Microsatellite-based real-time quantum key distribution
Yang Li, Wen-Qi Cai, Ji-Gang Ren +38
A quantum network provides an infrastructure connecting quantum devices with revolutionary computing, sensing, and communication capabilities. As the best-known application of a qu…
Portable ground stations for space-to-ground quantum key distribution
Ji-Gang Ren, Maimaiti Abulizi, Hai-Lin Yong +23
Quantum key distribution (QKD) uses the fundamental principles of quantum mechanics to share unconditionally secure keys between distant users. Previous works based on the quantum…
Implementation of a 46-node quantum metropolitan area network
Teng-Yun Chen, Xiao Jiang, Shi-Biao Tang +22
Quantum key distribution (QKD) enables secure key exchanges between two remote users. The ultimate goal of secure communication is to establish a global quantum network. The existi…
Single-mode fiber coupling with a M-SPGD algorithm for long-range quantum communications
Kui-Xing Yang, Maimaiti Abulizi, Yu-Huai Li +7
Satellite-based quantum communication is a promising approach for realizing global-scale quantum networks. For free-space quantum channel, single-mode fiber coupling is particularl…
Long-distance free-space measurement-device-independent quantum key distribution
Yuan Cao, Yu-Huai Li, Kui-Xing Yang +20
Measurement-device-independent quantum key distribution (MDI-QKD), based on two-photon interference, is immune to all attacks against the detection system and allows a QKD network…
Towards satellite-based quantum-secure time transfer
Hui Dai, Qi Shen, Chao-Ze Wang +11
High-precision time synchronization for remote clocks plays an important role in fundamental science and real-life applications. However, the current time synchronization technique…
