Einstein , Bordosky and Rosen proposed a paradox in 1935. If a physical theory describes physical reality in a complete way, then every element of physical reality must have its corresponding quantity, that is, the criterion of completeness. When we can predict the value of a physical quantity without interfering with the system, there must be a physical reality element corresponding to this physical quantity, that is, the criterion of reality. They believe that quantum mechanics does not meet these criteria, so it is incomplete.
This paradox takes one letter from three great physicists, called the EPR paradox, also called the EPR paradox.
Later, this thought experiment that originally wanted to falsify quantum mechanics was actually proved.
022 Nobel Prize in Physics was jointly awarded to French physicist Alain Aspect, American physicist John F. Clauser and Austrian physicist Anton Zeilinger for "entangled photon experiments, establishing violations of Bell inequality and groundbreaking quantum information science ".
, especially Salinger, has a lot of connections with China.
. Salinger is a doctoral supervisor of Pan Jianwei . He himself is a foreign academician of Chinese Academy of Sciences and an honorary professor at N universities in China. It is a quantum entanglement application that many people define as a fraud in funds, but even Nobel Prize was cheated.
. Salinger won the Nobel Prize , which means that Pan Jianwei will also lose the qualification to win the Nobel Prize in the future. After all, the same field will generally not be awarded twice.
. When announcing the Nobel Prize in Physics, Pan Jianwei's team's Mozihao appeared as a case, which is one of the basis for confirming quantum entanglement.
4. Salinger is a fan of Adams' " Galaxy Hitchhiker Guide ". His sailing boat was named "42".
After the mentor won the Nobel Prize in Physics, Pan Jianwei was very excited to accept the interview.
"The awards committee mentioned four quantum communication experimental articles by my mentor Anton Salinger . I am the first author of two of them and the second author of the two." Pan Jianwei said.
At the same time, "The Awards Committee also mentioned three other articles, and these three articles are independent research work carried out by Chinese scientists. So, from this point of view, I not only joined Salinger's research team, but also participated in the creation of the field of quantum information physics. I feel very lucky." Pan Jianwei said.
More importantly, "Chinese scientists have also made great contributions in the process of turning the dream of award-winning scientists into reality." Pan Jianwei felt very proud of his achievements in this regard. The deputy chief of Mo Zihao who works with Pan Jianwei is Peng Chengzhi, a professor and doctoral supervisor at the University of Science and Technology of China. He is also the chairman of a listed company in the Science and Technology Innovation Board. He has won the first prize of the National Natural Science Award, the first prize of the military science and technology progress and other awards. The research results have been published many times in the form of covers (titles) in the form of top international academic journals "Nature" and "Science".
This company is called Guodun Quantum. This small company has also been listed on the entity list in the United States and has been listed twice (authoritative technical certification).
The largest shareholder of Guodun Quantum is the University of Science and Technology of China, and the second largest shareholder is Pan Jianwei, a famous quantum mechanics expert and academician of the Chinese Academy of Sciences.
An interesting gossip: Austrian Salinger is a foreign academician of the Chinese Academy of Sciences, and Chinese Pan Jianwei is a foreign academician of the Austrian Academy of Sciences.
Company's technology originated from University of Science and Technology of China and has gradually grown into one of the few companies in the world with full capabilities in design, supply and deployment of large-scale quantum confidential communication networks.The company provides software and hardware products for various fiber quantum confidential communication networks and "Star-earth-integrated" wide-area quantum confidential communication networks, promoting the seamless connection between quantum confidential communication networks and classic communication networks, and providing quantum security application solutions to customers in various industries and fields such as government affairs, finance, and electricity.
core equipment of quantum confidential communication network (QKD products, miniaturized ground receiving stations of quantum satellites, channel and key network switching products, etc.), quantum security application products (fixed network encryption application products, mobile encryption application products, etc.), core components ( single photon detector , quantum random number source, etc.), and management and control software of quantum confidential communication networks.
In 2021, Guodun Quantum had revenue of 179 million yuan. Due to the relatively high R&D investment, the company has not yet made a profit and its net profit loss is 37 million yuan.
According to the company's 2022 semi-annual report, in addition to the fields related to quantum communications, the company has also participated in the research and development of the superconducting quantum computing prototype " Zuchong Zhihao ", which has achieved the milestone of "quantum computing superiority". The company continues to upgrade the superconducting quantum computing control system and improves the equipment's performance, versatility, stability, modularity, etc.; the company has the ability to build customized superconducting quantum computing prototypes.
In 2021, Pan Jianwei's team successfully developed the 62-bit programmable superconducting quantum computing prototype "Zu Chongzhi" and realized programmable two-dimensional quantum walking on this basis. The strongest supercomputer requires at least 8 years of sampling task and it can be completed in 1.2 hours.
On May 7, 2021, this research result was published in the international academic journal Science. In October of the same year, based on the "Zu Chong Zhizhi", the optimized "Zu Chong Zhizhi 2" was released, which made a greater improvement. High-density integration of 66 data bits, 110 coupled bits, and 11 reads, the maximum state space dimension reaches 1019. The computational complexity is one million times higher than the "Sycamore" prototype of the same type of superconducting quantum computing machine of Google .
According to the company's semi-annual report, there are currently 24 projects under development.
