Is quantum communication a pseudoscience?

The “Mozi No.” was launched almost three years ago. What new discoveries have it made? What is the connection between quantum communication and the public, is it pseudoscience? On the 10th, at the press conference held at the second session of the 13th National Committee of the Chinese People’s Political Consultative Conference, Pan Jianwei, member of the National Committee of the Chinese People’s Political Consultative Conference, executive vice president of the University of Science and Technology of China, and academician of the Chinese Academy of Sciences, had a lot to say.

What new discoveries have been made since the launch of the “Mozi” quantum science experimental satellite? Pan Jianwei said that the “Mozi No.” as a scientific experimental satellite has two main purposes, one of which is practical. In order to achieve quantum secure communication between ultra-long-distance satellites, there is also a basic scientific research goal. The “non-locality of quantum mechanics” proposed by Einstein is verified in the strict sense.

Pan Jianwei revealed that after the “Mozi No.” was issued, the performance index far exceeded expectations. The scientific test task originally planned to be completed within two years was completed within two or three months, so there was a lot of time to improve the performance. There is a big progress. At the same time, the “Mozi No.” has increased the amount of keys between the stars and the land by 40 times. Now, in one second, it is possible to transmit 400,000 keys, which can meet some preliminary security communication needs.

Pan Jianwei said that the “Mozi” also made a more interesting experiment. Because quantum mechanics and general relativity are not well combined, the proposed coordination model is proposed. The experiment of “Mozi No.” shows that some theoretical schemes are not correct in themselves, which is a relatively large progress.

Pan Jianwei said that he hopes to push quantum communication into practical use as soon as possible. In the future, he can develop a medium-high-orbit satellite, so that it can work 24 hours a day, to make up for the regret that the “Mozi” can only work at night, and ensure that it is even more Generate a key for a long time.

Over the years, the questioning of quantum communication has almost never been interrupted. Some people even think that quantum communication is a “pseudoscience.” In response, Pan Jianwei responded. He said that the public has doubts about quantum communication technology, mainly because quantum mechanics is very different from their life experience. Even those who are highly educated may not have advanced theory of quantum communication. Can be well understood. Therefore, the public will doubt the scientific nature of quantum communication and worry that this technology is not mature.

Pan Jianwei further explained that from the generation to the widespread application of innovation results, usually through three stages. In the first phase, the public is exposed to a new field of things, the initial response is usually: not reliable. For example, the earliest camera, everyone feels that the soul has been sucked into the camera, and they are not afraid to use it. Therefore, early quantum communication was considered to be pseudoscience. When it developed more maturely, it felt that this technology has not been widely applied and has doubts. “Now we do have a lot of innovative results that are already at the forefront of the world, and we should be confident.”

However, Pan Jianwei also said that at present, quantum communication is in the process of the second to third phase of conversion, and a lot of science work needs to be done. “After the application of the equivalent sub-communication, everyone felt that nothing was unusual, and the innovation process was completed.”

As for the role of quantum communication, Pan Jianwei said that information security is very important to the country and to the individual. From the password protection of bank accounts to the remote control of unmanned driving, quantum communication can provide an unconditional and secure communication in principle. Means will greatly improve the level of information security in the future.

Pan Jianwei said that China has a certain international competitiveness in the field of quantum information, and even in the international leading position in some directions, but it can not be too optimistic, and some advantages are strongly affected by developed countries in Europe and America. Compared with the traditional international science and technology powers, China’s previous research organization model is mainly based on short-term research projects, so it is still insufficient to meet the urgent needs of the national strategy, as well as the intensity of integration and support of scientific and technological resources. The enthusiasm for investment in science and technology has a certain gap compared with developed countries. “To make technological innovation in China, China needs the vision of the party and the country to carry out a holistic layout.

Pan Jianwei said that the quantum information science he has engaged in has entered a stage of deepening and rapid development. In particular, he needs multidisciplinary cross-integration and key technologies to tackle the problem. He hopes that the country will deploy major scientific and technological projects in this field and build a national experiment. room.

Last year, at a bi-weekly consultation meeting of the CPPCC National Committee, Pan Jianwei made a speech on “Strengthening the construction of national laboratories and building a high-level innovation team.” Considering that the current national strategies of the developed countries such as the European Union, the United States, and the United Kingdom in the field of quantum information technology have been launched, and international competition is fierce, Pan Jianwei suggested that China should substantially launch the national laboratory construction and scientific and technological innovation projects in related fields as soon as possible. At the same time, relying on the most advantageous innovation units in related fields, the construction and operation management of national laboratories will be carried out, and the overall deployment and implementation of relevant major scientific research tasks will be specifically undertaken.
