review with features, price and specifications

I think that, as a reader in general and a manga lover in particular, I have found the gift that I will put this year in the letter to the Three Wise Men. Each and every one of the gadgets that I have tried to read digitally They have given me some problems: either they are small, or their screens tire my eyes, or they distract me with notifications or they do not easily accept the most common formats. He Boox Go 10.3 (Gen II) Lumi It’s quite the opposite. It is what, as a reader, I would definitely want to have on my nightstand and in my backpack. The only thing I’m missing is the 450 euros that, unfortunately for my pocket, it costs. ✅ Buy it if… You read a lot in digital. You want a comfortable, large e-book reader with a good battery. You don’t like the idea of ​​having to buy all the books on Amazon Kindle. ❌ Don’t buy it if… You tend to read unusually or sporadically. You don’t want to spend a lot of money. You want a color screen. The essentials in 30 seconds The Boox Go 10.3 (Gen II) Lumi is a book reader with a 10.3-inch black and white e-ink display. Everything is normal, except for the operating system, which is Android 15. What does that mean? That you have access to Google Play and, therefore, to the entire ecosystem of reading apps (and non-readable) available for Android. It doesn’t tie you to a platform (like Kindles), but rather gives you total freedom. It works sensationally, it supports all home formats (PDF, EPUB, CBR, MOBI, doc, docx…), it has a backlight (it’s the difference between the Lumi model and the standard one) and the pen is very useful. Your main problem? That it does not have a color screen, that it has little capacity and that the price to pay for it is quite high. Now, if you do not intend to read color documents and are looking for a good black and white reading device for books and manga, this is, without a doubt, one of the options to consider. BOOX Go 10.3 Gen2 Lumi Epapel Tablet 10.3″ Monochrome Front Light 300 DPI 64 GB Android 15 E-Ink The price could vary. We earn commission from these links Our experience with the Boox Go 10.3 (Gen II) Lumi Boox Go 10.3 (Gen II) Lumi | Image: Xataka E-ink display: pros. If we talk about reading for a long time, electronic ink screens have no rival: they tire the eyes much lessthey have less reflections and do not suffer when placed in broad daylight. This device features a 10.3-inch eInk panel with 300 pixels per inch resolution and, simply put, it looks great. Not only is the text crisp, but the manga drawings and fine panel details look spectacular. I have not had the slightest problem when reading books, manga, websites and even working with PDFs. A note about qualities: the device offers us several screen configurations, so we can choose if we want a faster refresh at the cost of losing sharpness, or more sharpness at the expense of losing transition speed. Here to taste. I have used it most of the time with the second configuration. Big, but comfortable. It is a large device, but very thin and weighs 300 grams. This means that we can carry it in our backpack without it getting in the way (it came with me to Poland, in fact) or that we can use it in bed without our arms getting tired. In fact, it’s funny that the pencil, which we’ll talk about shortly, is thicker than the reader itself. The weight seems more than it is, in practice it doesn’t feel like it weighs a third of a kilo. Boox Go 10.3 (Gen II) Lumi | Image: Xataka Moves in fear. Although its specifications may seem modest, the truth is that Android 15 works well with the four gigabytes of RAM and the Snapdragon 750G processor that it has. The 64 GB of storage, however, seems somewhat scarce to me and, furthermore, they are not expandable. By default, there is certain ghosting when we turn the page, but it is neither very exaggerated nor is it something that cannot be fixed by adjusting the refresh rate. I have it configured so that the screen refreshes completely when turning five pages, but if having the shadow of the page is a nuisance it can be adjusted so that it refreshes when turning one. This, needless to say, will slow down loading. Android is always a good idea. The interface is well adapted and has everything necessary to work, namely a reading app compatible with all formats, a browser, an AI assistant whose presence is testimonial, and Google Play. The advantage, of course, is the compatibility with Android apps, so you can install Google Play Books, Kindle, Moon Reader, Notion or Manga Plus to stay up to date with One Piece. It supports all popular formats, so you can use any EPUB, MOBI or PDFs you buy on any platform. About the pencil: the device includes a stylus to take notes, write, make annotations on files, etc. It works quite well and responds to pressure, but there is minimal latency that makes typing feel a bit clunky. It makes more sense to make specific annotations on a PDF or a drawing than to take quick notes in a class, for example. Boox Go 10.3 (Gen II) Lumi | Image: Xataka Charger? The device arrived charged at 80% 16 days ago and today, after using it literally every day for at least an hour-hour and a half, I put it on charge with 28% battery remaining. This is the advantage of these devices: they barely consume anything. Loading is a little slow, but nothing to worry about considering that we will do it every so often.

