Entangled photon pairs are a critical resource in quantum communication protocols ranging from quantum key distribution to teleportation. The current workhorse technique for producing photon pairs is via spontaneous parametric down conversion (SPDC) in bulk nonlinear crystals. The increased prominence of quantum networks has led to a growing interest in deployable high performance entangled photon-pair sources. This manuscript provides a review of the state-of-the-art bulk-optics-based SPDC sources with continuous wave pump and discusses some of the main considerations when building for deployment.

基于体波三波混合的纠缠光子对源

纠缠的光子对是量子通信协议中从量子密钥分发到远距传输的关键资源。当前用于产生光子对的主力技术是通过块状非线性晶体中的自发参数下转换(SPDC)。量子网络的日益突出引起人们对可部署的高性能纠缠光子对源的兴趣日益增长。该手稿对具有连续波泵的最新的基于体光学的SPDC源进行了回顾,并讨论了在进行部署时需要考虑的一些主要因素。
