Behind the publication of “nine chapters”: the first authors of team papers are all post-90s!

On December 4, the University of science and technology of China announced that Pan Jianwei and others had successfully built a 76 photon quantum computing prototype “nine chapters”, which only took 200 seconds to solve the mathematical algorithm of Gaussian boson sampling, while the world’s fastest supercomputer took 600 million years, Xinhua reported. This breakthrough makes China the second country in the world to realize “quantum superiority”. On December 4, the international academic journal published the achievement, and the reviewers evaluated it as “a most advanced experiment” and “a major achievement”. According to the reporter, there are also a group of post-90s in the research and development team of “nine chapters”, among which four first authors were born in 1995, 1991, 1997 and 1990. Deng Yuhao, the youngest, was born in 1997. He studied under Professor Lu Chaoyang and pan Jianwei. He graduated from junior class College of China University of science and technology. < p > < p > ZHONG Hansen, born in 1995, studied under Professor Lu Chaoyang and pan Jianwei, and joined the team in 2016. At the same time, it is devoted to the demonstration of the entangled photon source. The theory and experimental scheme of Gaussian boson sampling are developed, and the feasibility of 5-photon Gaussian boson sampling is demonstrated for the first time. Recently, 76 photon Gaussian Bose sampling quantum computation with 50 single-mode squeezed state input and 100 mode output has been realized, which is 10 ^ 14 times faster than that of supercomputer, which proves the superiority of quantum computing. Wang Hui, born in 1991 and under the guidance of Professor Lu Chaoyang and pan Jianwei, joined the team in 2015 and obtained his doctorate in 2020. For a long time, he has devoted himself to quantum dot single photon source and quantum computation, especially Bose sampling quantum computation. In the aspect of single photon source, the problem of 50% loss caused by orthogonal extinction is solved by elliptical cavity and two-color excitation. The paper is selected as the cover of nature photonis; the intensity compression phenomenon is observed for the first time in the solid-state quantum dot system; the high-purity, high-efficiency, high fidelity and high-resolution deterministic entanglement light source are combined for the first time. < / P > < p > in the field of quantum computing, in 2017, it will achieve the goal of surpassing the early classic computers in the world, and the top 10 scientific and technological progress in China selected by academicians of the Chinese Academy of Sciences and Chinese Academy of Sciences. In 2019, Bose sampling with 20 photon input and 60 mode output will be realized based on single photon source of quantum dots, which approaches the important scientific goal of quantum computing superiority. Recently, 76 photon Gaussian Bose sampling quantum computation with 50 single-mode squeezed state input and 100 mode output has been realized, which is 10 ^ 14 times faster than that of supercomputer, which proves the superiority of quantum computing. Deng Yuhao, born in 1997, studied under Professor Lu Chaoyang and pan Jianwei, graduated from junior class College of University of science and technology of China, and went to ucla-csst summer research of University of California, Los Angeles and won the best research award. In 2017, he joined the team and realized quantum interference at astronomical scale for the first time. The experiment observed two-photon interference, quantum entanglement and nonlocality between single photon and sunlight of quantum dot. The experiment expanded the quantum interference experiment between independent photons to two independent light sources with a distance of 150 million km. The universality of quantum statistics principle was tested at the astronomical scale for the first time, and the thermal light was given Direct experimental evidence of field quantization. < / P > < p > as a representative of Chinese college students, he was selected to participate in the 70th Lindau Nobel Prize winners’ conference. We are committed to the development of optical quantum computation and quantum physics research based on quantum dot quantum light source and parametric quantum light source. Recently, 76 photon Gaussian Bose sampling quantum computation with 50 single-mode squeezed state input and 100 mode output has been realized, which is 10 ^ 14 times faster than that of supercomputer, which proves the superiority of quantum computing. < p > < p > Chen Mingcheng, born in 1990 and under the guidance of Professor Lu Chaoyang and pan Jianwei, joined the team in 2012 and obtained his doctor’s degree in 2017. He is now a special associate researcher of CUHK. He has been committed to theoretical and Experimental Research on quantum physics and scalable quantum computing for a long time, especially as team leader in theoretical exploration, design and algorithm analysis. Recently, a large-scale random quantum circuit in classical simulation inspired by quantum teleportation was proposed, which was cited as one of the most advanced algorithms by Google quantum hegemony experimental paper. The high-quality single photon source was jointly developed and 20 Recently, the 76 photon Gaussian Bose sampling quantum computation with 50 single-mode squeezed state input and 100 mode output has been realized, which is 10 ^ 14 times faster than that of supercomputer, which proves the superiority of quantum computing.
