Wang Xiangbin, male, of Han nationality, was born in Wuwei County, Anhui Province in September 1967. He has a postgraduate degree and a doctorate degree. He first taught at the University of Science and Technology of China, and has been a professor in the Department of Physics of Tsinghua University since 2006. In 2007, he was funded by the National Science Fund for Distinguished Young Scholars of the National Natural Science Foundation of China. In 2009, he was hired as a distinguished professor of the Chang Jiang Scholars Program of the Ministry of Education. He is currently the Dean of Jinan Institute of Quantum Technology and Director of the Technical Committee of Shandong Institute of Quantum Science and Technology Co., Ltd. He is senior member of the Chinese Association for Cryptologic Research, member of the Quantum Cryptologic Professional Committee, and member of the Cryptologic Mathematics Professional Committee. He is mainly engaged in the theoretical research of quantum cryptography and quantum information science. In 2005, as the sole author, he published a three-strength decoy-state quantum key distribution scheme in PRL, which greatly increased the security distance of quantum cryptographic distribution based on weak coherence from the original 20 kilometers to 120 to 150 kilometers. The three-strength method and its variant methods have been widely experimentally confirmed and cited, and have been cited more than 500 times by others in SCI papers like Nature and its series, RMP, and PRL, and have been successfully applied to the Mozi scientific experimental satellite. In 2016, a four-strength optimization decoy-state MDI-QKD communication protocol was proposed. It was the first time in the world to achieve a quantum key distribution experiment that resisted quantum hacker attacks over 400 kilometers, which increased the bit rate to a practical level. This theory has also won experimental verification and application of other experimental teams.
