摘要

我们通过实验证明，在量子频率转换到电信波段时，NV自旋和光子之间的纠缠保持不变。这是实现远距离量子网络的关键一步。

Entanglement between Nitrogen-Vacancy spin in diamond and Telecom frequency photon

We experimentally demonstrate the preservation of entanglement between an NV spin and a photon upon quantum frequency conversion to the Telecom band. This is a crucial step in realizing long-distance quantum networks.
