论文摘要
控制量子光脉冲的时间模式形状具有广泛的范围应用于量子信息科学和技术。已经开发了控制带宽，允许在时间和频域中移动并执行模式选择光束示单式转换的技术。但是，目前尚无在时间模式上执行目标多模统一转换的方案。在这里，我们提出了一种实践方法，以实现时间模式的一般转变。从理论上讲，我们可以在时间和频域中使用一系列相位操作执行时间模式上的任何统一转换。数值模拟表明，使用实验可行的规格可以以超过95％的保真度进行时间模式上的几个关键转换。
Controlling the temporal mode shape of quantum light pulses has wide ranging application to quantum information science and technology. Techniques have been developed to control the bandwidth, allow shifting in the time and frequency domains, and perform mode-selective beam-splitter-like transformations. However, there is no present scheme to perform targeted multimode unitary transformations on temporal modes. Here we present a practical approach to realize general transformations for temporal modes. We show theoretically that any unitary transformation on temporal modes can be performed using a series of phase operations in the time and frequency domains. Numerical simulations show that several key transformations on temporal modes can be performed with greater than 95% fidelity using experimentally feasible specifications.
