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…
Time-Frequency Transfer through a 70 dB Free Space Channel: Towards Satellite-Ground Time Dissemination
Qi Shen, Jian-Yu Guan, Ting Zeng +15
Time and frequency transfer lies at the heart of the field of metrology. Compared to current microwave dissemination such as GPS, optical domain dissemination can provide more than…
Super-resolution single-photon imaging at 8.2 kilometers
Zheng-Ping Li, Xin Huang, Peng-Yu Jiang +6
Single-photon light detection and ranging (LiDAR), offering single-photon sensitivity and picosecond time resolution, has been widely adopted for active imaging applications. Long-…