Spain is committed to connecting Madrid and Barcelona at 350 km/h. And you have already taken the first step to achieve it

Madrid and Barcelona linked by a train capable of reaching 350 km/h. Just when the journey between the two largest Spanish cities has become a Russian roulette if your goal is to arrive on time. And just where the Renfe trains are having the most problems fulfilling what is expected. However, the Government is determined to increase the maximum speed of the line. And you have already taken the first step. At 350 km/h. In November 2025Óscar Puente, Minister of Transport, presented one of his star projects: linking Madrid and Barcelona with a train that travels at a maximum of 350 km/h. The final objective is to be able to travel between both cities in less than 120 minutes when it is now necessary to spend at least 182 minutes. As long as everything works correctly, of course. To reduce the trip by one hour two interventions are necessary for which the necessary papers have already begun to be moved. One of them is the construction of two new stations, one in Parla (close to Madrid) and another in El Prat de Llobregat (close to Barcelona). The objective is to decongest the traffic that currently passes through Madrid and offer a variant of exit and entry to Barcelona. The other intervention would be applied to the infrastructure itself and, it seems, will be the first to be carried out. A first step. The Ministry of Transport has confirmed which has already awarded a first supply batch of overhead traverses for the Madrid-Barcelona high-speed line. A 112 million euro contract that is key for trains to reach 350 km/h top speed. These first air traverses will be installed in four sections: Mejorada del Campo-Brihuega (232,400 units), Brihuega-Alcolea (143,150 units), Alcolea-Ariza (166,250 units) and Ariza-Calatayud (138,600 units). In addition, some maintenance tasks have been awarded “such as the renewal of the seat plates for sleepers (elements that ensure the fixing of the rail to the sleeper).” Finally, the Ministry of Transport points out that “treatment and improvement actions are being carried out on two viaducts on the Guadalajara-Calatayud section of the Madrid-Barcelona high-speed rail line, Benamira and Río Blanco, both in the province of Soria.” A physical question When the train exceeds 300 km/hthe aerodynamic load on the underside of the trains increases. This load is generated by turbulence under the train car, “gluing” it to the track. The more load, the more energy the train has to use to maintain speed. If the train releases that aerodynamic load a little, it does not need as much energy and it is easier for it to reach the desired top speed. It is the same case as a Formula 1. The car is interested in having a lot of downforce on a circuit with many curves because it will be able to go through them faster. However, it will penalize on the straight because the top speed will be lower. On the contrary, if the circuit has few corners and many long straights, you are interested in low downforce to “fly” as fast as possible. But the car will be more unstable when cornering. Furthermore, the Ministry of Transport explains that the ‘ballast flight’ must be added. This is the vibration of the stones, the ballast, when the train exceeds 300 km/h. At that speed it is critical because the turbulence raises these stones and produces constant collisions against the undercarriage and increases the risk of them being thrown and falling on the tracks and sleepers, generating potholes and vibrations. The air traverses. Since the project was presented, the Ministry of Transport has indicated that the aerocrosses are key to being able to guarantee speeds greater than 300 km/h on the route. But, What are aerocrosses? The aerocrosses are born from an Adif project which has been working on for more than a decade. Its design is very similar to current sleepers at first glance, but it has a rounded design that reduces the turbulence generated under the trains and, with it, the pressures that increase the aerodynamic load and ballast flight. According to his calculations: Reduces the aerodynamic load in the space immediately above the ballast bed by 21%. The design allows increasing the distance between the ballast level and the upper face of the sleeper. It has no higher manufacturing or handling costs (they are still molds). And most importantly: the aerodynamic load generated by a train at 330 km/h on a track with current sleepers is equivalent to that generated by the same train at 370 km/h, but with aero sleepers. In a delicate moment. He Adamuz accident in Córdoba led to the machinists to lift their foot on the line and Adif ended up lifting temporary restrictions of speed that have been happening until today while the line is being reviewed. The result is that Madrid-Barcelona will be played in the promised 182 minutes (25 minutes more than usual) is, right now, taking a chance. This has caused a good part of the passengers who used the train to travel during their work day, with many comings and goings during the day, to move back to the Aerial Bridge. The CNMC calculates that up to half a million passengers may be lost if travel times remain higher than usual. But, in addition, the Madrid-Barcelona line is where Renfe has detected the most problems with its Avrils. The vibrations on this route ended up generating cracks in the Talgo trains, designed to be used on variable gauge trackwhich gives them a competitive advantage in Madrid-Galicia. However, Renfe had to remove them from circulation upon seeing that they broke on this route that is now being renewed.

