Why does the Political Bureau of the CPC Central Committee study quantum technology collectively?

On August 16, 2016, Mozi quantum science experimental satellite was successfully launched. The mysterious concept of “quantum” raised the veil in front of the public. In recent years, quantum science and technology has developed by leaps and bounds, and has become the forefront of a new round of scientific and technological revolution and industrial transformation. Accelerating the development of quantum science and technology plays a very important role in promoting high-quality development and ensuring national security. Recently, the Political Bureau of the CPC Central Committee held the 24th collective study on the research and application prospects of quantum science and technology. Xue Qikun, vice president of Tsinghua University and academician of Chinese Academy of Sciences, explained the issue and put forward his opinions and suggestions. What are the contents of this special explanation? In the development of quantum technology, how to grasp the general trend and play a good first hand chess? Pan Yi and Li Xin, reporters from CCTV Central Committee, interviewed academician Xue Qikun. In recent years, quantum technology has developed by leaps and bounds, and has become the forefront of a new round of scientific and technological revolution and industrial transformation. Accelerating the development of quantum science and technology plays a very important role in promoting high-quality development and ensuring national security. At the collective learning with the theme of “research and application prospects of quantum science and technology”, General Secretary Xi said that the purpose of arranging the collective learning was to understand the development trend of quantum science and technology in the world, analyze the development situation of quantum science and technology in China, and better promote the development of quantum science and technology in China. Xue Qikun, vice president of Tsinghua University and academician of Chinese Academy of Sciences, explained the significance of quantum technology. < p > < p > Xue Qikun: in the future, quantum technology will not only improve the computing power of our computers, but also make the sensing technology more sensitive and the information accuracy more and more accurate. All these aspects will be greatly improved. It will play a truly revolutionary role in the future digital technology and quantum technology, and other technologies are gradual development. < p > < p > quantum mechanics is an important achievement of human exploring the micro world. The development of quantum science and technology is of great scientific significance and strategic value. It is a major disruptive technological innovation that impacts and reconstructs the traditional technology system, and will lead a new round of scientific and technological revolution and industrial transformation direction. Xue Qikun said that quantum technology is not far away from us. < p > < p > Xue Qikun: quantum technology is not a very new thing. Quantum mechanics has been established for more than 100 years. The understanding and development of quantum science have led to modern information technology, computer, communication, high-density information storage and global positioning system, all of which are implicit applications of quantum technology. Now we are talking about quantum computer and quantum communication, which is the second generation of quantum technology, which focuses more on actively designing a quantum system and developing quantum applications. The advent of the information age is actually closely related to quantum technology and the past. Now, quantum computing and quantum communication are more obvious and direct. Today’s world is experiencing unprecedented changes in a century, and technological innovation is one of the key variables. If we want to cultivate opportunities in the crisis and open up a new situation in the changing situation, we must ask for the answer from scientific and technological innovation. In recent years, Chinese scientists and technicians have caught up with each other in Quantum Science and technology, and have made a number of significant innovation achievements with international influence. < p > < p > Xue Qikun: there are many bright spots in basic research, and there are also many progresses in quantum precision measurement and sensing. For example, the time measurement system used by Beidou has been improved to a very high precision, which is an important application of quantum technology in global positioning or satellite navigation system. Recently, an experiment on a quantum satellite has achieved the quantum key distribution of 1000 kilometers, which is also the achievement just made this year. Whether in basic research, or in communication, quantum computing, including precision measurement and sensing, our country has a lot of things to be worth noting. On the whole, China has possessed the scientific and technological strength and innovation ability in the field of quantum science and technology. At the same time, we should also see that there are many shortcomings in the development of China’s Quantum Science and technology, and the development is facing multiple challenges. < p > < p > Xue Qikun: in fact, in terms of quantum technology and quantum technology, our short board is a little similar to that of information technology now. For example, support equipment, key core components and other aspects also involve some problems of quantum technology. Therefore, I think that strengthening key core components, which are high-end technical materials and equipment, are some short boards that need to be solved 。 The development of quantum science and technology depends on the breakthrough of basic theoretical research, and the formation of subversive technology is a process of accumulation. General Secretary Xi stressed in his speech when he presided over the study that it is necessary to speed up the breakthrough in basic research and the tackling of key core technologies, to bravely climb the scientific peak despite difficulties and obstacles, and to achieve a batch of high-level original achievements in the field of quantum science and technology. Xue Qikun was deeply touched by this. < p > < p > Xue Qikun: some quantum technologies can win economic and social development in a short time, but many of them belong to basic research, such as quantum computing. Now there are seven or eight technical solutions proposed internationally, which still need basic research and exploration. This is why we should strengthen international cooperation, strengthen talent training and reserve talent training And so on, because it involves a very basic level of scientific breakthrough, we can finally make the development of quantum computer to a feasible and engineering stage. However, unlike many basic research or scientific explorations that have no clear application goals, quantum technology, including quantum information technology, has a clearer application prospect. Xue Qikun said that it is very important to improve the speed and efficiency of the transformation of theoretical research results of quantum science and technology to practical and engineering applications. < p > < p > Xue Qikun: it should be said that it is quantum technology, including quantum information technology. We are still quite clear about its application prospects. Therefore, it can improve the efficiency and speed up the research and development by considering the cooperation between industry, University and Research Institute at the beginning of deployment and the close combination from basic research to application. In this collective study, General Secretary Xi made an important speech, pointing out that we must unswervingly follow the path of independent innovation, firm confidence, work hard, break through key core technologies, strive to achieve self-control in key areas, ensure the safety of the industrial chain supply chain, and enhance the ability of China’s Science and technology to cope with international risks and challenges. Xue Qikun: the speech of the general secretary has grasped the key problems as well as the systematic problems to be solved. As the scientific and educational workers fighting in the front line, we should implement the instructions of the Central Committee, and make contributions to the development of quantum science and technology in our country and human Quantum Science and technology. This is the duty and bounden duty of every Chinese scientist. Iqoo5 series debut strength interpretation of “120 super full mark flagship”
