The MIT has just placed us closer to the great milestone in quantum computers: error correction

by

The rapid development you are experiencing Quantum computing He is gradually dismantling the opinions that question the potential of this discipline. One of the biggest challenges to those who face is the need for quantum computers to be able to amend your own mistakesand three different studies defend how close we are to achieve. A Australian quantum research group, another Dutch and a third Japanese team published in Nature In January 2022 as many scientific articles in which they explain in detail the procedure they used to put superconductor cubits that have precision greater than 99%. When errors are so rare it is much easier to correct them. In the other saucer of the balance, Gil Kalai remains erect, an Israeli mathematician and teacher at Yale who He has predicted that quantum computers will never be able to amend their mistakes. According to this researcher, the increase in the number of states of quantum systems and their complexity will cause them to end up behaving like classical computers, so the superiority of the former will end up evaporating. The MIT has taken a firm step forward Before we investigate the achievement of scientists from the Massachusetts Institute (Mit) It is worth briefly reviewing what one of the companies that is contributing the most contributing to the development of quantum computers: IBM has achieved in the field of errors. The itinerary that published in December 2023 He anticipated that before the end of 2024, the Heron (5K) platform endowed with error mitigation would be ready. And this company He fulfilled his promise. The main problem facing quantum computers in the field of error correction is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. The strategy for which many of the research groups that are involved in the development of quantum computers are opting for monitoring the operations carried out by the cubits for Identify real -time errors and correct them. The problem is that from a practical point of view this strategy is very challenging. The mitigation of errors allows the cubits to carry out their calculations even if they have errors and only at the end of the process it is inferred what the correct result is However, there is an alternative path. It is known as ‘error mitigation’, and, very broadly speaking, instead of monitoring in real time what happens in the cubits allows them to carry out their calculations even if they have errors and only at the end of the process it is inferred what the correct result is. This technique is already delivering very promising results. In fact, this characteristic is what allows the quantum processor to argue the other quantum chips developed by IBM so far. What MIT researchers propose in the article in the article that they have published in Nature Communications It is a different approach to the correction of errors. In fact, in their text they describe how they have achieved Attach artificial atoms and photons with the purpose of using this mechanism to process quantum information at a higher speed than the prototypes of current quantum machines. This peculiar type of coupling between light and matter can be used to make very robust cubits and capable of processing information up to ten times faster than a quantum processor such as those currently available. Yufeng Ye, the main author of this article, He maintains that “This technology would eliminate one of the bottlenecks of quantum computers. It is usually necessary to measure the results of the calculations between error correction rounds.” In this statement this scientist has done something very important: he has established a relationship between the strong coupling of light and matter that can presumably be used to produce a new type of cubits and error correction. “This strategy could accelerate the moment in which we will reach quantum tolerant to failures and we can develop real applications with practical value,” says Ye. It sounds really good, although we should not overlook that what these scientists have done at the moment is a demonstration of fundamental physics. The challenge from now on is to bring this technology to practice.

Meanwhile, if you had not touched your chromect, I should return to life in a matter of hours. In Xataka Basics | Seven unusual things for which you can use your chromecast with Google TV

