摘要:

我们报告了在适合长距离低损耗通信的波长下观察到单个被困原子和单个光子之间的纠缠,从而实现了向远程量子网络迈出的关键一步。为了验证纠缠,我们引入了一个单原子态分析。该技术用于原子-光子量子比特对的全态层析成像。探测效率和纠缠保真度足够高,可以在下一步中产生大距离的纠缠原子,为最终的无空洞贝尔实验做好准备。

英文摘要:

We report the observation of entanglement between a single trapped atom and a single photon at a wavelength suitable for low-loss communication over large distances, thereby achieving a crucial step towards long range quantum networks. To verify the entanglement we introduce a single atom state analysis. This technique is used for full state tomography of the atom-photon qubit-pair. The detection efficiency and the entanglement fidelity are high enough to allow in a next step the generation of entangled atoms at large distances, ready for a final loophole-free Bell experiment.
