摘要:

提出了一种利用金刚石中的氮空位(NV)中心实现微波与可见光光子相干量子界面的有效方案。在该设置中,NV中心系综同时耦合到光学腔和微波腔。我们发现,通过使用集体自旋激发模式作为中介,量子态可以通过双交换方案或暗态协议在微波腔和光学腔之间转移。这种混合量子界面在单微波光子探测或量子信息处理中可能提供有趣的应用。

英文摘要:

We propose an efficient scheme for a coherent quantum interface between microwave and optical photons using nitrogen-vacancy (NV) centers in diamond. In this setup, an NV center ensemble is simultaneously coupled to an optical and a microwave cavity. We show that, by using the collective spin excitation modes as an intermediary, quantum states can be transferred between the microwave cavity and the optical cavity through either a double-swap scheme or a dark-state protocol. This hybrid quantum interface may provide interesting applications in single microwave photon detections or quantum information processing.
