Scientists in China Achieve Quantum Key Distribution in Thousand Kilometers of Relay Free Fiber Optics
Hefei, May 29 (Reporter Xu Jing) -- Pan Jianwei and Zhang Qiang of the University of Science and Technology of China, together with Wang Xiangbin of Tsinghua University, Liu Yang of Jinan Institute of Quantum Technology, You Lixing and Zhang Weijun of the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences, have cooperated to achieve 1002km point-to-point long-distance quantum key distribution in optical fibers by developing technologies such as low crosstalk phase reference signal control and extremely low noise single photon detectors, Not only has it set a world record for fiber optic relay free quantum key distribution distance, but it also provides a solution for high-speed backbone links in intercity quantum communication. The relevant research results were recently published in the international academic journal "Physical Review Letters"...
