Bitcoin encryption and other cryptocurrencies will fall. And those responsible will be quantum computers

by

Experts Quantum computing They have known for several years that quantum computers will end classical cryptography. One of them, Juan José García Ripoll, a researcher at the Institute of Fundamental Physics of the Higher Council for Scientific Research (CSIC) who develops his research activity within the quantum information group and foundations of quantum theory, He warned us During the conversation we had with him in October 2019. That moment arrived in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a D-Wave quantum computer for I successfully violate the SPN encryption (Substitation-Permutation Network), which is a cryptographic algorithm that is 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 result of their research in An interesting article entitled “Public Cryptographic Attack Algorithm based on quantum processing with the advantage of D-Wave”. Interestingly, Professor Wang Chao and his team used two strategies to carry out their attack on cryptographic algorithms. The first one consists of broad strokes to deliver to the quantum computer the combination of an optimization problem and another search. Quantum machines are very effective when solving these challenges. And the second strategy consists in combining Schnorr’s algorithm, Babai rounding and a quantum method of optimization. In any case, the most interesting thing is that these Chinese scientists concluded that AES-256 and other military degree encryption algorithms are closer than ever to be violated. Google says that quantum machines will break the encryption of cryptocurrencies During my conversation with Juan José García Ripoll I did not let the opportunity to ask what would happen when quantum computers were able to violate the most advanced encryption technologies we currently use. “In principle, quantum computers will make the encryption algorithms that we use. For this reason there is a research area in mathematics and cryptography: cryptography resistant to quantum computers. It is a very difficult field of work. The alternative to the fact that many codes can break with quantum computers is to use quantum systems for cryptography,” Ripoll holds. An RSA integer of 2,048 bits can be factor in less than a week with a quantum computer of less than one million cubits The course of time has proved him right. And it is that several Google researchers less than a week ago They published an entry In the blog dedicated to the security of this American company in which they support a crucial premise: an integer RSA (Rivest – Shamir – Adleman) of 2,048 bits can factor in less than a week with a quantum computer of less than one million cubits. One of the most advanced quantum processors that currently exist, IBM Condor Chipagglutina 1,121 superconductor cubits, so it is evident that we still do not have quantum machines with the necessary power to violate RSA encryption. However, they could be ready before we suspect. The quantum machine described by Google researchers use noisy cubits, and IBM’s official itinerary argues that ‘Starling’, its first quantum hardware endowed with the ability to correct their own mistakes, It will arrive in 2029. Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptical 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 Google scientists signed by the article that I have mentioned above, if the future quantum computers will cost them less than initially breaking the RSA encryption, the cryptography of elliptical curve will also fall with relative ease. It is still not clear What capabilities will have to have quantum machines which will be able to violate this encryption technique, but According to a research group from Kent University (United Kingdom), Bitcoin can update the encryption of the entire network without “turning it off” in approximately ten months.

Elon Musk got outstanding in computer science. Who designed the computers they used did not approve with the same ease

by

Become one of the greatest fortunes in the history of humanity Obviously it requires certain skills, especially when that fortune has been obtained in The technology sector. Who stands out in the technological field, tends to qualify as “technology geniuses.” Elon Musk, for example, obtained excellent notes in complicated matters as computer science. Paradoxically, Steve Jobs and Bill Gates, the most relevant names in the development of the computers that Musk used in their classes, did not stand out For your good notes During your student stage. His intelligence had a lot to do with it. Steve Jobs, the approved scraping A psychological report Prepared by the FBI on the student profile of Steve Jobs revealed that Apple’s co -founder had an average grade (GPA per grade point avenge) in secondary school of 2.65, which is equivalent to obtaining school grades between C and B. which could be considered as a scraping approved. However, despite obtaining such tight qualifications, the report He pointed outthat Jobs was extremely intelligent and with an exceptional ability to mold people of its environment manipulating truth and reality to achieve its objectives. When Jobs Fundo Apple, Those skills They served to attract the best talent by his side and convince them that they were able to design the best products in the world. Bill Gates, scattered talent In his autobiographical book, ‘Code Source: My beginnings’Gates reveals that during his high school in the exclusive Lakesid school he obtained grades that did not adjust to those of a preteen with the ability to quickly learn the complicated mathematical concepts that read in the books. “He was an avid generalist in a place where people focused on concrete matters. He didn’t fit, in summary, and he didn’t know how to solve it. So I pretended he didn’t want to do it.” The millionaire recognized that, although he was able to learn the subjects before his classmates, his attitude and behavior in class and with the rest of the students it was not adequate, and he did not feel motivated by the issues studied in class. However, all that changed when he discovered that he could create programs with the teletype of the “computer room.” Gates acknowledged that this moment marked a before and after in his passage through Secondary. He managed to focus And his notes improved immediately. ELON MUSK: Bright computer notes Elon Musk is the exception confirming the rule. A few weeks ago, Maye Musk, mother of the richest person on the planet With an estimated fortune of 419.6 billion dollars, he published in Your X profile An unpublished document: Elon Musk’s computer notes. Touch the image to go to the original message In his message, Maye Musk explained that, while reviewing his old family photos, he found a notification of the computer notes of the University of Pretoria of his son Elon Musk when he was 17 years old. “My genius child. Mom proud,” wrote the mother of the millionaire. In its qualifications it can be seen that the South African millionaire obtained the maximum score (A+) in programming and computer use skills. In response to his mother’s message, Musk said: “They told me that I obtained the highest score in engineering aptitude they have ever seen.” In other words, not bad for a human, as a future AI would say. “ High capabilities, low grades. The bad academic results – especially in the pre -university stages – of many of the people who have subsequently been considered “technological geniuses”, are not casual. The Scientific literature In this regard It is extensive and points to the existence of a link between the people with high capacitiesintellectuals with a Low school performance. Data from the Ministry of Education and Science estimated that around 70% of students with high capacities registered low school performance. The main reason for school failure among these students with high capacities is the lack of motivation to follow the rhythm of the classes. This, as Gates said in his book, It generates dispersion And his curiosity was aimed at learning on other issues that had nothing to do with the subject he had to study. On the other hand, the social factor and Its integration with the rest of the students It is also a key component for school success in these cases.

