金刚石中氮空位 (NV) 中心的大规模纠缠需要将 NV 中心与光网络集成。为了实现这一目标,我们提出了在金刚石上制造单晶磷化镓(GaP)谐振器波导耦合结构。我们演示了 1 μm 直径的 GaP 盘谐振器和负载 Q 因子为 3,800 的波导之间的耦合,并评估了它们与单光子发射器集成时有效收集光子的潜力。这项工作为混合 GaP/金刚石平台中的可扩展 NV 纠缠开辟了一条道路,并有可能集成片上光子收集、交换和检测,以用于量子信息处理中的应用。
Large-scale entanglement of nitrogen-vacancy (NV) centers in diamond will require integration of NV centers with optical networks. Toward this goal, we present the fabrication of single-crystalline gallium phosphide (GaP) resonator-waveguide coupled structures on diamond. We demonstrate coupling between 1 μm diameter GaP disk resonators and waveguides with a loaded Q factor of 3,800, and evaluate their potential for efficient photon collection if integrated with single photon emitters. This work opens a path toward scalable NV entanglement in the hybrid GaP/diamond platform, with the potential to integrate on-chip photon collection, switching, and detection for applications in quantum information processing.