One of Tesla’s parents points to the most recurring error of electric cars

by

When maximizing the Autonomy of electric carsthere are two very clearly differentiated currents. The first commitment to brute force, by gigantic batteries or the improvement of their density to get a higher performance. The second option is what is committed to better aerodynamic efficiency and engines. In this last route we have found companies like Mazda, who They were fully positioned against of the larger batteries Since, according to them, they suppose an overweight that not only must move, the dynamics of the vehicle also worsen. Mercedes, although in some of his cars he has huge batteries, also explained the day we got into Spectacular Mercedes Vision EQXX that its strategy involves improving the efficiency of engines and aerodynamics. In fact, next Electric Mercedes It should be the best expression of the latter. Now it has been the CEO of Lucid Air, one of the parents of Tesla Model S, who has positioned himself in this current of thought. The company aspires to fight for Tesla for offering the most efficient electric car in the market and its CEO is clear: “Many electric cars are why.” A clear bet to consume less The words of Peter Rawlinson, CEO of Lucid Air, are aimed at the concept of the electric car itself, which explains in an interview with Coach. According to Rawlinson, so far manufacturers have focused on offering electric cars as a way to reduce pollutants of CO2. That has forced them to include huge batteries if they want to achieve the greatest possible autonomy with the least effort. But that, for the Lucid Air CEO, is a wrong approach. Your approach walks in the direction of betting on the electric car to get “a better car” And not an electric solution of the same thing we already have. And that inevitably goes through efficiency. “Not only by making a car more efficient, it is using less energy in the world, but is also using less battery and mineral resources,” he explains in his interview. “He Lucid Air Pure is literally the most energetically efficient car in the world. It uses less energy to go from A B, whatever its fuel, than any mass production car in the 130 years of car history, “he defends. To defend these data, Rawlinson is based on the MPGE calculation that is done in the United States. To compare the consumption of electric cars with gasoline, it compares how many miles would be able to travel an electric car if you used a gallon of gasoline (3,785 liters). In Car and Driver They also talk about Lucid Air Pure as the car with greater autonomy they have tried. The point is that for the Lucid Air CEO this has huge advantages. First because “less minerals and resources are used (…) that means less lithium mines, less cobalt mining, less nickel” so, as we said, it is not only a matter of CO2. That also because if you need less electricity, it will produce a lower carbon footprint. But, in addition, it assumes the Mazda approach. If the car is less heavy it is more agile and is more comfortable and pleasant to drive. It also specifies that it is a clear improvement in front of the gasoline car. Defends that a more efficient car is irremediable than present Worst benefits But this is not so with an electric car. If the latter manages to put smaller batteries, he wins in dynamism while maintaining benefits that leave behind the car moved by fossil fuels. All this add reasons to leave us before many electric cars that “are why.” They have “very poor” autonomies because they have focused on reducing car costs to the maximum and, among them, the size of the batteries. However, without adequate technology, these batteries are removed less than they could deliver. If engines efficiency would be improved, those same cars could travel many more kilometers. Rawlinson points out that this is one of the reasons why electric car sales are stagnant in the United States: “At this time, we do not have a safe infrastructure and we do not have enough cars with large autonomies. That is why it is a horrible experience.” Words that sound to us in Spain and that, luckily, we are leaving behind.

That the 16e 16e iPhone 709 euros seems to me an error. For less than that price, these five mobiles seem more interesting to me

by

I had been waiting for the announcement of the new iPhone for a long time that I would highlight for its value for money, but after the presentation of the iPhone 16E And seeing its price … It was like a jug of cold water. Rumors suggested that approximately 599 euros would be launched, a figure that is far from its official price of 709 euros. There are currently other mobiles that, although it is true that they do not offer the same – they can do it. iPhone 16-, I am much more interested, and some are much cheaper. Xiaomi 14t Pro by 619.98 eurosone of the mobiles with better value for money within the Xiaomi brand in its 512 GB version. iPhone 13 by 499 eurosa mobile that has been highlighting for a long time for its value for Apple. Google Pixel 9 by 699.90 eurosone of the best mobiles of last year that stands out for many reasons. Samsung Galaxy S24 by 649 eurosa phone that comes with a screen that is a real delight. Motorola Razr 50 by 599 eurosa very interesting folding mobile for the price it currently has. Xiaomi 14t Pro He Xiaomi 14t Pro It launched at an official price of 899.99 euros, so at that time the one that had the best value for money was the Xiaomi 14t. However, the last offer of PCComponentes, which leaves it for 619.98 eurosIt makes it an even more interesting option. We talk about one of the mobile phones with better value for money within the brandand it is a great alternative to the 16E iPhone. Does not have the options for Apple Intelligencebut it does come with some artificial intelligence functions, its cameras signed by Leica offer very good photographic results, performance is excellent thanks to the Mediatek Dimensity 9300+ processor and its AMOLED screen offers a very good image quality. Besides, This version has 512 GB of storage capacity. * Some price may have changed from the last review iPhone 13 The 16E iPhone was going to be, when it was thought that its nomenclature would be iPhone Se 4, a mobile that would highlight above all in its value for money. It is more expensive than we thought, so we do want make the leap to Apple’s ecosystem for the least possible money —And without resorting to the reconditioned, the iPhone 13 It is still a very good purchase option despite the fact that it was launched a few years ago. Can be found in Mediamarkt by 499 euros. Nor is it compatible with Apple Intelligence – the AI ​​reserves the most recent Apple mobiles – but it has Wireless load via Magsafe (The 16E iPhone is not compatible), You will still receive software updates For a few years and its price in Mediamarkt is very competitive. * Some price may have changed from the last review Google Pixel 9 If we can do without Apple Intelligence, but we want to have artificial intelligence functions on the phone, a good purchase option is the Google Pixel 9one of the best mobiles last year. At the moment It can be found in its 256 GB version by 699.90 eurosa very interesting price considering that the officer is 999 euros. Among what is most highlighting Google’s mobile, we find a good screen that does not move too much to the size of the iPhone 16E; That is, riding a 6.3 -inch panel. Besides, will continue to receive software updates for many yearsthe cameras offer very good results and their software works very well. * Some price may have changed from the last review Samsung Galaxy S24 After launching the Samsung Galaxy S25the price of Samsung Galaxy S24 It has come down. It is not the most recent, but continues to offer (and will continue to do it) a very good experience. In recent months we have been able to see a wide variety of prices on this phone, being the current one of the lowest. Can be found in Mediamarkt by 649 euros. The Samsung Galaxy S24 is interesting for several reasons. It is ideal if we look for a relatively small mobile (6.2 inches), its autonomy is quite good and we will not have problems to squeeze mobile functions, The Lpto screen is a delight And, like Google’s mobile, you will receive many years of Android updates. Samsung Galaxy S24 (128 GB) * Some price may have changed from the last review Motorola Razr 50 Although the folding mobiles They usually have quite high prices, one of the last (and best) offers from Mediamarkt is Motorola Razr 50an interesting mobile if we are looking for a telephone with good design, with a generous external screen in size and, of course, a good price. Can be found in the store for 599 euros in his 256 GB version. One of the particularities of Motorola Razr 50 is that we can have a phone with a 6.9 inches screen in a compact terminal Thanks to its folding pohed panel. Its processor is the MediaTak Dimensity 7300X and its software is very clean. In addition, it also has some artificial intelligence functions, in this case Gemini.

