It already has quantum weapons that it is testing in real missions

by

The research, weapons and defense departments of the main powers are a black hole. We cannot know what is on the other side, unless we They are the ones who allow us to take a look. It makes sense, since announcing a technology hastily would alert the rival. In this context, China has just taken a step in the war of the future: quantum war. We are very used to talking about traditional computing, and that of cyberwar It is an easy concept to understand. Hacker attacks on critical enemy systemsforms of make your troops invisible to rival radars or cyberespionage are concepts that have become everyday in current conflicts. And the future lies in quantum weapons. The quantum computing It’s not an incremental improvement in a computer’s processing speed: it’s a breakthrough. It is a paradigm shift and that is why researchers are developing these quantum computers which, in essence, allow solve complex operations in much less time than a classic computer. It is not easy, since although important steps have been taken in recent years, it still has challenges to solve so that your results are optimal. In a war and security context, and in a nutshell, this translates into one thing: if it takes a conventional computer hours or days to breach an enemy’s security, a quantum computer It would take minutes or seconds. And China not only says They are not only developing a dozen quantum warfare tools, but are already testing them in combat. “To design a good weapon, you have to think about what the war of the future will be like” As they point out in South China Morning Postthe People’s Liberation Army confirmed through the official newspaper Science and Technology Daily that they have more than ten experimental quantum cyber warfare tools in development. As we say, some of them are being “tested in frontline missions”, ‘capturing’ intelligence that can be used in the future. This is a project led by the National University of Defense Technology and, according to the report, focuses on three areas: Cloud computing. Artificial intelligence. Quantum technology. The fact that they are already testing some of these systems implies that they have left the theoretical framework, and the Army points out that “speed” is the main advantage that these tools offer. It is not just about making smarter weapons, but about giving more tools to those who analyze the situation. For example, quantum computing allows process large amounts of battlefield data in a matter of seconds. This implies that analysts can help make decisions practically in real time. They can also help in terms of both cybersecurity and cyberespionage, better protecting themselves with artificial intelligence systems that rewrite their code in real time – something we already see with malware such as PromtLock– or busting enemy crypto security faster. Related to this, they can help make GPS navigation systems more resistant to jamming or spoofing attacks. Or even perform navigation and positioning based on quantum sensors without depending on vulnerable infrastructure such as GPS or Starlink. It looks kind of steampunk, but this is part of a quantum computer Really, the applications seem limitless when we consider what has already been achieved with classical computing. These technologies also have potential to improve defenses aerial and detection of stealth aircraft, something in which United States with its F-35 and China with its J-36 They are investing a fortune. As they have commented in the magazine, the development of this technology responds to the need to think “what the war of the future will be like”, and how the war in Ukraine and Russian cyberattacks are showing uscyberwar will be the protagonist. They are, in short, tools that allow a conflict to end before the rival knows that it has started. It is the same philosophy that led to the development of the American F-35 fighter and a form of asymmetric warfare. Ok, very good, but what time advantage are we talking about? An example is the Google Sycamorea quantum computer that performed a calculation that would have taken a classical supercomputer 10,000 years in just… 200 seconds. In 2020, China already complete in another 200 seconds an operation that would have taken a supercomputer more than 2.5 billion years. Are they the only ones? Not even close. For Putin, the race for quantum computing is like the nuclear race after the end of World War II If there are hackers with a good reputation, they are the Russians, and the country is already testing prototypes such as quantum supercomputers Lomonosov Moscow State University with 72 qubits and another 70 qubits of the Lebedev Institute. Europe is also immersed in the era of the ‘Transition to Post-Quantum Cryptography’ in matters of defense of critical infrastructure (energy, finance, health or telecommunications) with the objective of having operational systems by 2030. Japan is also in itand the United States has high the budget for research and development of quantum systems from 141,000 million in 2024 to more than 179,000 million dollars (part of a total of almost a billion engaged for general defense). They have an advantage: IBM and Google are leaders in quantum systems maturitybut China is estimated to be closing the gap. And they must be confident in the possibilities of their systems if they already talk about them openly.

