where this situation occurs, the Catalan airport is known for having launched various performances over the years to try to alleviate the problem. In one of the last counts 108 people were counted living in him El Prat Airport. As in Madrid, some of them spend the day at the facilities while others leave during the day and return at night to shelter from the cold. The situation, however, seems to have improved in recent years although measures have been taken for more than a decade. In Europa Press They point out that the first time it was acted to reduce the non -roof number at the airport was in 2011 when the “then Department of Social Welfare and families constituted a working group with the Barcelona City Council that initiated the social intervention and accompaniment at the El Prat airport.” The situation remained stable but in 2022 the problems returned and the game of competencies and administrations began. The avant -garde He explained in a report that a non -counted number of people lived in one of the airport parking lots, which was being renovated. The voices that expressed themselves in the report made it clear that the administrations had turned their backs. And that year, in 2022, the Generalitat stopped financing these assistance teams and in 2023 the Barcelona City Council did. Then it was alleged that the Consistory of the city of Condal did not have the Competencies To act at the airport. In 2024 no administration did his job at the AENA facilities. That neglect, they point out in Europa Press It caused a rebound in the people who did life. At the end of 2023, 177 homeless people were counted. It has not been until 2025 when the administrations have launched an operation to reduce the without roof number at the airport facilities and have tried to redirect them to the Social Services circuit. That social services circuit depends on the municipalities. Lluís Torrens, who was Secretary of Social Affairs and Families of the Generalitathe has assured The country that the competitions are very clear and that giving support to homeless people is the responsibility of the municipalities. In the Prat, the City Council of Barcelona and that of El Prat had to coordinate to give a way out to these people since the emergency services of El Prat could not support due to lack of means. There, Aena and the municipalities managed to clarify the powers with the intervention of the Generalitat. Torrens, responsible for the actions, defends that it is the consistors who have to put the means but that if necessary the Regional Administrations They are the ones that have to intervene to coordinate the efforts and even provide economic resources to the municipalities if they do not have the necessary means or facilities to absorb people who leave the airport. As for Aena, in February a first drill was launched to try to accompany the homeless people to the social services circuit and try to shelter them outside the airport. It was AENA’s security employees who, together with the police, asked the homeless to leave the facilities. In a joint work, they were explained that they would have to leave the facilities to clean the environment. In Diari ara The march of these people was narrated. In the eviction no confrontation was detected but these people were explained that they could not re -enter the facilities if it was not with a boarding card to take a plane. The device remained a few days and since then groups of social teams are maintained to serve these people. Since then, the without roof number spent at the airport has been reduced to about 50 individuals. At the moment, in Madrid Aena has made the same decision to ask for the boarding card to those who try to access the airport but are only being carried out in the lower intensity time. That is, at night. The Madrid City Council has described this decision as A “patch”. Manuela Bergerot, spokesman for more Madrid in the opposition, points out the measure as “an arbitrary prohibition to people who do not have a boarding card to be able to pass to the airport or who do not seem companions. It is the entrance door to institutional racism.” From the Community of Madrid they point out as main guilty To Aena and the central government. “The … Read more
