Hong-Ou-Mandel（HOM）干扰是揭示单个光子非经典行为的最基本量子力学效应之一。两个相同的光子入射在公正的梁分离器的输入端口上，总是从同一输出端口一起退出光束分离器，这一效果称为光子束。在这封信中，我们利用单个电磁相调节器作为概率频梁分离器，我们利用它来观察到不同光谱模式的两个光子之间的HOM干扰，但在其他特征上是相同的。我们的方法可以使用线性光学器件等光子（例如量子计算技术）中的自由度频率来实现线性光学量子信息处理协议。 （c）2018美国光学学会
The Hong-Ou-Mandel (HOM) interference is one of the most fundamental quantum-mechanical effects that reveal a nonclassical behavior of single photons. Two identical photons that are incident on the input ports of an unbiased beam splitter always exit the beam splitter together from the same output port, an effect referred to as photon bunching. In this Letter, we utilize a single electro-optic phase modulator as a probabilistic frequency beam splitter, which we exploit to observe HOM interference between two photons that are in different spectral modes, yet are identical in other characteristics. Our approach enables linear optical quantum information processing protocols using the frequency degree of freedom in photons such as quantum computing techniques with linear optics.