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.

Japan has just been put in the career of quantum computers. And he has done it with his own technology

by

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, no advanced country can afford to remain out of a technology with An indisputable rupturist potential in the medium term. In this field Japan is adopting a discreet position, but its contributions, although they are not as numerous as those of the other two countries that I have mentioned in this paragraph, are also very important. In 2023 a group of researchers from the Riken Center for Quantum Computing, in Japan, led by Professor Keisuke Fujii He devised a very advanced algorithm which dramatically reduces the computational complexity of some quantum procedures. His work was published in the scientific journal Physical Reviewand even today is the best available tool to efficiently reproduce the atomic level interactions that take place in some complex materials. The protocol designed by these Japanese scientists manages to deal with temporary evolution operators in a much more efficient way than the technique used so far, which is known as trotterization. In broad strokes these operators are numbers matrices that describe the very complex interactions that take place in quantum materials. In addition, the algorithm devised by Fujii and his colleagues is a hybrid solution that combines quantum and classic protocols, and has the ability to allow relatively simple quantum computers, such as those we have now, face very complicated problems. The Riken and Fujitsu center have made a quantum computer of 256 cubits Today, just a few hours ago, the Riken Center for Quantum Computing and Fujitsu They have announced which have developed in a joint project a superconductor quantum computer equipped 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. One of the most attractive assets of this quantum computer is that it allows efficient to scale the number of cubits However, the implementation of this Japanese machine deserves to be considered an undoubted success if we take into account that it uses technologies developed entirely in Japan. It does not use the hardware designed by IBM or Intel, which is what some research centers disseminated by Europe have done. One of the most attractive tricks of this Japanese quantum computer is that it allows Efficient scalar the cubits number No need to completely redesign all the architecture of the machine. In addition, the dilution cooling system used is, according to Fujitsu, more efficient than the solutions usually used in other quantum computers. This statement is credible because this 256 cubits machine works properly with the same cooling unit as the previous 64 -cubites quantum computer of the Riken center. It sounds very good. However, this is not all. The plan of the creators of this quantum machine is to have a computer of 1,000 cubits ready in 2026. If Japan get it, it will be placed in this field just one step from the US and China.

After triumphing with its chips for AI, Nvidia has set another disruptive technology: quantum computers

