Hong-Ou-Mandel (HOM) interference is one of the most important experimental phenomena in quantum optics. It has drawn considerable attention with respect to quantum cryptography and quantum communication because of the advent of the measurement device independent (MDI) quantum key distribution (QKD) protocol. Here, we realize HOM interference, having a visibility of approximately 38.1%, using two independent heralded single-photon sources (HSPSs). The HOM interference between two independent HSPSs is a core technology for realizing the long-distance MDI QKD protocol, the quantum coin-tossing protocol, and other quantum cryptography protocols.
Hong-Ou-Mandel（HOM）干涉是量子光学中最重要的实验现象之一。由于测量设备无关（MDI）量子密钥分发（QKD）协议的出现，它在量子密码学和量子通信方面引起了相当大的关注。在此，我们使用两个独立的 heralded 单光子源（HSPS）实现了可见度约为 38.1%的 HOM 干涉。两个独立 HSPS 之间的 HOM 干涉是实现长距离 MDI QKD 协议、量子抛硬币协议和其他量子密码学协议的核心技术。