give a twist to Quantum Dots

by

TCL has been one of the leading proponents of democratization of MiniLED panelstechnology that it has carried to its entire range from 2025. Therefore, it has not surprised anyone that in 2026 it maintains its commitment to this technology. However, your proposal is different from Samsung either Hisense that are committed to changing the backlight matrix with Micro LED RGB systems. TCL has presented at CES 2026 a new technology called SQD-MiniLED that promises to change the landscape of high-end televisions. The proposal consists of combining the Mini blue LEDs with improved quantum dots to maintain brightness. that Mini LED screens provideapproaching the color purity of OLEDs. SQD-MiniLED: Vitaminized Quantum Dots by TCL TCL’s new technology focuses on the quantum dot filter responsible for breaking down and filtering the white or blue light emitted by the MiniLED diode array. The SQD that has been added to the name of this technology refers to Super Quantum Dot (or super quantum dots), the filter that contains the Super QLED Crystalswhich represent an evolution in the performance of the QD filters used in their televisions today. As the brand explained, the improvement in color volume of this technology is notable. Conventional MiniLED televisions reach approximately 83% of the BT.2020 color space, while the new X11L SQD, the only TCL television that will mount this new system, promises cover 100% of BT.2020. That means purer colors and a more complete visual palette. In addition, the new light filter is complemented by a new UltraColor filter with ultrafine particles (5 nanometers) that carries out a second filtering pixel by pixel, thus avoiding color interference and reducing the effect blooming (that halo that appears around bright objects on dark backgrounds, like subtitles). More dimming zones, more light control However, the development of the SQD filter for MiniLED is not the only improvement that TCL proposes to improve the image quality of its future televisions. Most high-end MiniLEDs offer between 1,000 and 5,000 local dimming zones, which is not bad at all. The X11L SQD, on the other hand, multiplies that figure up to 20,736 dimming zones for the 98 inch model. This increase is also supported by a 26-bit backlight controller capable of managing millions of control points, what TCL calls Precise Dimming Series. This combination is important because more dimming zones mean tighter control over which parts of the screen should brighten and which should remain dark. When you view a scene with stars against a night sky, that granular control allows the stars to shine without the glare spreading to dark areas. This is what allows us to combine deep blacks similar to those of an OLED, with peaks of extremely high brightness. The X11L SQD that TCL has presented as a test table for its latest technologies reaches the 10,000 nits maximum brightnessthe upper limit allowed by the Dolby Vision HDR standard. The combination of 20,736 dimming zones, together with 10,000 nits of brightness and 100% BT.2020 coverage, results in blacks controlled with extreme precision and a wider color volume than those currently offered by conventional MiniLED televisions. However, improving the panel’s performance does not imply an improvement in itself if that improvement is not well managed. Hence TCL has developed the new TSR AI processor with Super Resolution to manage the new capabilities of your SQD Mini LED panel by applying AI algorithms. The TCL will arrive soon to the United States and will start at $6,999 for the 75-inch models, increasing to $7,999 for the 85-inch version and $9,999 for the 98-inch ones. The brand has not confirmed its arrival in Europe and Spain, nor its price for the old continent.