First it was a suspicious cake. Now China has discovered that thousands of restaurants on its delivery apps… do not exist

One of the most famous stories of the internet era it happened in 2013when American journalists discovered that a supposed restaurant called “The Shed at Dulwich” became one of the best rated of London despite the fact that, for much of its existence, it did not even serve real food. The case demonstrated how a compelling digital presence can be more powerful than an authentic physical business. The cake that uncovered the cake. It all started with something seemingly trivial. A customer from Beijing ordered a birthday cake through a delivery application and received a decorated product with inedible flowers. The claim seemed like just another incident among millions of daily orders, but the subsequent investigation ended up uncovering one of the largest food fraud schemes in Chinese digital commerce. The business he had purchased from claimed to have nearly 380 stores spread across the country. Actually, I didn’t have not a single physical store. The licenses were fake and the company existed only within the applications. What started as an isolated complaint ended up opening the door to a national review that revealed a much deeper problem: “ghost kitchens,” thousands of restaurants that seemed real to consumers. They just didn’t exist.. Food delivery drivers start their workday for Kangaroo delivery service in Beijing The operation. Apparently, the BBC told this week that the so-called “ghost kitchens” were operating by taking advantage of the control gaps of the delivery platforms. These businesses advertised themselves as conventional restaurants, often using rented licenses, falsified documentation, or non-existent addresses. When a customer placed an order, the supposed restaurant I didn’t cook anything. In many cases the order was automatically transferred to intermediary platforms that organized auctions between different suppliers. The order ended up in the hands of whoever agreed to prepare it. for the lowest price possible. The consumer believed they were buying from a specific brand when, in reality, the food could come from any unknown kitchen, without knowing who made it or under what sanitary conditions. The figures of a monster. The national investigation carried out by the Chinese authorities revealed the magnitude of the phenomenon. Inspectors identified more of 67,000 ghost restaurants distributed among the main delivery applications in the country. In addition, they discovered a chain of illegal orders that only in the cake sector had been managed around of 3.6 million orders. The authorities they concluded that delivery platforms, middlemen and numerous sellers had built a parallel supply chain based on opacity and in mass subcontracting. What seemed like a set of isolated frauds turned out to be an industrialized system that operated on a large scale and moved millions of transactions. The price war behind the fraud. They remembered in Nikkei that the origin of the problem lies in the fierce competition in the home delivery sector in China. With almost 630 million users Using these services, platforms compete to attract customers through constant discounts, aggressive promotions and an ever-increasing range of establishments. In that context, the pressure to reduce costs It ended up generating a race to the bottom. An example cited by the investigations showed how a cake sold to the customer for $35 ended up being awarded to a supplier willing to manufacture it. for just 11 dollars. Between intermediaries, commissions and platforms, much of the money disappeared before reaching the chef who actually prepared the product. The consequence was a model that rewarded volume and price above quality, traceability and food safety. The platforms, in the garlic. The investigation was not limited to the sellers. The authorities they concluded that many platforms had deliberately relaxed their controls to accelerate their growth. According to regulators, companies they did not properly verify the licenses of the establishments and allowed the presence of unauthorized sellers because a broader offer helped to attract more users. Some employees they came to recognize that applying strict controls could cause merchants to migrate to rival applications. The result was a situation in which commercial incentives ended up trumping legal and health obligations. Historical fines. Beijing’s response has been one of the most forceful seen in years within the Chinese digital economy. The authorities imposed sanctions worth 3.6 billion yuanabout 500 million dollars, to large companies such as Taobao, JD.com, Meituan, Pinduoduo, Douyin and other platforms involved. Some businesses were temporarily suspended from recruiting new vendors and forced to eliminate detected ghost restaurants. Sector analysts have described the operation as one of the tougher regulatory sanctions imposed on internet companies since the entry into force of the current food legislation. The new digital surveillance. From now on, platforms must verify periodically that the licenses are valid, that the physical addresses exist and that the businesses actually correspond to the advertised establishments. Restaurants without in-person service will have to state it clearly to users. At the same time, some cities have begun to implement transparent kitchens equipped with cameras that allow you to follow the preparation of food live. They are also being deployed artificial intelligence systems capable of detecting fake photographs, supervising kitchens and analyzing possible irregularities. Even delivery drivers have been incorporated into the surveillance system through reward programs for those who report suspicious establishments. The end of uncontrolled expansion. Beyond food safety, the campaign reflects a broader shift in Chinese regulatory strategy. For years, platforms grew by prioritizing the number of users, sellers and orders. Now Beijing wants to replace this accelerated expansion with a model more controlled and predictable. The appearance of tens of thousands of non-existent restaurants showed the extent to which competition had distorted the market. What began with a simple cake purchased online ended up revealing an ecosystem where millions of consumers believed they were choosing between thousands of different restaurants when, in many cases, behind the screen there was no establishment, no dining room and, sometimes, not even a real company.

