Bell Test Over Extremely High-Loss Channels: Towards Distributing Entangled Photon Pairs Between Earth and Moon
Yuan Cao, Yu-Huai Li, Wen-Jie Zou +8
Quantum entanglement was termed "spooky action at a distance" in the well-known paper by Einstein, Podolsky, and Rosen. Entanglement is expected to be distributed over longer and l…
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,…
