Experimental Passive Decoy-State Quantum Key Distribution
Qi-Chao Sun, Wei-Long Wang, Yang Liu +8
The decoy-state method is widely used in practical quantum key distribution systems to replace ideal single photon sources with realistic light sources by varying intensities. Inst…
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…
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…