We are in 2026, but you will only see part of the World Cup in 4K because of DAZN: TV manufacturers are already rubbing their hands

You have a 4K TV, you have contracted Movistar Plus, Orange TV or DAZN and you are ready to live the Soccer World Cup 2026 in the best possible quality so as not to miss any details. Well we have bad news for you: almost all the games will arrive on your screen with a 1080i resolution, even if your television platform can broadcast in 4K. The fuse was lit as a result of the message from a user from Movistar Plus on X, in which he asked if he could watch the World Cup in 4K HDR. The initial response from Movistar was “Yes, as long as you have the UHD disc you can watch the games that will be broadcast on DAZN in 4K HDR.” The problem is that, when asked by our colleagues Xataka Mobileboth Movistar Plus and Orange TV have discarded that those matches are going to be broadcast in 4K. The controversy is served. The World Cup signal comes in 1080i: that changes everything DAZN is the one who has the rights to broadcast the 104 matches of the tournament in Spain. The problem is that your DAZN World signal arrives in 1080i resolution, not 4K. Since Movistar Plus and Orange TV only limit themselves to distributing the signal, what they receive is what they give you. Both operators have confirmed it: there will be no 4K on their platforms for the World Cup matches. In Xataka The gap between Samsung and TCL in the television market seemed unbridgeable. Until it stops looking like it This represents a clear setback in terms of resolution and image quality since in Qatar 2022, World Goal It broadcast the 64 matches of the championship in 4K UHD both on Movistar Plus and on its own app. However, all is not lost. In a corner of the reviled DTT we have a glimmer of hope left for those of us who want to see the World Cup in the USA, Mexico and Canada with the best possible quality: La 1 UHD (Ultra High Definition). Yes, on DTT RTVE took over the rights to World Cup broadcast and will offer 33 open matches, including the opening match, the two semi-finals, the third and fourth place and the grand final, in addition to all the matches in which the Spanish National Team participates. These 33 matches will be the only ones that can be seen openly and in 4K in Spain. However, this RTVE signal also has small print for television platforms such as Movistar Plus and Orange TV, since on its grid They carry La 1 HD, but not La 1 UHDso to watch the games in 4K it will be necessary to tune in to the La 1 UHD channel on DTT, not the platform. First impressions of the TCL RM9L with RGB MiniLED: the alternative to OLED for large format screens Only Vodafone TV customers, you just added the RTVE channel in 4K on your grill, and Digi TV They will be able to watch the matches broadcast by the public entity in 4K quality from their platform. In short: if you want the 33 games in 4K, you need DTT (free to air) or Vodafone TV and DigiTV (with subscription). If you want to see the rest, you’ll have to settle for 1080i resolution. All is not lost: your television can save the game This is where something that few people take into account comes into play. when buying a TV: he image processor and its algorithms image enhancement and scaling. No matter how good your TV is, it’s not going to convert a 1080i resolution signal into 4K by magicbut it can improve a lot quality in which you watch the World Cup. Current televisions apply a process called upscaling, in which they take the input signal and upscale it to the panel’s native 4K resolution by adding, through AI and other algorithms, data that was not in the original source. In fact, it is the same process used by 8K TVs to display content that is in 4K. {“videoId”:”x95se90″,”autoplay”:false,”title”:”How technology has changed football ⚽️”, “tag”:”webedia-prod”, “duration”:”708″} In this way, the processor “generates” an image that emulates 4K quality, improving the sharpness, color and motion processing of the original signal along the way. Therefore, how much the better the processor and the more refined the scaling and enhancement algorithms, the more convincing the result will be, reducing the difference between native content in 1080 and 4K. Amazon Prime Video, for example, has entire teams