论文摘要
基于钻石中的颜色中心和片上光子设备的颜色中心整合原子量子记忆将使纠缠分布在长距离内。但是，融合的努力是具有挑战性的，因为颜色中心可以对其环境高度敏感，并且其性质在纳米制造结构中降低。在这里，我们描述了一个异质整合的，片上的III-V钻石平台，设计用于钻石中的中性硅空位（SIV0）中心，该平台规避了蚀刻钻石底物的需求。通过evansent的耦合到钻石表面附近的SIV0中心，该平台将使Purcell增强SIV0发射和有效的频率转换为电信C波段。提出的结构可以通过随时可用的制造技术来实现。
Integrating atomic quantum memories based on color centers in diamond with on-chip photonic devices would enable entanglement distribution over long distances. However, efforts towards integration have been challenging because color centers can be highly sensitive to their environment, and their properties degrade in nanofabricated structures. Here, we describe a heterogeneously integrated, on-chip, III-V diamond platform designed for neutral silicon vacancy (SiV0) centers in diamond that circumvents the need for etching the diamond substrate. Through evanescent coupling to SiV0 centers near the surface of diamond, the platform will enable Purcell enhancement of SiV0 emission and efficient frequency conversion to the telecommunication C-band. The proposed structures can be realized with readily available fabrication techniques.
