Abstract

In an isotopically pure 143Nd3+:Y7LiF4 crystal we demonstrate an optical quantum memory on a single photon level using the atomic frequency comb memory protocol. Using weakened laser pulses we demonstrate storage efficiency of 6.5% with the storage time of \( \sim \)60 ns and signal to noise ratio of around 3.

同位素纯 143Nd3+:Y7LiF4 晶体中的单光子级量子存储器
在同位素纯 143Nd3+:Y7LiF4 晶体中,我们利用原子频率梳记忆协议展示了单光子级光量子存储器。利用弱化的激光脉冲,我们展示了 6.5% 的存储效率,存储时间约为 60 毫微秒,信噪比约为 3。