dedicated to ensuring make your signal look good on every type of screen and in every network condition. In practice, a high-end TV from Sony, Samsung or LG with a powerful processor can improve its quality when a 1080i game is displayed on a 4K panel. There is more detail, less noise, and the movement of the ball loses that artificial texture that poorly scaled signals have. On the other hand, with an entry-level television that does not have a reliable image processor and does not have optimized scaling algorithms, the signal is shown as it arrives: a 1080i expanded to cover the 4K panelbut without providing any improvement to the resulting image.

SpaceX wants to reach a capitalization of 1.75 trillion dollars. Analysts are clear that it is worth less than half

SpaceX’s is the first of the record-breaking IPOs that are expected this year: it will take place on June 12, 2026 under the symbol SPCX. This operation promises to be the most important public offering of shares in history, and the company has already indicated that its objective is to obtain funds worth $75 billion to achieve an astronomical valuation of 1.75 billion euros. But how SpaceX is valued is one thing, and how analysts value it is quite another. Overrated. The financial analysis firm Morningstar has carried out an analysis of SpaceX’s financial accounts and have reached a striking conclusion: “We believe the company has been significantly overvalued and investors will have the opportunity to buy the shares at more attractive levels after the IPO.” Or what is the same: they advise not participating in that initial IPO, and waiting because they anticipate that the stock will fall in the first days on Wall Street. It’s only worth half. In these conclusions, Morningstar establishes that the valuation discounting SpaceX’s cash flow is $780 billion. That represents 48% than the valuation of the private market, which is 1.5 trillion dollars, and 44.5% less than the valuation attributed to the company itself, which amounts to 1.75 trillion dollars. Is it really more promising than Nvidia? Dan Coatsworh is one of the main analysts at the firm AJ Bell, and he commented on CNBC how that theoretical internal valuation of $1.75 trillion would mean that the value of SpaceX (P/E, Price to Earnings ratio) is 67 times its sales, two times more than, for example, happens at Nvidiathe most valuable company on the planet today. Beware of xAI. One of SpaceX’s theoretical strengths is its artificial intelligence division, xAIbut analysts explain that in reality its theoretical advantage is “undetermined”, and in fact they pose it as “a material threat of value destruction” for the parent company, SpaceX. Morningstar believes that the AI ​​division is worth $170 billion, and that what really matters is something else. The Starlink engine. SpaceX’s real argument for going public and its real strength is not the reusable Falcon 9 rockets, but the profitability of Starlink. The company’s satellite constellation has achieved sustained cash flow in recent months, and its global customer base is growing at an enviable pace. It is undoubtedly SpaceX’s great recurring revenue generation machine. Morningstar values ​​it at $611 billion. The double class trick. SpaceX plans to sell shares at a fixed price of $135 per share, but they will only list 3% of the total shares. In addition, Elon Musk will continue to maintain tight control of the vote with 85% of the total through a dual-class share system. Class A shares, those that go public, allow the right to one vote per share. Class B shares go to the founder and the first key investors. They are not sold on the open market, and each one usually gives 10, 20 or more votes. Institutional dependency. The value of the company, however, is supported by the contracts it has with the US government. Specifically with NASA and with the Department of Defensewhich depend entirely on SpaceX systems for their critical missions. That not only guarantees long-term income, but is a compelling argument to attract more conservative investment funds. Either you believe Elon, or you don’t. We are facing an operation that will test Elon Musk’s real power over the markets. Although SpaceX is an extraordinary company, it is overvalued due to its founder’s habit of selling hype.

