许多光量子信息处理协议的成功依赖于具有良好定义的空间和时间模式的光子态的可用性，但后者通常难以设计。本文提出了一种基于非线性干涉测量的新方法，将非线性增益控制与色散工程分离开来，使光子对同时具有高纯度、高采集效率、高亮度以及波长和带宽选择灵活等优点。
The success of many protocols in optical quantum information processing relies on the availability of photon states with a well-defined spatial and temporal mode, but the latter is often difficult to engineer. The authors present a new approach based on nonlinear interferometry that separates the nonlinear gain control from the dispersion engineering, resulting in photon pairs simultaneously possessing the advantages of high purity, high collection efficiency, high brightness, and flexibility in wavelength and bandwidth selection.