A 600 kilometer quantum network is one of its great strategic bets

by

During the 90s the idea was established that Japan represented the future. Whoever traveled there found bullet trains, cities covered in neon, technological culture on every corner and a very visible contrast between tradition and innovation. In the early 2000s, cell phones with cameras and humanoid robots arrived, further reinforcing that image of a country ahead of its time. Three decades later, that perception is still alive in the collective imagination, but it no longer fully reflects the Japanese technological reality. Japan retains important capabilities, but has been losing ground for years. It controlled nearly 50% of global semiconductor production four decades ago and in 2019 it represented only 10%. In artificial intelligence fell from fourth to ninth place after the release of ChatGPT in 2022. According to the Global Innovation Index 2025 It occupies 12th place, and in digital competitiveness it falls to 31st, affected by a lack of specialized talent. Japan seems determined to return to the global technology board Japan is deploying several initiatives to reposition itself technologically, and one of the most relevant is its future national quantum network. The plan contemplates a 600 kilometer fiber optic infrastructure which will connect Tokyo, Nagoya, Osaka and Kobe, and will have an operational environment for testing in 2027. The National Institute of Information and Communications Technologies will lead the project together with Toshiba, NEC and telecommunications providers. The network will transmit quantum keys using photons, in states that allow attempts to intercept information to be detected. The quantum bet cannot be understood without considering the risk that comes. IBM and Xanadu They predict that quantum computers with bug fixes will be functional before 2030, which could render current encryption systems, including RSA and elliptic curve algorithms, obsolete. In 2024, researchers from Shanghai University breached SPN encryption using D-Wave technology, while Google warned that 2,048-bit RSA keys could be decrypted in less than a week with advanced quantum resources. That’s why NIST has begun publishing post-quantum cryptography standards to protect digital infrastructure. Building the network is just the first step. Japan has experience in quantum research, but lacks large-scale operating environments and will need to resolve issues such as signal stability, deployment costs and system governance. Equipment installed will be needed every so often to maintain the range and quality of the encryption, which makes the operation more expensive and requires specialized personnel. However, These challenges also represent opportunities to develop new capabilities, train talent and demonstrate that the country can compete again in advanced infrastructures. The international map shows that Japan is not starting from zero, but it is not leading either. China has a quantum network land of more than 10,000 kilometers that connects around 80 cities, and the European Union is working in its own infrastructure that covers several countries. The difference is in the approach: Japan aspires for its network to function as an operational national infrastructure, with the capacity to scale and become a strategic asset. The potential of this project goes beyond its technical scope. Japan seeks for this network to become a symbol of technological autonomy and a platform from which to build international agreements. With its own technology and operational experiencecould offer solutions to other countries and reinforce its role as a digital security provider. In a scenario where secure communications will be considered critical infrastructure, being prepared can be a way to regain relevance without competing in all sectors at the same time.

The United States is offering millions of dollars to quantum companies. In exchange, he wants to keep a piece of each

by

The United States has opened a new stage in its industrial policy. This time it is not about aid without return or simple soft loans: Washington is offering millions of dollars to quantum companies in exchange for a share in its capital. The information comes from the Wall Street Journalwhich points out that the agreements seek more than just supporting promising companies. The message is clear: the Government wants to ensure a seat at the table for a technology that can reconfigure the economy and global power for decades to come. The initiative fits into a chain of recent decisions in which Washington has been deepening its presence in sectors considered strategic. The Government transformed almost 9,000 million dollars in previous aid to Intel in a participation close to 9.9% and obtained special rights in US Steel to oversee sensitive corporate decisions. He also supported MP Materials in the critical mineral chain. The signal is clear: when the sector is considered vital, Donald Trump’s White House seeks to stay on board. When public money also buys influence Conversations affect some of the most visible names of the American quantum ecosystem. According to the newspaper, companies such as IonQ, Rigetti Computing and D-Wave Quantum They are negotiating with the Department of Commerce the entry of the State into their capital. Other firms, including Quantum Computing Inc. and Atom Computing, are studying similar deals. Operations would start from a minimum of 10 million dollars per company in this initial phase, with the possibility of more applicants joining as the program progresses. The conditions are not limited to a mere public investment. The Commerce Department is studying formulas ranging from equity stakes to intellectual property licenses, royalties or revenue sharing schemes. The conversations are led by Paul Dabbarformer executive of the quantum sector and current number two in the department, according to published information. At this stage there are no closed agreements, but the approach indicates that the State seeks a tangible return and supervision tools. Washington’s interest is not explained only by financial reasons. Quantum computing is emerging as one of the technologies with the greatest capacity for industrial transformation. These machines promise to solve calculations that would take eons to current systemswith potential applications in fields such as drug design, advanced materials or highly complex chemistry. Adding to this momentum is international competition, with companies like IBM, Microsoft and Google involved and China advancing its own quantum race. The security dimension adds another layer of urgency. Quantum algorithms are projected to They may violate traditional encryption systemsincluding RSA and ECC, exposing both sensitive communications and critical infrastructure. The risk is not limited to the future: the strategy known as harvest now, decrypt later suggests that malicious actors are already collecting encrypted data for decryption when this capability becomes available. Given this scenario, Fortinet highlights the need to move towards post-quantum cryptography and strengthen networks and systems. The practical potential of this technology is well illustrated by the pharmaceutical sector. McKinsey highlights that quantum can transform drug development by enabling precise molecular simulations, something that classical calculus and pure AI fail to always capture. Large companies are already testing these systems to study proteins, evaluate chemical reactions or reduce experimental steps. This ability to model complex structures from scratch promises to accelerate research, improve the success rate in trials and shorten times to market for new therapies. The implementation of this approach is not limited to companies. According to the Wall Street Journal, the Commerce Department reorganized the office responsible for the scientific side of the CHIPS program and recovered several billion dollars that had been allocated to previous technology initiatives. The political message is transparent: the Executive wants public investments to be measurable and for the State to have mechanisms to benefit when the funded projects mature, especially in sectors with high strategic involvement. The shift raises dilemmas typical of a more interventionist model. Public participation can facilitate stability in strategic sectors, but it also opens the door to conflicts between technological, industrial or political priorities. The central doubt is to what extent the presence of the State will affect the pace of decision and the flexibility that the most competitive sectors demand. There are still relevant unknowns. The final percentages that the State could reach or the exact conditions that would accompany the participations are not known. According to the information available, the agreements are still in the negotiation phase and could be modified before being closed. It also remains to be seen what commitments will be required of companies and whether there will be associated performance or governance criteria. At this point, the process is moving forward, but a definitive schedule for awards or formalization of agreements has not yet been announced.

