频率自由度与发达的无所不在的光通信基础设施兼容，允许量子信息的稳定，可控和可扩展的编码[1]。独立光子之间的HOM效应，作为中心构建块，例如，量子密钥分发（QKD）、量子隐形传态和纠缠交换主要应用于空间域[2]。实现量子计算和非经典通信的可扩展和基于真实世界频率的实现的一个关键要素是演示独立创建的不同频率光子之间的Hong-Ou-Mandel（HOM）干涉。迄今为止，已经证明了由相同的连续波（cw）激发的自发参量下转换（SPDC）过程产生的单光子之间的光谱玻色子HOM干涉[3]，然而，由于所提出的方法固有的光谱杂质，这不允许可扩展性。
The frequency degree-of-freedom, being compatible with well-developed omnipresent optical telecommunication infrastructure, allows for stable, controllable and scalable encoding of quantum information [1] . The HOM effect between independent photons, as a central building block to, e.g., quantum key distribution (QKD), quantum teleportation and entanglement swapping, has been mainly employed within the spatial domain [2] . A key element yet missing to enable scalable and thus real-world frequency-based implementation of quantum computation and non-classical communication, is the demonstration of Hong-Ou-Mandel (HOM) interference between independently created photons of different frequencies. To date, spectral bosonic HOM interference between single photons, produced out of the same continuous-wave (cw)-excited spontaneous parametric down conversion (SPDC) process has been demonstrated [3] , which however does not allow scalability due to the spectral impurity inherent to the proposed approach.
