Universal quantum computers promise to change the world. Now they are closer thanks to giant super atoms

by

The prototypes of quantum computers currently manufactured by IBM, Honeywell or Google, among other companies, are engineering prodigies. However, they have defectswhich currently greatly limits the range of applications in which it is possible to use them. The most important of all of them is that they make mistakes and they are still not able to correct them effectively. Scientists are working on developing advanced error correction systems, and if they achieve their goal, universal quantum computers capable of dealing with a wide range of problems will arrive. The Achilles heel of current quantum machines is the extreme fragility of their qubits. And they are very sensitive to disturbances from the environment. Their interaction with the space around them can cause quantum information to be lost or altered, preventing them from delivering a correct result. This phenomenon is known as quantum decoherence and it has the ability to degrade the quantum states that need to be protected in order to carry out operations with qubits. Currently, researchers are making an enormous effort to design effective strategies for isolating qubits from the environment. However, efforts are also being made to develop less fragile qubits, and therefore less sensitive to noise. This is the plan that several scientists at Chalmers University of Technology in Sweden are working on. And they have developed a completely new quantum system designed to protect quantum information and minimize interference from the environment. Its purpose is, neither more nor less, to pave the way for universal quantum computers or large scale. Less decoherence leads to more robust and higher quality quantum computers Quantum computing experts maintain that quantum computers that will have the ability to correct their own errors can be used to design exotic materials, and probably also to develop new drugs and in industrial optimization problems, among other tasks. These are some of the applications that the qubits implemented with giant superatoms proposed by the Chalmers University of Technology team led by applied quantum physics professor Anton Frisk Kockum could put in our hands. Giant Superatoms explore two ideas long known to quantum physicists: giant atoms and superatoms. Giant Super Atoms explores two ideas long known to quantum physicists: giant atoms and superatoms. Unlike isolated atoms, a giant atom in this context is an artificial qubit designed to interact with its environment using light or sound waves at multiple physically separated points. This peculiarity allows them to protect quantum states more effectively than conventional systems, reduce decoherence and remember past interactions. The problem with using giant atoms in quantum computers is that they have significant limitations when trying to entangle them. Entanglement is essential in quantum computing because it allows multiple qubits to share a single quantum state and act as a coordinated system. To solve this limitation, the Chalmers researchers have combined giant atoms and superatoms. A superatom is made up of several natural atoms that share the same quantum state and behave collectively as a single larger atom. Lei Du, one of Chalmers’ researchers, explains to us what is a giant super atom: “We can observe it as multiple giant atoms working together as a single entity, allowing them to exhibit a non-local interaction between light and matter. This allows quantum information from multiple qubits stored and controlled as a unit and without the need for increasingly complex surrounding circuits.” For the moment, giant superatoms are a theoretical proposal, but Professor Anton Frisk Kockum and his team are going to try to build a quantum system using them. If they succeed, they could have found a new type of qubit that is much more robust, and, therefore, suitable for use in the development of universal quantum computers.

Quantum computers are going to overthrow classical cryptography sooner than expected