Google has solved problems in two hours that would take three years on a supercomputer. It’s the quantum advantage we needed

by

Google has taken a notable step into the field of quantum computing with a new algorithm called Quantom Echoes. This algorithm has been able to demonstrate for the first time a “practical and verifiable quantum advantage” that makes its quantum computer make fools of today’s large supercomputers. 13,000 times faster than a supercomputer. The new algorithm, called Quantum Echoes (“Quantum Echoes”), has made it possible to demonstrate that a quantum computer – based on Google’s Willow quantum chip— successfully executes a verifiable algorithm that exceeds the capacity of today’s large supercomputers. Thus, that computer managed to execute that algorithm 13,000 times faster than the best current classical supercomputer when executing similar code. “Quantum verifiability”. Google’s quantum supercomputer solved the problem in just over two hours, when in the second supercomputer most powerful in the world, Frontier, would have taken 3.2 years. But it also did it in a verifiable way: the result can be repeated in the quantum computer itself or in any other of similar caliber. Quantum echoes. The algorithm resembles an advanced echo: you send a signal to the quantum system, perturb a qubit, and then precisely reverse the evolution of the signal to “listen” to the resulting echo. This echo is special because it is amplified by constructive interference, a quantum phenomenon where waves add up to become stronger, which allows this effect to be precisely measured. The algorithm allows modeling the structure of systems in nature, from molecules to black holes. An achievement with a lot of Nobel Prize behind it. The milestone is based on decades of research in this area, including that carried out by the recent Nobel Prize winner, Michel H. Devoretwho is part of the Google team. Together with his colleagues John M. Martinis and John Clark he laid the foundations for this advance at the University of California at Berkeley in the mid-1980s. “Quantum verifiability”.

His discovery: the properties of quantum mechanics could also be observed in electrical circuits large enough to be seen with the naked eye. That gave rise to the creation of superconducting qubitswhich are the basic blocks with which Google has created (like other companies) its quantum computers. Devoret joined Google in 2023, thus strengthening the company’s trajectory in its search for the now famous “quantum supremacy”. Promising practical applications. The advance is directed directly to the solution of important problems in fields such as medicine or materials science. Quantum computing remains an experimental technology and faces a key challenge with error correction, but Quantum Echoes demonstrates that “quantum software” is advancing at a pace parallel to hardware. Google applied Quantum Echoes to a proof of concept experiment for Nuclear Magnetic Resonance. This technique acts as a “molecular microscope”, a powerful tool that will help design drugs or, for example, establish the molecular structure of new polymers. a marathon. This new milestone demonstrates the progress that this technology has made in recent years, but Google is not alone here. Microsoft or IBM have also made notable advances in recent years, and of course there are numerous startups both in the US like in china who work in this area.

