Recent developments in chip-based photonic quantum circuits has radically impacted quantum information processing. However, it is challenging for monolithic photonic platforms to meet the stringent demands of most quantum applications. Hybrid platforms combining different photonic technologies in a single functional unit have great potential to overcome the limitations of monolithic photonic circuits. Our review summarizes the progress of hybrid quantum photonics integration, discusses important design considerations including optical connectivity and operation conditions, then highlights several successful realizations of key physical resources for building a quantum-teleporter. We conclude by discussing the roadmap for realizing future advanced large-scale hybrid devices, beyond the solid state platform, which hold great potential for quantum information applications.
基于芯片的光子量子电路的最新进展已从根本上影响了量子信息处理。然而，单片光子平台要满足大多数量子应用的严格要求具有挑战性。在单个功能单元中结合不同光子技术的混合平台具有巨大潜力，可克服单片光子电路的局限性。我们的综述总结了混合量子光子集成的进展，讨论了包括光学连接性和操作条件在内的重要设计考量，然后重点介绍了构建量子隐形传态器关键物理资源的几个成功实现案例。我们通过讨论实现未来先进大规模混合设备的路线图来得出结论，这些设备超越了固态平台，在量子信息应用方面具有巨大潜力。