The human error that causes anxiety in dogs, according to experts

by

Renowned veterinarian Amir Anwary issued an important warning to dog owners: certain seemingly harmless behaviors could be contributing to the development of separation anxiety in your pets. In a recent video posted on his TikTok account, the specialist explained the most common errors and shared key strategies to prevent this problem. The impact of exaggerated goodbyes and greetings One of the most common mistakes owners make, according to Anwary, is making excessively emotional farewells and greetings. These interactions can confuse dogs and cause stress. Separation anxiety in dogs can be avoided by following specialist advice.Credit: Hanna Taniukevich | Shutterstock “Keep calm when you leave home and when you return. When you leave home, You make it a big scene and when you come home, you make it an even bigger scene”explained the veterinarian in his video. Likewise, Anwary recommended avoid approaching the dog during the ten minutes before leaving the house and upon returning. Although this measure could seem “cruel” to some owners, the expert assured that It is one of the most effective ways to prevent separation anxiety. Strategies to reduce anxiety To help dogs stay relaxed during their owners’ absences, Anwary suggested ensure they get enough physical exercise before being left alone. A long walk can help the animal feel calmer and more tired, which reduces its anxiety level. Besides, keeping pets mentally occupied is essential. Leaving them puzzles with treats can be an effective way to stimulate their minds and provide them with a positive task to focus on while they wait for their owners to return. A gradual adaptation system For cases where dogs must be left alone for long periods, Anwary advised implementing a gradual approach. “When you leave the house, start by leaving for five minutes and watch your response.”he explained. This method allows pets to progressively get used to the idea of ​​being alone, minimizing the emotional impact of prolonged absences. In situations where these strategies are not enough, the veterinarian urged you to go to an animal behavior specialist. These professionals can offer a personalized approach to treating separation anxiety and guide owners in managing their pet’s behavior. The key, according to Anwary, is foster an environment of calm and emotional balance for petshelping them face their owners’ absences without anxiety and ensuring them a healthier and happier life.

Spain’s attack gets stuck against Norway and the Hispanics are left with no margin for error to qualify for the quarterfinals

