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…
Polarization design for ground-to-satellite quantum entanglement distribution
Xuan Han, Hai-Lin Yong, Ping Xu +8
Polarization maintenance is a key technology for free-space quantum communication. In this paper, we describe a polarization maintenance design of a transmitting antenna with an av…
Point-ahead demonstration of a transmitting antenna for satellite quantum communication
Xuan Han, Hai-Lin Yong, Ping Xu +7
A low-divergence beam is an essential prerequisite for a high-efficiency longdistance optical link, particularly for satellite-based quantum communication. A point-ahead angle, cau…
Spaceborne low-noise single-photon detection for satellite-based quantum communications
Meng Yang, Feihu Xu, Ji-Gang Ren +9
Single-photon detectors (SPDs) play important roles in highly sensitive detection applications, such as fluorescence spectroscopy, remote sensing and ranging, deep space optical co…
Ground-to-satellite quantum teleportation
Ji-Gang Ren, Ping Xu, Hai-Lin Yong +29
An arbitrary unknown quantum state cannot be precisely measured or perfectly replicated. However, quantum teleportation allows faithful transfer of unknown quantum states from one…
Ground test of satellite constellation based quantum communication
Sheng-Kai Liao, Hai-Lin Yong, Chang Liu +22
Satellite based quantum communication has been proven as a feasible way to achieve global scale quantum communication network. Very recently, a low-Earth-orbit (LEO) satellite has…
Entanglement-based quantum key distribution with biased basis choice via free space
Yuan Cao, Hao Liang, Juan Yin +10
We report a free-space entanglement-based quantum key distribution experiment, implementing the biased basis protocol between two sites which are 15.3 km apart. Photon pairs from a…
Source attack of decoy-state quantum key distribution using phase information
Yan-Lin Tang, Hua-Lei Yin, Xiongfeng Ma +7
Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commerc…
Bounding the speed of `spooky action at a distance'
Juan Yin, Yuan Cao, Hai-Lin Yong +10
In the well-known EPR paper, Einstein et al. called the nonlocal correlation in quantum entanglement as `spooky action at a distance'. If the spooky action does exist, what is its…
Quantum teleportation and entanglement distribution over 100-kilometre free-space channels
Juan Yin, Ji-Gang Ren, He Lu +17
A long standing goal for quantum communication is to transfer a quantum state over arbitrary distances. Free-space quantum communication provides a promising solution towards this…