by

Just two weeks ago a group of researchers from the California Institute of Technology (Caltech), the University of California at Berkeley and the emerging company Oratomic published a scientific article preliminary in which they explore the capabilities of quantum computers of neutral atoms. These machines are an alternative to quantum computers with superconducting qubits and ion traps, and are still in an experimental phase. However, these scientists have estimated that Shor’s algorithm can be implemented using a quantum computer equipped with between 10,000 and 20,000 qubits of neutral atoms. In fact, in their article they even propose a design with which in theory it would be possible break bitcoin encryption in a few days using 26,000 qubits of neutral atoms. In any case, these researchers are not the only ones who in recent weeks have alerted us to the ability to violate classical cryptography that quantum computers will acquire in a relatively short period of time. At the end of last March, Google’s quantum artificial intelligence group published a study in which he demonstrates that the elliptic curve encryption used by Bitcoin or Ethereum, among other cryptocurrencies, can be overthrown using far fewer resources than initially estimated. According to these researchers, a quantum computer with less than half a million physical qubits will be able to decipher the algorithms used by current cryptocurrencies in a few minutes. In short, the scientific community has agreed that classical encryption technologies will be vulnerable before the arrival of large-scale quantum hardware. The first steps to protect ourselves have already been taken Quantum computing experts have known for several years that quantum computers they will end classical cryptography. That moment came in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a D-Wave quantum computer to successfully break SPN encryption (Substitution-Permutation Network), which is a cryptographic algorithm used to encrypt information. This encryption is the cornerstone of, for example, the AES standard (Advanced Encryption Standard), which is used a lot. These scientists published the results of their research in an interesting article titled “Quantum Processing-Based Public Key Cryptographic Attack Algorithm with the D-Wave Advantage.” However, this is not all. And in mid-May 2025, several Google researchers posted an entry in the blog dedicated to the security of this American company in which they maintain a crucial premise: an RSA integer (Rivest–Shamir–Adleman) 2,048 bits can be factored in less than a week with a quantum computer of less than a million qubits. A 2,048-bit RSA integer can be factored in less than a week with a quantum computer of less than a million qubits Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptic curve that is more robust, efficient and difficult to break than RSA, but its mathematical foundations are similar to those of the latter encryption algorithm. In fact, according to the Google scientists who authored the article I mentioned above, if future quantum computers will have a harder time breaking RSA encryption than initially expected, elliptic curve cryptography will also fall relatively easily. So far we have talked about cryptocurrencies, but it is crucial that we do not overlook that encryption technologies play a fundamental role in our daily lives. In fact, WhatsApp and Telegram use them to encrypt our messages; banks turn to them to protect our transactions and every time we buy something on the internet it is encryption that is responsible for protecting our credit card information. These are just some of the applications of this technology. The threat of quantum computers to encryption technologies is very real, but we have no reason to panic because many researchers have been working on the solution to this challenge for several years. In fact, most of the theoretical work has already been done. In 2024, the US National Institute of Standards and Technology (NIST) published an initial set of standards that includes a post-quantum key exchange mechanism and several post-quantum digital signature schemes. The work that has already been done invites us to foresee that the moment relevant quantum computers appear from a cryptographic point of view, the technologies that will be able to protect our information will already be ready.

In 1995 ‘Toy Story’ forever changed the way animated films are made. He did it with rudimentary computers

by

Seen today, ‘Toy Story’ It remains as fresh, fun and surprising as it was in its day. That the later films of Pixar have drawn, to a greater or lesser extent, from its aesthetics, its plot structure and its characters, demonstrates the extent to which the company’s first film was influential and foundational in many ways. And that is taking into account that, technologically, its creative process has lost all traces of sophistication, and today it is a relic of the past like the first attempts at other techniques such as the rotoscope or the stop motion. As an example, this video that dates back to the time of filming but which had not been seen much until recently, and in which Pete Docter, the film’s animation supervisor, describes the rudimentary techniques with which the characters in the film were brought to life, based on the recording of the original voice. Their explanations and images attest to the way almost intuitive that they had to animate, and how perhaps the image that many people have of computer animation as something completely automated and where there is no human participation is absolutely wrong. We must add to this that Docter, in addition to being an animator in ‘Toy Story’, would write the basic story of almost all Pixar moviesthe script for ‘Delverso’ and ‘Up’ and he would direct those same ones and ‘Monstruos SA’. That is to say, apart from knowledge about the creative procedure in the technical part, he is also a key name in the most primitive section of the genesis of the film, where the ideas, the design of the characters and the very threads of the story emerge. In the video he explains how, based on sound, they sketch a series of movements on paper, a procedure that obviously has much more to do with traditional animation than with nothing programmatic. From there they go to a stand-in of Woody, that is, a character “made only with geometric shapes”, to save time on technical issues. In those days it was unthinkable to animate in real time with finished characters. From there, and with extreme precision, it moves the elbow, wrist, fingers… and finally, separately, all the facial animations. The interesting thing is what Docter adds later and that makes clear his interest not only in the technical section of this type of animation, but also in its creative and expressive twists and turns: “If you can make this model act, function and communicate without any type of facial expressions, then you have done a good job.” It’s a perfect example of why ‘Toy Story’ still works and exciting: because it does not remain a technical exhibition in which it was a pioneer, becoming the first computer-animated feature film, but there is a traditional creative work supporting it all. The rendering that gave life to the toys The key to Toy Story’s animation is RenderMan, Pixar’s proprietary 3D rendering software that it developed since the mid-1980s. In addition to using it in its own films, the company makes it available to third parties, as it did, with the software still in its infancy, in films such as ‘The Abyss’ in 1989 (in the scene of the water tentacle that gave the film an Oscar) or ‘Terminator 2’ in 1991 and its liquid metal effects. What RenderMan does It is managing issues such as lighting and volumes realistically, even on computers as primitive as those available in the early 1990s. The success of ‘Toy Story’ made the tool ubiquitous in productions that played a historic part in the birth of computer special effects in cinema. Even today, ‘Toy Story 4’ has been made with an updated version of RenderMan which, of course, manages aspects such as light and shadow projections in an infinitely more realistic way than in the first film. The importance of RenderMan is essential to understand even the origin of the company, because Pixar was born as a division of Lucasfilm that ended up becoming a software company that made short films to advertise the power of its products. After winning an Oscar with the short ‘Tin Toy‘ -shot with the Menv software, also from Pixar-, the decision made by the co-founder of the company Ed Catmull – the original core along with John Lasseter and the screenwriters Andrew Stanton and the aforementioned Docter -, who always had the ambition to make the leap to the feature film, was to make a half-hour Christmas special. In it, a ventriloquist doll made an unlikely couple with the metal ‘Tin Toy’ doll. ‘Tin Toy’ was not short on ambition (things appeared in it that had literally never been seen on that scale, such as textures of different materials such as wood or fabric, or shadows of different intensity), and part of that ambition would be transferred to ‘Toy Story’. For example, Catmull – like the rest of the animators – would provide a character to the dolls that appear hidden under the sofa. It was an elephant, which he designed by introducing Bézier curves by hand, as coordinates, into the programming language. The primitive concept of the metal dummies and the ventriloquist did not prosper, but Pixar ended up with a contract with Disney for 26 million dollars to make three feature films. They decided to extend the story of the toys that come to life from the short, and once again we can see Pixar’s desire for technology and ingenious concepts to come together in the same way: since visually they could not afford sophisticated and realistic animations with the software they used, they would animate toys, which would intuitively have robotic and rigid gestures and behaviors if they came to life. The ventriloquist dummy became Woody because the CEO of Disney at the time, Michael Eisner, had a bad feeling for puppets. Small calculation errors The first problem that Pixar encountered after starting production in 1993 was the equipment they believed was necessary to complete … Read more

