论文摘要
本文为量子辐射和局部量子系统的行进脉冲之间的相互作用提供了通用的主方程形式主义。行进场填充了自由空间辐射模式的连续体和Jaynes-Cummings模型，该模型对空腔的离散本特征有效。我们开发了一个完整的投入输出理论，以描述辐射的任意入射脉冲以及发出的量子状态驱动量子系统的驱动。我们的理论适用于辐射脉冲通过与宽类材料量子系统的耦合的转化和相互作用。我们讨论了与脉冲与离散的辐射本征的量子相互作用之间最重要的差异，并与具有光学，微波和声波的量子信息方案相关的示例进行了示例。
This article presents a general master equation formalism for the interaction between travelling pulses of quantum radiation and localized quantum systems. Traveling fields populate a continuum of free space radiation modes and the Jaynes-Cummings model, valid for a discrete eigenmode of a cavity, does not apply. We develop a complete input-output theory to describe the driving of quantum systems by arbitrary incident pulses of radiation and the quantum state of the field emitted into any desired outgoing temporal mode. Our theory is applicable to the transformation and interaction of pulses of radiation by their coupling to a wide class of material quantum systems. We discuss the most essential differences between quantum interactions with pulses and with discrete radiative eigenmodes and present examples relevant to quantum information protocols with optical, microwave and acoustic waves.