Adidas has managed to get all of Spain to wear the National Team shirt. It has also managed to get almost no one to buy it from Adidas

I’m sorry I can’t link it but the other day I read a tweet that said something like: “In these moments of extreme polarization, there is only one thing that unites all of Spain: the fake National Team shirt.” In cascade, there were the answers. One after another, fans fed up with the abusive price of football shirts, an accessory that It is already transversal to the sport itself but for which many are not willing to pay more (much more) than 100 euros for a product that you can have at home for just over 20 euros. At the gates of a World Cup, with a Spanish team that excites and a shirt that has had a deep impact since its presentation, the team’s second kit, the white one, can already be seen everywhere. And, of course, it’s not always official. It complicates your month According to Bankinter datathe median salary in Spain for a man was about 26,000 euros in 2024, the latest data published. That of women was just over 22,000 euros. That leaves us with a gross salary, of course, in 14 payments of just over 1,800 euros for them and less than 1,600 euros for women. With that salary, whoever wants to buy the official shirt of the Spanish National Team, replicating all its details, will be dedicating around 15% of the money that enters their account at the end of the month. Official Authentic T-shirt: 150 euros Player name: 20 euros FIFA patch: 10 euros Euro champion patch: 7 euros The accounts come out quickly and easily: 187 euros It is what it costs to wear the same shirt with which Lamine Yamal will take the field in Atlanta (United States) on June 15 at 6:00 p.m. (peninsular time) to face Cape Verde. That, of course, if you manage to get your hands on any of the t-shirts that They have already flown from the Adidas website. For much less, just 23 euros, you can have a replica at home in less than two weeks. It’s not that I asked one of the many in my close circle who have already gotten one. There is simply a website that ranks ahead of Adidas itself on Google. The German company says that “Spain’s away shirt pays tribute to this country’s incredible literary legacy, with intricate prints inspired by manuscripts, a nod to the cultural depth of the Spanish language that connects culture and football.” Let’s say that that other website does not offer such a literary description but what is certain is that there must be plenty of clients. The (pen)last example The second Adidas kit has highlighted the rise of fake t-shirts replicas and the enormous popularity they have garnered in recent years. Sid Lowea British sports journalist welcomed by the Asturian community, echoed this article in Digital Freedom in which the enormous popularity of Spain’s second shirt is mentioned. The one that no one seems to have paid at the price that Adidas lists on its website. Click on the image to go to the original tweet The responses criticizing the high price of the official set and the defense of getting one, let’s say, less official are repeated one after another. Click on the image to go to the original tweet The answers seem to concentrate each and every one of the issues surrounding the underworld that football shirts have become in recent years. Those of us who have dressed Saturdays, Sundays and summer holidays in football shirts and shirts know that replicas do not have the same feel as an original. No? Sure? Without a doubt, it looks a lot like him. It’s something I’ve known from conversations with friends and because… well, he who is free from sin… An example: Real Madrid shirt 99/00. Pushed by the nostalgia effect dosmilerothe aftershocks multiplied their presence in the streets. To the point that Adidas took advantage of the pull to reissue them and make good money. At least, to get mine and that of enough fans who spend our 110 euros to buy a shirt with more than a quarter of a century of history. In my case it was because I wanted to have the shirt with which Raúl dribbled past Santiago Cañizares to score Real Madrid’s third goal in the Champions League Final in Paris. He wanted “the one on Eighth”, the black one. Because the white one had already been given to me a few months before and this one was not entirely true. And, despite this, I had to go to the closet to rescue the shirt that I was wearing when I was eight years old and had an R. Carlos (3) on the back to certify that it did not have the same shiny patina that the official one had. Nor was the stitching of the shield the same, of course. No, it wasn’t the same, but it was almost identical.. And that is enough for many, many of us to wear the shirt of our childhood on the street again. It doesn’t matter if the shirt is from Raúl’s best years, Djalminha wearing Feiraco on the chest of Deportivo de la Coruña or Maradona carrying Buitoni to levels of popularity they never imagined. They all share a single code: they are fashionable. So much so that Adidas has not hesitated to reissue iconic designs from the nineties and 2000s. Without going any further and taking advantage of the return of the World Cup to the United States, For 110 euros you can dress like Clemente’s Spain in 1994. At least, the Germans have had the detail of not reissuing the second kit, forever anchored in a Luis Enrique bloodied. The football shirt phenomenon has become a transversal fashion that transcends genres, decades and teams. They are there when you go to buy bread, when you have a party with friends and when you go to the summer music festival. That has also created a … Read more