40 years ago three researchers insisted on blurring the borders of quantum physics, today they have won the Nobel

by

It was 1935 and Erwin Schrödinger was already tired of reading nonsense. It was not a decade since the birth of modern quantum mechanics, but the world had already filled with delusional pseudophilosophical reflections on what reality really was. It was then that poor Erwin inflated his noses and decided to talk to us about his cat. The happy cat of Schrödinger. Of his cat, of a closed opaque box and, in addition, of a container with a poisonous gas. The container in question is controlled by an opening device that only works if a radioactive particle disintegrates over a certain period of time. After that period, the probability that the cat is dead is 50% and that it is also alive of 50%. “If we do not open the box,” the standard version of this ‘paradox’ tells us, “the cat will be alive and dead at the same time.” Or, in other words, we could be calm: as long as we did not open the box, the cat would not be really dead. According to many interpreters, in fact, it would be the one that opens the box that kills the cat. No one understands poor Erwin. The interesting thing about all this is that, although it has been used to the fed up to illustrate The idea of ​​quantum overlapSchrödinger used it to demonstrate how absurd it was to apply categories of quantum mechanics to the real world (macroscopic). For the Austrian physicist, the happy cat would be alive or dead regardless of the opening of the box or not. But … what if not? However, half a century after all this, there were a group of researchers from the University of Berkeley who did not have it so clear. For some years it was known that we were missing a key piece to understand the process of molecular disintegration. That is, “the ability of individual particles to disintegrate is well known” (this is, for example, the physical fact that there is Behind carbon-14); What happens is that according to what we knew about physics, that could not be. The particles should not disintegrate. Between 1984 and 1985, John Clarke, Michel H. Devoret and John M. Martinis They performed a series of experiments With a closed electrical circuit with superconductors and showed that, well, Schrödinger was wrong. How was it wrong? As I say, the intention of the cat’s mental experiment was “to demonstrate the absurdity of this situation, since the special properties of quantum mechanics usually disappear on a macroscopic scale. The quantum properties of a complete cat cannot be demonstrated in a laboratory experiment.” However, since these researchers were successful in demonstrating that the very strange properties of the quantum world can also be seen in a larger system, none of this is so clear. This explains very well people like Anthony Leggett Because, although “a macroscopic system composed of numerous pairs of Cooper remains many orders of magnitude smaller than a kitten”, the key of the experiment is that “there are phenomena that involve a large number of particles that, together, behave as they predict quantum mechanics.” A Nobel to kill a cat. “It would surprise you very much if the ball suddenly appeared on the other side of the wall. In quantum mechanics, this type of phenomenon is called a tunnel effect and is precisely the type of phenomenon that has given it the reputation of being strange and not very intuitive,” explained the award committee. That is precisely what these researchers showed that it could happen at the macroscopic level. But they did something else. And I do not mean to lay the foundations that have allowed us to create the technological system we know: from the transistors of the computer microchips that we see everywhere to quantum cryptography. No. I mean blurring the wall that separated the world from the very small with the world we know. Along the way, “they killed a cat”; But because of the gap they opened, one of the best science we have was sneaked.

Physicists believed that the neglect was a useless particle. Now they suspect that it is the key to universal quantum computers