The computers of the future have found an unexpected ally to store information: fungi

by

Bioelectronics has been studying for some time the possibility of taking advantage of living organisms in order to produce electrical activity and, in some way, take advantage of it to make our machines work. Although at first glance it could be a topic worthy of the Matrix script, the truth is that there is a whole fascinating world in that of the memristors based on organic elements. Some researchers have found the key to demonstrate how the mycelium of mushrooms such as shiitake can function as a memristor, an electrical component with the ability to ‘remember’ past states. This discovery could be the key to a new generation of sustainable and biodegradable electronic devices. What is a memristor and why does it matter? A memristor is an electronic component that combines the functions of memory and resistance, capable of “remembering” previous electrical states. They are currently manufactured with materials such as titanium dioxide between two metal electrodes, but their production requires scarce minerals and polluting and high-cost industrial processes. Hence the importance of looking for more sustainable alternatives through organic materials. How mycelium works as memory. John LaRocco’s team at Ohio State University grew shiitake mushrooms in Petri dishes until complete development. They then dehydrated them in the sun, turning them into rigid disc-shaped structures that can be rehydrated when necessary. By connecting electrodes to these samples and applying different voltages, discovered that the mycelium presents conductive structures similar to conventional ‘memristors’. According to LaRocco, “if we could develop a microchip that mimicked real neural activity, we could dramatically reduce the amount of energy consumed when the machine is not in use.” The results of the experiment. After two months of testing, the shiitake-based memristor demonstrated the ability to change electrical state up to 5,850 times per second with an accuracy close to 90%. When they applied a specific sine wave, the characteristic figure-eight curve of an ideal memristor appeared, confirming that the mycelium indeed remembers electrical flow. Although performance eventually decreased at higher frequencies, connecting multiple samples improved stability, something the researchers compared to the network effect of neural connections in the brain. Vadvantages over traditional semiconductors. The main attraction of these biological memristors is its sustainability. Mushrooms are developed from organic biomass, they are biodegradable and their environmental impact is minimal. Furthermore, growing them is economical and their production can be easily scalable, from small laboratory experiments to industrial manufacturing. Additionally, fungi have exceptional radiation resistance, which could also make them especially valuable for aerospace applications. Potential applications and pending challenges. The flexibility and scalability of these components opens up possibilities in fields from extreme environment computing and space exploration to autonomous systems and wearable devices. However, significant obstacles remain. And just as they count from Wired, current samples are too large and need to be miniaturized to compete with existing microchips. Furthermore, the electrical properties of mycelium vary between samples even grown in the same medium, which makes its stable industrial manufacture difficult. Next steps in the investigation. The team plans to develop techniques to grow mycelium and give it an ideal shape using 3D printing and methods for incorporating electrical contacts during cultivation. They are also exploring the optimal way to preserve it long-term, combining techniques such as freeze-drying and special coatings. “Society is increasingly aware of the need to protect our environment and preserve it for future generations, and that could be one of the driving factors for new biocompatible ideas like these,” pointed out Qudsia Tahmina, co-author of the study. Beyond mushrooms. This is not the only organic material that has demonstrated ‘memristive’ properties. Researchers from other universities They have experimented with honey and human bloodexploring their possibilities as biodegradable electronic components. Honey, for example, can change resistance in just 500 nanoseconds and is completely biodegradable. In the case of blood, scientists in India discovered in 2011 that it could function as a memristor by applying different voltages, keeping the resistance stable for at least 30 minutes.