Microsoft believed it would take decades to have a useful quantum computer. Majorana 2 just pushed that deadline to 2029

Finding the Majorana particle would be the best thing that could happen to them. quantum computers. The Italian physicist Ettore Majorana mathematically described its existence in 1937, and since then many researchers have become obsessed with it because it has a characteristic that makes it unique: it is both a particle and its own antiparticle. What makes it very attractive for quantum computing is that, when it appears, it does so in pairs and its topological nature gives it a resistance to external noise that conventional qubits do not have. This distribution of information at two separate points means that local errors triggered by vibrations, temperature or radiation cannot easily erase it. The coincidence of this duplicity and its stability suggests that these particles could be used to make qubits that are more stable and less prone to external perturbations than the qubits used in current quantum computers. Or that, at least, is what Microsoft is pursuing, although with an important nuance: it sounds very good, but after the cold water of 2021 physicists are extraordinarily careful when dealing with them. Microsoft promises to have a functional quantum computer in 2029 Microsoft does not work with Majorana fermions in the strict sense of the elementary particle predicted by Ettore Majorana. What you are looking for are Majorana modes or Majorana quasiparticles: collective excitations that emerge in certain topological superconducting materials and that behave as if they were Majorana fermions. They are not fundamental particles; They are emerging phenomena in the field of condensed matter. This strategy allowed Microsoft officially present in February 2025 Majorana 1, the first topological quantum processor. However, the scientific community received it with skepticism. And it did so because the Redmond company claimed to have created a state of matter in silicon that until then it only existed in theory. His proposal was to use Majorana modes as a basis for more stable quantum computing. Majorana 2 has been developed with the help of Discovery artificial intelligence The problem is that Microsoft had tried to demonstrate something similar before, in 2018, and the scientific article that supported it ended up being retracted by Nature three years later. Majorana 1 was, in that sense, both a technical advance and an attempt to regain credibility. And now Majorana 2 arrives. Microsoft has confirmed that this new quantum processor has been developed with the help of its artificial intelligence (IA) Discovery, and has also explained that it incorporates new materials with the purpose of accelerating the arrival of an error-resistant, and therefore fully functional, quantum computer. Chetan Nayak, CTO and Corporate Vice President of Quantum Hardware, has explained that the Microsoft Quantum team has improved the materials stack used in Majorana 1 for the purpose of create a more stable topological phase. Majorana 2 replaces aluminum with lead, and upgrades the semiconducting active region to a combination of indium arsenide and indium arsenide-antimonide. This change in materials has triggered, according to Microsoftsignificant performance improvements. And it also helps protect the fragile qubits of cosmic disturbances that can destabilize them. Be that as it may, this statement from Nayak summarizes the impact that Microsoft believes Majorana 2 will have on its roadmap: “Based on this rapid progress, we are accelerating our plan toward a scalable and practical quantum computer: we have cut our schedule in half and now aim to reach this goal in 2029.” It is an ambitious promise. And with Microsoft’s track record in quantum computing, the scientific community has reason to continue to be demanding when evaluating it.