by

Experts Quantum computing with those who have had the opportunity to speak, such as Spanish physicists Ignacio Cirac either Juan José García RipollThey argue that quantum computers will be able to make great contributions when they are capable of amend your own mistakes. The main problem they face in this area 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 to identify real -time errors and correct them. The problem is that from a practical point of view This strategy is very challenging. Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Anyway, the researchers will have one more tool to deal with the errors of quantum computers. It can even be the most powerful resource that they currently have at your fingertips: the Neglectón. Universal quantum computers are one step closer One of the most promising research fields in this area is topological quantum computing. Its purpose is to protect the delicate quantum information that the cubits work coding it in the geometric properties of exotic particles known as ISING anions. An important note before moving forward: in condensed physics an anion is not the same as in chemistry. In fact, Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials. Its existence has not yet been demonstrated experimentally, so they are a theoretical result at the moment. It seems a complicated concept, and it is, but in this article we do not need to deepen much more. What we do need is that Ising’s anions They are presumably much more robustand, therefore, resistant to errors that traditional cubits. In practice this implies that moving some anions around others in a specific way should allow researchers to carry out logical operations with them. This is the reason why they are so attractive in quantum computing. And, in addition, they have another great advantage: this configuration is largely immune to external noise. Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials Currently, Ising’s anions are thoroughly investigating in the condensed matter laboratories of the entire planet because they are one of the main candidates to participate in the construction of universal quantum computers, and, therefore, immune to errors. Aaron Lauda, ​​professor of mathematics, physics and astronomy at the University of Southern California (USA), Holds the following: “By themselves, Ising’s anions cannot perform all the necessary operations for a general purpose quantum computer. The calculations they support are based on the ‘braided’ (branding), And they require physically moving anions around each other To carry out quantum logic. For Ising’s anions, this braided only allows a limited set of operations known as Clifford doors, which fall short with respect to all the power required for universal quantum computing. “ Fortunately, the research team led by Lauda has found a way to transform ISING anions into universal structures that are capable of performing any quantum calculation through braided. Its solution for the moment is only theoretical, but its potential is enormous. The surprising thing is that what they propose is to resort to a new type of anion known as Neglectón that was initially discarded when it was “discovered” in the theoretical framework. In fact, Neglelectón has gone from being a mathematical waste to be the new hope of quantum computers. In theory when combining Ising’s anions and neglect, universal quantum computing will be possible through braided. According to Aaron Lauda Only one neglect is needed because it remains in the stationary or static state while the calculations are carried out by braiding Ising anions around them. It is a surprising conclusion. One last note to conclude: The neglect is not a fundamental particlesuch as the electron or the quark; It is a theoretical quasiparticle that arises from the collective behavior of many other particles in a two -dimensional system. Let us trust that it is consolidated as the definitive tool that will allow researchers to carry quantum computing from theory to practice in a robust and efficient way.

Quantum computers will change the world when they don’t make mistakes. This milestone is closer thanks to quantum gravity

Some experts believe that all the effort that is being carried out in the field of Quantum computing Not anywhere. One of the members of the scientific community more critical of quantum computers is the Israeli mathematician Gil KalaiProfessor at Yale University. 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. However, the absence of unanimous support by the scientific community should not tarnish the notable effort and advances that many research groups are doing, some of them in Spanish institutions such as the CSIC and others integrated into the structure of companies that have very bulky resources, such as IBM, Google or Intel, among others. In fact, as expected, the latter defend that the long -awaited error correction will reach quantum computers and will allow them to face a much broader fan of problems than that of current prototypes. Terra Quantum bets on quantum severity to correct errors 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 to identify real -time errors and correct them. The problem is that from a practical point of view this strategy is very challenging. QMM technology reduces errors by up to 35% in current quantum processors Logical cubits represent a way to overcome the difficulty of the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. The error correction strategy proposed by the researchers of the Swiss Terra Quantum company is not an alternative to the solutions in which we have just inquired; It is a complement. In fact, as explained in the article they have published in Advanced Quantum Technologiesits QMM technology (Quantum Memory Matrix) Reduce errors by up to 35% in current quantum processors. And, in addition, it reaches 94% fidelity using ten times less cubits than conventional methods. An important note: Terra Quantum’s scientific article has been reviewed by pairs. Terra Quantum has tested its QMM technology in IBM superconductor processors, and works. It only requires adding a quantum circuit that does not alter the architecture of the processor, although it is very ingenious. In fact, its operation is inspired by A principle of quantum gravity which maintains that the space-time continuum can be described as a network of me memory cells. It is a complicated idea, it is true, but the really important thing is that we know that this theoretical concept is the one that has inspired Terra Quantum scientists the design of their quantum circuit of errors suppression. Anyway, this innovation joins the effort that IBM, the MIT and other organizations are making to invite us to tie the future of quantum computers with a very reasonable optimism.