RAM has become so expensive that it already distorts the market. “Pre-assembled” computers have just appeared on the scene

by

There are times when a seemingly secondary component reveals that the market no longer works as it used to. RAM is starting to fill that role. Its price and availability his no longer an assumed detail to become a factor that alters basic business decisions, from how the final price of a PC is set to what is included, or not, in a standard configuration. When that happens, we are not just talking about rising prices, but about a silent change in the rules of the game. The clearest sign of this shift has come from Paradox Customs, an integrator founded in 2019 in Deer Park (New York) that has opted for something unusual: allowing the customer to configure a computer without RAM memory. The company explains it in its account in Xdue to continued shortages and escalating prices, offers the option to select “no RAM” in the purchasing process. It also presents it, for those who already have modules or can obtain them on their own, a direct way to overcome a market that no longer guarantees stable supply at predictable prices. Click to see the original message in X When RAM rules. The increased cost of memory not only adds to the budget, it also decompensates the internal logic of a configuration. A PC that was previously adjusted by changing the CPU or graphics card may now be out of range solely because of the RAM, forcing you to cut back on other components or rethink the whole thing. In this scenario, memory stops being a silent accompaniment and begins to dictate decisions that affect the overall performance, the usage profile and the perception of value of the final equipment. Strategies to survive. Faced with the same problem, the market is reacting in very different ways. CyberPowerPC, for example, notified of price changes as of December 7, 2025, attributing them to “market conditions.” Framework, however, He assured that the price of his memory has not changedbut it withdrew the sale of stand-alone modules from its store to stop resellers and reserve inventory for those who buy the memory along with their laptops. There is no single solution, only adjustments to buy time in an unstable scenario. The pressure of AI. Behind this tension there is not a single factor, but a profound change in demand. Data centers dedicated to artificial intelligence require large volumes of memory, and that is reordering priorities in the industry. Another pressure is being reported in the sector, part of the production capacity of manufacturers such as Samsung or SK Hynix would be directed towards HBM, a higher margin memory designed for accelerators and servers, which reduces the margin for conventional consumer RAM. The effect is not immediate, but it is cumulative, and ends up being noticeable in the domestic market. This context does not affect all actors equally. Specialized integrators, like Paradox, buy components on the open market, so any swings in pricing or availability are often quickly translated into their offering. Large manufacturers, such as Dell or HP, operate with scale, much higher volumes and supply chains designed to operate at a global level, which tends to better cushion these types of fluctuations. This difference helps to understand why some react with visible changes in the configurator and others do so in a more gradual and less explicit way. Visible changes. The scene left by this change is clear, the pre-assembled computer seems to be entering a different stage, except in these months. Memory has gone from being an invisible component to a factor that rewrites catalogs and business decisions. For now, the public signals that some manufacturers are leaving point to an unstable scenario, with defensive measures and warnings of price changes.

millions of computers will end up in the trash

by

On October 14th the end of support for Windows 10. This is bad news from a security point of view because it leaves millions of computers without security updates. There is another reason that makes Microsoft’s decision a terrible idea: the enormous amount of garbage that will be generated. what has happened. Microsoft has ended support for Windows 10 ten years after its launch. It seems like a longer period, the problem is that there are still many people using this version. In addition to the risk to the safety of this equipment, in 404media They highlight the environmental issue. Although not everyone who has a Windows 10 computer is going to throw it away the same day support ends, the decision will cause many to end up renewing their computers for this reason. There is also the particular case of large organizations, such as educational or government centers, that probably have regulations that prevent them from using outdated equipment, so they will have to renew them en masse. Why is it important. When Microsoft decided to end support for Windows 8, the version only had a 4% market share. The problem is that Windows 10 is installed on 43% of devices, which in concrete numbers is 400 million computers. The consumer organization PIRG warns that such a large amount of equipment has never been left unsupported at once and they estimate that it could translate into 800 million tons of electronic waste. E-waste. Electronic waste is a threat to the environment. According to the WHOincorrect disposal of this type of product can release up to 1,000 chemicals, many of them toxic such as lead or mercury. Extending the useful life of electronic devices has become a central issue in the environmental debate, which has prompted the creation of laws such as the right to repair, already in force in the European Union. Half solutions. Microsoft’s solution was for us to pay 30 euros to continue receiving security updates. A few days ago, the company launched a lifeline to users who want to continue using Windows 10 extending security patches for another year, although it had small print. In Europe it is relatively easy to do it, but in the United States it is more complicated because it requires using Windows Backup or use 1,000 program points Microsoft Rewards. The easiest way to secure your computers is to upgrade to Windows 11. The problem is that there are certain technical requirements and many computers do not meet them, although There are methods to install it anyway. Easy targets. There is another problem and that is security. we all remember the Wannacry ransomware disaster in 2017. It impacted numerous companies globally and had its origin in a vulnerability in older versions of Windows, specifically Windows XP and Windows Server 2003. The end of security updates leaves millions of Windows 10 users vulnerable to attacks like this.

