On October 26, the Global Times brought us good news: the superconducting quantum and optical quantum computer research project led by the Institute of Quantum Information and Quantum Science and Technology Innovation of the Chinese Academy of Sciences has made a major breakthrough. According to reports, these two quantum computers can perform complex operations of "quantum random line sampling". What is even more gratifying is that thanks to the superiority of quantum computing, China's quantum computer is ten million times faster than the most powerful traditional supercomputer at present when calculating problems of the same difficulty; in the same computing time, China's quantum computers can calculate a computational problem that is one million times more difficult than the famous "planewood" superconducting computer developed by Google in the United States. The Global Times commented that the success of this project is a milestone for China to achieve the superiority of quantum computing, and in the title of the article, it is prominently stated: China, the only one in the world!
In today's world, whether it is scientific research or social governance, a large amount of data is needed as a reference basis, and the larger and more data samples, the more reasonable and scientific the scientific conclusions and policies formulated. In terms of scientific research, scientists now often input some key data into supercomputers and let computers simulate experimental results, thus saving a lot of research funds and time. In social governance, taking our great battle against the new crown epidemic as an example, big data computing has provided great help for finding close contacts, which shows that the big data computing led by supercomputers is closely related to our lives.
But as scientific research becomes more in-depth and modern life becomes more exciting and complex, the data generated is exploding. However, the traditional supercomputer, because the chip process development is bottlenecked, Moore's law is rigid, etc., the performance improvement speed can not keep up with the world's demand for computing power. In this context, the development of new supercomputers and the improvement of data analysis efficiency have become the common pursuit of all mankind. Due to its unique physical advantages, quantum computers have computing power that traditional supercomputers cannot match. According to the "quantum hegemony theory" proposed by Google in the United States, the problem that the superconducting quantum computer can be calculated in two hundred seconds, and the traditional supercomputer needs a full 10,000 years to calculate it; and the amount of operation of the optical quantum computer in two hundred seconds takes the traditional supercomputer to calculate it for a full 2.5 billion years. It can be said that if anyone masters quantum computing technology, he or she will be able to obtain the forerunner of future economic, scientific, technological, and social development.
The prospects of quantum computers are bright, and their superiority is even more crushing of traditional supercomputers, but they also have insurmountable shortcomings, that is, huge investment and harsh use environments. Quantum computers are based on a new theoretical concept proposed by quantum mechanics, and quantum mechanics will only take effect in the microscopic world, which determines that quantum computers must invest huge amounts of money, time and equipment to operate normally. And take the "planewood" superconducting quantum computer developed by Google, which needs to reduce the ambient temperature to absolute zero, that is, minus 273.15 degrees Celsius to operate normally, such a complex machine is by no means affordable for ordinary countries. At present, there are only a few countries that still insist on studying quantum computers, such as China, the United States, Japan, the United Kingdom and the European Union, but only China and the United States have really made great breakthroughs.
Unlike Google in the United States, which will devote all its energy to superconducting quantum computers, China is also insisting on the development of optical quantum computers while developing superconducting quantum computers, and the experiment reported by the Global Times today proves that china's two quantum computers have achieved major success. Pan Jianwei, an academician of the Chinese Academy of Sciences, said that at present, China's quantum computer has achieved "quantum computing superiority", and what needs to be done next is to achieve quantum error correction in the next four to five years to further improve the accuracy of quantum computers. As long as quantum error correction is achieved, China can use quantum computers for the simulation of major scientific problems. It is no exaggeration to say that the success of the experiment of the Chinese Academy of Sciences has laid the foundation for China's world leading position in the field of quantum computing.
According to the research of scientists from all over the world, the current development process of quantum computers is roughly divided into three stages. The first stage is to develop a high-precision quantum computer with fifty to one hundred qubits, and then prove that the quantum computer has a powerful computing power that traditional supercomputers cannot match, and achieve "quantum computing superiority" or "quantum supremacy". The second stage is to manipulate the quantum system and develop a quantum computer with millions of qubits. The third stage is to improve the accuracy of the manipulation of the quantum, so that its calculation accuracy threshold exceeds 99.9%, and solve the problem of unstable operation of the quantum computer, which will eventually make it a quantum computing prototype that can be used normally. The major breakthrough made by the Chinese Academy of Sciences this time has made China the second country in the world to complete the first stage and move towards the second stage. Some commentators even believe that although the United States reached the first stage before China, the computing power of its computer is far behind that of China, and China is working together in the two fields of optical quantum computing and superconducting quantum computing, while the United States only adheres to superconducting quantum computing. Therefore, the world now generally believes that in the second stage of the competition, China will be in an advantageous position.
This breakthrough in the field of science and technology in China has more powerfully proved the importance of the principle of autonomy and controllability in China on the road of high-end technology research and development. As the Sino-US game and the pressure on China's science and technology continue to increase, we need to make key breakthroughs in major science and technology fields. Not long ago, the US intelligence services personally went down, listing a total of five major areas, reminding US companies not to cooperate with Chinese companies! In the South China Morning Post, the media disclosed an analysis published by the National Counterintelligence and Security Center. The report believes that in the future, artificial intelligence, biological sciences, semiconductors, quantum computing and autonomous operating systems will be "major areas that affect the world pattern", and the performance of American companies in these five major areas will "play a vital role in the long-term development of national security and economy in the United States". For the sake of U.S. national security, U.S. technology companies should vigorously avoid cooperating with Chinese companies or the government in these five areas.
Scientific and technological hegemony is an important reliance on the rampant western hegemonism, and at the moment when China's science and technology is constantly developing, the United States openly slanders China's scientific and technological undertakings, on the one hand, it exposes the ambition of the United States to continue hegemony in the field of science and technology, and on the other hand, it also shows that China's scientific and technological development cause has great potential and a bright future. The breakthrough in China's quantum technology is actually a powerful response to the hegemony of US science and technology!
In recent years, whether it is in the field of aerospace or quantum science and technology, Chinese scientific and technological personnel are using the sense of urgency that time is not waiting for me to overcome one scientific and technological "mountain" after another. In the face of the provocation of Western hegemonism, in the future we will use more "black technology" to give the provocateurs a strong counterattack! The trend of future scientific and technological development is becoming more and more clear, and Aerospace Jun believes that as long as we can seize the trend of a new round of scientific and technological revolution, we will certainly be able to break the hegemonist scientific and technological hegemony and disintegrate hegemony!