Antimatter has a property that has taken physicists decades to measure. CERN just did it a hundred times better than anyone else

Antimatter is fascinating not only because of its essence; It is also due to the still enigmatic role he played in the origin of the universe. Scientists still do not have the necessary tools to understand with any precision the role of this form of matter in the formation of the cosmos and the mechanisms that govern the tenuous line that delimits the imbalance between matter and antimatter. Fortunately, what they do know are its constituent elements and some of its properties. Understand what is antimatter It’s not difficult. And we can observe it as an exotic type of matter that is made up of antiparticles, which are particles with the same mass and spin as the particles we are familiar with, but with the opposite electrical charge. In this way the antiparticle of the electron is the positron or antielectron. And the antiparticle of the proton is the antiproton. Antimatter has a surprising property: when it comes into direct contact with matter, both annihilate, releasing a large amount of energy in the form of high-energy photons, as well as other possible particle-antiparticle pairs. It is currently being studied in many of the most important research centers specialized in particle physics in the world with the hope that knowing it better will help us understand some of the mysteries of the cosmos that remain out of our reach. The hyperfine cleavage of antihydrogen has been revealed CERN’s antimatter factory produces this form of matter by firing high-energy protons from an adjacent synchrotron at a metal block. This process generates a cascade of secondary particles, and among them antiprotons arise. These latter particles can then be cooled to be used in the facility’s experiments. ALPHA (Antihydrogen Laser Physics Apparatus or antihydrogen laser physics apparatus), which is one of them, is specialized in producing antihydrogen by fusing antiprotons with positrons. Researchers then use magnetic fields to trap the antihydrogen for further study. An antihydrogen atom is composed of an antiproton in its nucleus and a positron orbiting around it, in the same way that a hydrogen atom contains a proton around which an electron orbits. Deuterium and tritium, the two isotopes of hydrogen, also have one or two neutrons in the nucleus respectively. The researchers of the ALPHA experiment have achieved something amazing: have measured hyperfine division of the ground state of the antihydrogen atom with a precision of 4 parts per million, improving the previous result by two orders of magnitude. This milestone is very important because it allows very rigorous tests to be carried out in the field of quantum electrodynamics. Hyperfine splitting of the ground state of the antihydrogen atom is the small splitting of the lowest energy state of the atom due to the magnetic interaction between the antiproton and the positron. According to the fundamental symmetries of nature, this measurement should be identical to the equivalent effect observed in hydrogen. Be that as it may, this milestone is very important because it allows very rigorous tests to be carried out in the field of quantum electrodynamics, which is the most precise theory that explains the interactions that occur between charged particles and light. Jeffrey Hangst, the spokesperson for the ALPHA experiment, explains that “the hyperfine splitting of the ground state of hydrogen is the origin of the so-called 21 centimeter lineso prized by radio astronomers and researchers searching for extraterrestrial intelligence (…) When the antimatter factory was conceived in the 1990s, the hyperfine splitting of antihydrogen was one of the key measurement objectives justifying the construction of the facility.” “The current measurement represents the culmination of many years of effort,” Hangst pointed out. “We have pursued the precise determination of the hyperfine splitting of antihydrogen since we demonstrated how to trap antimatter atoms in 2010. And now another group in the antimatter factory, the ASACUSA collaboration, is also trying to study this very important transition. Their technique, if demonstrated, has the potential to achieve even greater precision.” Thanks to ALPHA’s high level of precision, the measurement of hyperfine cleavage is sensitive to the effects of the internal structure of the antiproton at the center of the antihydrogen atom. In any case, this result is a very important step in the effort to further explore the nature of antimatter.
