我们回顾了量子光学中的时间模式（TM）的概念，强调了罗伊·格劳伯对它们的发展所做的重要和历史性的贡献，以及它们在量子信息科学中日益增长的重要性。TM是可以用于表示多模光场的波包的正交集合。它们是光的横向空间模式的时间对应物，并发挥类似的作用-将多模光分解为最自然的基础，以隔离统计独立的自由度。我们讨论了如何开发TM来描述复杂的各种过程：超荧光，受激拉曼散射，自发参量下转换，自发四波混频。TM可以被操纵，转换，解复用，和检测使用非线性光学过程，如三波混频和量子光学存储器。因此，它们在构建量子信息网络中发挥着越来越重要的作用。
We review the concepts of temporal modes (TMs) in quantum optics, highlighting Roy Glauber’s crucial and historic contributions to their development, and their growing importance in quantum information science. TMs are orthogonal sets of wave packets that can be used to represent a multimode light field. They are temporal counterparts to transverse spatial modes of light and play analogous roles—decomposing multimode light into the most natural basis for isolating statistically independent degrees of freedom. We discuss how TMs were developed to describe compactly various processes: superfluorescence, stimulated Raman scattering, spontaneous parametric down conversion, and spontaneous four-wave mixing. TMs can be manipulated, converted, demultiplexed, and detected using nonlinear optical processes such as three-wave mixing and quantum optical memories. As such, they play an increasingly important role in constructing quantum information networks.
