Sheng-Kai Liao,Wen-Qi Cai,Wei-Yue Liu,Liang Zhang,Yang Li,Ji-Gang Ren,Juan Yin,Qi Shen,Yuan Cao,Zheng-Ping Li,Feng-Zhi Li,X. H. Chen,Lihua Sun,Jianjun Jia,Wu Jincai,Xiao-Jun Jiang,Jianfeng Wang,Yongmei Huang,Qiang Wang,Zhou Yilin,Deng Lei,Tao Xi,Lu Ma,Tai Hu,Qiang Zhang,Yu-Ao Chen,Nai-Le Liu,Xiang-Bin Wang,Zhen-Cai Zhu,Chao-Yang Lu,Rong Shu,Rong Shu,Cheng-Zhi Peng,Jianyu Wang,Jianyu Wang,Jian-Wei Pan +35 more
TL;DR: This work reports the development and launch of a low-Earth-orbit satellite for implementing decoy-state QKD—a form ofQKD that uses weak coherent pulses at high channel loss and is secure because photon-number-splitting eavesdropping can be detected.
Journal ArticleDOI
Single quantum emitters in monolayer semiconductors
Yu-Ming He,Genevieve Clark,John Schaibley,Yu He,Ming-Cheng Chen,Yu-Jia Wei,Xing Ding,Qiang Zhang,Wang Yao,Xiaodong Xu,Chao-Yang Lu,Jian-Wei Pan +11 more
TL;DR: A new class of SQEs based on excitons that are spatially localized by defects in 2D tungsten-diselenide (WSe2) monolayers is reported, which could give rise to practical advantages in quantum-information processing, such as an efficient photon extraction and a high integratability and scalability.
Journal ArticleDOI
Quantum key distribution over a 40-dB channel loss using superconducting single-photon detectors
Hiroki Takesue,Sae Woo Nam,Qiang Zhang,Robert H. Hadfield,Robert H. Hadfield,Toshimori Honjo,Kiyoshi Tamaki,Yoshihisa Yamamoto,Yoshihisa Yamamoto +8 more
TL;DR: The keys generated in the first quantum key distribution experiment to enable the creation of secure keys over 42 dB channel loss and 200 km of optical fibre are secure against both general collective attacks on individual photons and a specific collective attack on multiphotons.
Journal ArticleDOI
Secure quantum key distribution with realistic devices
TL;DR: This review gives both sides of the story, with the current best theory of quantum security, and an extensive survey of what makes quantum cryptosystem safe in practice.
Journal ArticleDOI
Measurement-Device-Independent Quantum Key Distribution Over a 404 km Optical Fiber.

TL;DR: This record-breaking implementation of the MDIQKD method provides a new distance record and achieves a distance that the traditional Bennett-Brassard 1984 QKD would not be able to achieve with the same detection devices even with ideal single-photon sources.