Windows 10 is as of today an insecure operating system. One that is installed on 4 out of every 10 computers in the world

by

Today is the last day that Windows 10 will be officially supported by Microsoft. This means that this operating system will no longer receive security updates, and therefore the computers governed by said version will be exposed to security vulnerabilities that are discovered from now on. Windows 10 is too popular. The problem with this operating system going unsupported is that it is still enormously popular. It is true that Windows 11 has already managed to surpass it in share, but not by much. According to data from Statcounter GlobalStatsIn September 2025, Windows 11 has a 48.94% market share in Windows computers globally, while Windows 10 has a 40.5% share. Four out of ten Windows-based computers will use an insecure operating system. Five, without taking into account that one in ten continue to use even older versions: Windows 7 is installed on 9.61% of Windows computers, for example. Windows 11 is the version of Windows with the largest market share, but not by much. It overtook Windows 10 just a few months ago, and today Windows 10’s share is around 40%. Source: Statcounter GlobalStats. Remembering Wannacry. On May 12, 2017, we woke up to the news of a massive cyber attack that we first believed was had affected Telefónica and that it was actually global. The ransomware responsible for the attack, called WannaCryput companies in check from all over the world. The attack took advantage of a vulnerability called EternalBlue present in several old versions of Windows, including Windows XP, which at that time had a reduced market share (5%) but was relevant: it was still relatively used in companies that were exposed. The attack forced Microsoft to release a specific patch for this operating system, and showed how serious it can be rely on an insecure operating system. Payment lifeguard… To mitigate the problem that millions of users will now face, Microsoft offers two paths. One of them is the paying officer. The company has launched calls extended security updates (ESU, for its acronym in English). Although some requirements must be met (such as using Windows 10 22H2), many users can enroll in this program to continue receiving critical security updates. That, according to Microsoft, will allow time “while they make the transition to Windows 11”, which is the ideal solution for all Windows 10 users. This option is designed for business users but be careful, because said program – which in fact will have a total extension of three years – it’s not cheap: It costs $61 per device for the first year, $122 for the second, and $244 for the third. And entering the program later does not reduce the cost. …and free lifeguard. But Microsoft will also offer one more year of free security updates in Europe and the USA. In fact, in Europe, being able to activate that one-year extension of support for Windows 10 is relatively simple: just log in with a Microsoft account to access that option. It is best that you move to Windows 11. But obviously the best solution to avoid problems is to update your computer to Windows 11. It is possible to perform this update for free on Windows 10 computers according to Microsoft’s FAQ. Normally Microsoft requires that the PC or laptop meet certain requirements, but even in those cases it is possible to “skip” those obligations and install a modified Windows 11 with a little trick. Or give Linux a chance. There are other solutions, of course. One of them is to maintain the current equipment, but install some Linux distribution on it. Although that may put some users off, these distributions have been making it really easy for users to do the same things they do on their Windows computers for some time now. Including video gamessomething that Steam’s Proton platform has made possible. There is joy in the sale of PCs. In the third quarter of 2025, 9.4% more PCs were sold worldwide than in the same period of 2024. Source: IDC. The end of Windows 10 is a joy for PC manufacturers. Especially because this is the perfect excuse to change teams, especially in the business segment. Old PCs with Windows 10 are a huge security risk for these companies, which are especially forced to update their equipment or renew their IT fleet. That is also true for many users who take advantage of this circumstance, and that is causing a boost in sales. We are already seeing it: an analysis from the consulting firm IDC shows how in the third quarter of 2025, 9.4% more PCs were distributed than in the same period of 2024.