by

Spain Qualification for the quarterfinals of the World Cup has been complicated after losing to a Norwegian team that, despite not reaching its best moment, punished the irregularity of the national team. Those of Jordi Ribera They had a good first half, but ran out of steam in the second half. In the second phase, the ‘Hispanics’ They no longer have any margin for error. The defeat against Norway has been like a shot in the foot and each game for Spain will be a match ball. Portugal will be the first obstacle, while if they win, the pass will be decided against Brazil. The defeat took place in the second half when the Spanish players failed to be successful in front of goal. Spain, which led by four, conceded a 4-9 partial in the final minutes that caused the first defeat in the World Cup. A result that few could have predicted with twenty minutes remaining with the five goals advantage (14-19) that the Spanish team had, whose attack was choked with seven field players that the Nordic team proposed in the final stretch. Quite a setback for Spain, which, aware of the delicate situation in which the hosts arrived at the event, who had zero points in their locker, seemed willing to exploit the nervousness of the Norwegian team with a forceful start to the game. Spain, from more to less To do this, Jordi Ribera did not hesitate to bet on the presence of the brothers. Dujshebaev who responded to the coach’s confidence with three consecutive goals from Dani, the youngest of the saga. An offensive efficiency that allowed the Hispanics to take a two-goal lead (1-3) that seemed like it could make Norway falter, very touched after its bad first phase. But it was the Spanish team itself that was in charge of rescuing the Nordic from his doubts with several untimely losses of the ball that allowed Norway to run. A circumstance that condemned Spain to see how those of Jonas Wille Not only did they erase their disadvantage, but they turned the score around 4-3 in just two minutes. It was enough, however, for those from Ribera to minimize their offensive mistakes led by a spectacular Alex Dujshebaev, who took over the scoring from his little brother, so that the ghosts would appear again to the Norwegian team. Forced to attack statically, the local players began to get more and more entangled in the defensive framework of the Spanish team, which with legs and more legs took the Nordics to the brink of passiveness in each of their offensives. The ideal breeding ground for Norway’s mistakes to emerge, which Spain did not forgive and punished with several consecutive counterattacks to lead by two goals (9-11) with just over ten minutes to go before half-time. Sagosen, the key to the match But the goalkeeper’s emergence Andre Kristensenwhich made three consecutive stops, prevented the escape of the Spanish team, which increasingly firm in defense managed, despite everything, to go into the break with a lead of three goals (10-13) on the scoreboard. The Hispanics managed to extend that difference to five (13-18) thanks to a sensational defensive work, in which the young man shone again, as happened against Sweden. Ian Barrufetand the goals of Imanol Garciandia which, with its cannon shots, unblocked the Spanish attack. However, there was still a lot for those from Ribera to suffer, as he was responsible for remembering. Norwegian star Sander Sagosenwhich seemed to be resurrected with the move to attack with seven field players proposed by the Nordic coach. A change that stuck for Spain, which saw its advantage reduced to just one point (21-22) with just over ten minutes remaining, forcing Ribera to urgently request a time-out. Petar Cikusa tries to escape the pressure of the Norwegian players. EFE

Patient dies due to hospital error asking the wrong family about disconnecting life support

by

This sounds like a nightmare, but it really happened. In summer 2021, David Wellsa 69-year-old man, arrived at PeaceHealth Southwest Medical Center in Vancouver, Washington, after an accident in which He choked on a piece of meat and fell unconscious.. What happened next is something that even in the worst horror movie you couldn’t imagine. It turns out that, due to an identification errorWells was mistaken for his roommate, Michael Beehler. The hospital contacted Beehler’s sister, Debbie Danielson, and asked if she wanted to turn off life support for who she believed was her brother, since he was supposedly with “brain death”. Without thinking too much, Debbie made the difficult decision to authorize the disconnectionbelieving he was ending his brother’s life. Debbie then organized the funeral, wrote the obituary and mourned the loss of what she thought was her loved one. But on August 14, an unexpected call shocked her. His brother Michael was alive. He receives a call from his “dead brother” “I told him, ‘You can’t be alive. You’re dead!’”Debbie remembered, completely surprised. From there, everything was chaos. The medical examiner confirmed that the body presumed dead was not Beehler’s, but Wells’. But that’s not all, since the worst of all is that Wells’s son, Shawn, did not find out about the mix-up until 2023, when the story was revealed in the media. “I have no words to describe how poorly they handled this. “I can never take that decision back,” Shawn said, devastated. And even though his father David Wells they had detected him brain deaththe family was not consulted to disconnect him, although the hospital thought so, but the call was made to the family of Michael Beehler. The incident was so serious that the Washington Department of Health investigated what happened. The hospital had not implemented a proper process to verify patient identities, resulting in this fatal error. Affected family sues Although no sanctions were imposed, the hospital said it took steps to improve its identification procedures. But the Wells family, along with Beehler and Danielsondecided to sue the hospital and other entities involved, including ambulance and funeral homedue to negligence and emotional distress. They are seeking justice for the terrible mess that changed their lives forever. For its part, the PeaceHealth hospital issued a statement in which it defended its care and explained that everything happened during the difficult days of the COVID-19 pandemicwhen hospitals were under enormous pressure. Despite this, the affected family cannot help but feel that such a serious mistake should never have happened. Keep reading:
