Spatial Multiplexing of Atom-Photon Entanglement Sources
Zhongxiao Xu, Long Tian, Shujing Li, Hai Wang · Conference on Lasers and Electro-Optics · 2018
We build a multiplexed light-matter interface and then demonstrate a ~sixfold (~fourfold) probability increase in generating entangled atom-photon (photon-photon) pairs. The measured compositive Bell parameter for the multiplexed interface is 2.49±0.03 combined with a memory lifetime of up to ~51 μs.
