Effect of light injection on the security of practical quantum key distribution
Liying Han, Yang Li, Hao Tan +7
Quantum key distribution (QKD) based on the fundamental laws of quantum physics can allow the distribution of secure keys between distant users. However, the imperfections in reali…
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…
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…
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…
Satellite-relayed intercontinental quantum network
Sheng-Kai Liao, Wen-Qi Cai, Johannes Handsteiner +33
We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, and Graz, which establish satellite-t…
Satellite-Based Entanglement Distribution Over 1200 kilometers
Juan Yin, Yuan Cao, Yu-Huai Li +31
Long-distance entanglement distribution is essential both for foundational tests of quantum physics and scalable quantum networks. Owing to channel loss, however, the previously ac…
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…
Satellite-to-ground quantum key distribution
Sheng-Kai Liao, Wen-Qi Cai, Wei-Yue Liu +31
Quantum key distribution (QKD) uses individual light quanta in quantum superposition states to guarantee unconditional communication security between distant parties. In practice,…
A Compact PCI-based Measurement and Control System for Satellite-Ground Quantum Communication
Binxiang Qi, Shubin Liu, Qi Shen +6
Since the 1990s, there has been a dramatic interest in quantum communication. Free-space quantum communication is being developed to ultra-long distance quantum experiment, which r…
200km Decoy-state quantum key distribution with photon polarization
Teng-Yun Chen, Jian Wang, Yang Liu +10
We demonstrate the decoy-state quantum key distribution over 200 km with photon polarization through optical fiber, by using super-conducting single photon detector with a repetiti…
Field test of a practical secure communication network with decoy-state quantum cryptography
Teng-Yun Chen, Hao Liang, Yang Liu +9
We present a secure network communication system that operated with decoy-state quantum cryptography in a real-world application scenario. The full key exchange and application pro…