by

Nvidia’s bet for Quantum computers It is less and less shy. Jensen Huang, the co -founder and general director of this company, has announced A few hours ago at its annual developer conference that will open a laboratory expressly dedicated to Quantum computing research. It will be housed in Boston (Massachusetts) and will allow NVIDIA engineers to work side by side with the researchers at Harvard University and the Massachusetts Technology Institute (MIT). It will begin operating at the end of 2025. This strategic movement puts on the table with absolute clarity that Huang does not want to stay out of technology that will presumably cause a medium -term disruption. The most curious thing is that before formalizing the implementation of its new quantum technologies development laboratory, this executive has not let out the opportunity to retract. At the beginning of last January A few statements They caused a very abrupt fall of the actions of some of the companies that are dedicated to the development of quantum computers. “If you said 15 years you would probably be optimistic. And if you said 30 you would be pessimistic. But if you opt for 20 years I think many of us would believe it,” Jensen Huang argued At that time. With this reflection I tried to predict when the really useful quantum machines will be ready, and, therefore, capable of dealing with a very wide range of problems. But he has changed his mind. Just two and a half months later seems to be convinced that fully functional quantum computers will be ready much earlier. With the correction of errors of quantum computers in the spotlight Nvidia flirting with quantum computers is not really new. And is that He has been collaborating for more than two years With the Israeli company Quantum Machines. This company specialized in the development of hardware and software for quantum machines, and has been ready with NVIDIA a low -performance and high performance architecture that seeks to promote the progress of quantum computing. DGX quantum seeks to help researchers who work in the field of quantum computing to develop new quantum algorithms NVIDIA has contributed its CPU/GPU grace hopper system, a beast that is designed to execute applications of artificial intelligence and offer productivity at high performance computer scenarios, and also its open source programming model CUDA QUANTUM. His partner in this project, Quantum Machines, has been in charge of the integration and set -up of a quantum platform that, according to these two companies, is specifically designed to work in hybrid systems in which classical hardware and quantum coexist in harmony. The purpose of the DGX Quantum platform, which is what is called the hardware that these two companies have developed, is to help researchers who work in the field of quantum computing to develop new quantum algorithms. It may seem surprising that it is possible to use classic hardware to develop quantum algorithms, but it is something perfectly viable. In fact, this strategy helps to put quantum computing within the reach of many more researchers who can implement and test their ideas without having access to a quantum computer prototype. However, the DGX quantum platform also serves, according to NVIDIA, to calibrate quantum systems, control them, and even aspires to have a prominent role in the tuning of a correction system that allows quantum computers amend your own mistakes. Jensen Huang emphasized this idea during his GTC 2023 conference, and there is no doubt that It is a very attractive possibility. Extraordinarily attractive. And is that, As Ignacio Cirac explained to us In the conversation we had with him, the correction of errors will give us the opportunity to solve with quantum computers really significant problems.

Mathematicians needed 300 years to demonstrate Fermat’s last theorem. Computers have not achieved it

by

“I have found a really admirable demonstration, but the margin of the book is very small to put it.” It is what the 17th -century French mathematician Pierre de Fermat wrote when stating his His “last theorem”. Fermat’s problem took three decades to be found between the mathematician papers and three centuries until that admirable test was discovered. And yet the case is not entirely settled, only that the challenge is something different. Take it to a computer. He New challenge It is to make a computer to try the elusive theorem. That is the objective of a new project, FERMAT FORMALISINGled by Imperial College London. Fermat’s problem. Fermat’s last theorem “postulates that, if A, byc are natural numbers and not equal to zero, the an+bn = cn equation has no solution if n is greater than two. Formally demonstrating something is not as simple as trying it by rehearsal and error, and this demonstration, too complex for the “megish margin” of the Fermat’s notebook would be lost for centuries. The problem was resolved in 1994 by the British Andrew Wiles, who had begun to solve this puzzle with only 10 years. In 2016 Wiles was awarded the ABEL award, the award considered “The Nobel of Mathematics.” Almost one million pounds. Another 30 years after the resolution of the enigma and more than three centuries after the death of Fermat, a team of researchers, led by Kevin Buzzard, of Imperial College London, has put to work to take a different step, teach A computer to solve this problem. The new project It began at the end of 2024 and will last until 2029. It has a financing of just over 934,000 pounds and already begins to give some results, in the form of code fragments that are added to a Database in Github. What remains to be resolved.It can be contraintuitive, but this type of reasoning, which lead us to formally demonstrate mathematical theorems, are difficult to teach computers. Recently, Buzzard and other experts They explained the complexity of the matter to the French newspaper I monde. To begin with, we must take into account that the resolution of this theorem is complex, it is no accident that several generations of mathematics would turn the brains trying to find it. These mathematicians also had previous experience in the field of resolution of these types of problems. As Buzzard explained to the French newspaper, mathematicians have a base that allows them to “jump steps” when explaining the resolution to this problem. A computer, however, must start from scratch when building its own explanation for the matter. And all this, for what? “Fermat’s last theorem (…) has no applications, theoretical or practices, in the real world,” Buzzard pointed out A few months ago to the magazine New Scientist. So why so much effort to teach a computer to solve something we already resolved? The key here is not in the past but in the future. According to Explain the team at the head of the projectcomputers today can be used to attend mathematicians trying to solve problems such as demonstration of theorems, but there is an obstacle to materializing some forms of help. The problem, they point out, is that few mathematicians have focused on working with this software, so there are no tools that have the “definitions” used by mathematicians to solve these problems. Working on this problem should be used to create the necessary databases for solving similar problems in the future. In Xataka | We had more than a century trying to solve some mathematical problems.