In 2030 he plans to have the most powerful quantum computer that exists

China and the US are the countries that are dedicating more resources to the development of Quantum technologies. And also those who are reaching The most relevant achievements. However, there is a country that has officialized its intention to lead in the medium term both in the field of Quantum computing as in the manufacture of semiconductors: Japan. In the middle of last April we tell you that the Riken Center for Quantum Computing and Fujitsu had just announced that they had developed in a joint project A superconductor quantum computer endowed with 256 cubits. A priori may not seem like a great achievement if we are in mind that IBM already has a condora superconductor quantum processor of 1,121 cubits, and also The Heron platform (5k) endowed with error mitigation. And the China Telecom Quantum Group (CTQG) and the Center for Excellence in Quantum Information and Quantum Physics of the Chinese Academy of Sciences have developed The Xiaohong quantum processor of 504 superconductor cubits. However, Japan’s plan in the field of quantum machines does not end up here. And it is that in 2030 it intends to have a quantum computer 25% more powerful that the most capable that IBM will have at that time. 250 logical cubits to make a difference The design and tuning project of this ambitious quantum machine is already underway. And the Riken Center for Quantum Computing, Fujitsu and the National Institute of Advanced Industrial Science in Japan. This quantum computer will use superconductor cubits and a very advanced cooling system, presumably a dilution system similar to the employee by The machine they presented in April. Whatever your best asset, if you finally get to fruition, it will be its 250 logical cubits. Each logical ul Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed in an abstract way About several physical or hardware cubitsso that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Until very recently the number of hardware cubits that was necessary to implement a single logical cubit immune to errors was impracticable, but IBM says that he has found the solution To this problem. And presumably Fujitsu and the Riken center too. IBM is going to build The quantum computer ‘Starling’ in a new data center that will be housed in Paughkeepsie, New York (USA). This machine will bring together 200 logical cubits that, in theory, will allow you to execute 100 million quantum operations. IBM says that ‘Starling’ will be ready in 2029but, as I mentioned a few lines above, Fujitsu and Riken intend to have their quantum machine of 250 logical cubits in 2030. If they get it, they are likely to lead in this field. In any case, before that milestone arrives, much earlier, in 2026, they pursue to be ready A 1,000 cubits computer. They will not be 1,000 logical cubits; They will be 1,000 conventional cubits, and, therefore, prone to make mistakes. Even so, if Japan get it, only one step from the US and China will be placed in this field.

Airplanes have been depending on GPS for decades. Some engineers have another idea to replace it: quantum technology

by

Airbus and the company derived from Google focused on quantum technology and IA, Sandboxaq, have completed more than 150 flight hours Testing Magnava revolutionary system that uses Quantum sensors to detect the unique magnetic “fingerprints” of each point on the earth. The initial results have been promising, and are a sign that technology could rival the Traditional GPS and even overcome it in precision. Why is it relevant. The GPS has become the Achilles heel of modern aviation. Interference attacks and Spoofing They are dramatically increasing in conflicting areas such as the Middle East, Ukraine and Russia, and this It also affects civil flights. The military use these techniques to confuse missiles and drones, but the consequences extend dangerously to commercial aviation. Hence the importance of looking for a viable alternative to GPS. Magnav. Image: Sandboxaq The secret of its operation. Magnav has more or less the size of a toaster, and has a laser that shoots photons against electrons. When the laser goes out, these electrons release the absorbed photons with a unique energy firm that reflects the intensity of the earth’s magnetic field in that exact location. An artificial intelligence algorithm processes this information and compares it with detailed magnetic maps to determine the position of the plane. Each square meter of the planet has an unrepeatable magnetic firm, created by the iron particles of the earth’s core that magnetize the minerals of the cortex. More precision and more difficult to supplant. Unlike GPS, which depends on vulnerable digital signals from satellites, quantum sensors are completely analog and process data generated entirely on board. Jack Hidary, CEO of Sandboxaq, Explain that this makes them “essentially impossible to interfere or supplant.” During the evidence, Magnav managed to meet the standards of the Federal American Aviation Administration 100% of the time, maintaining precision within 2 nautical miles. Even more impressive, it reached a 550 -meter accuracy in 64% of the occasions. Beyond aircraft. The experts They predict A quantum sensor market valued between 1,000 and 6,000 million dollars by 2040. This technology promises to detect submarines and hidden tunnels in defensive applications, and weak magnetic signs of the heart and brain in medicine, allowing non -invasive diagnoses. Joe Depa, Global Innovation Director of EY, Underline That “we are not talking about something within 20 years, but about something that is here and now.” The next step. Sandboxaq plans to go first to the defense sector before expanding to commercial flights. Although more evidence and certifications are required, Hidary stands out that have overcome “the difficult part: demonstrate that technology works.” According to him, it is the “first novel absolute navigation system that we know in the last 50 years.” Cover image | Ross Parmly In Xataka | The 777x is Boeing’s great bet to return to the top: folding wings, redesign cabin and the largest engine in the world
