摘要翻译:
在本文中,我们将讨论如何紧凑地表达和证明具有耗散动力学的开放量子系统的Jarzynski恒等式。我们将避免直接显式测量功,这无异于持续监控系统,而是测量来自环境的热流。我们用作用于系统密度矩阵的厄米图超算符来表示热流的测量。Hermitian映射提供了序列测量和相关函数的方便和紧凑的表示。

英文摘要:
In this note, we will discuss how to compactly express and prove the Jarzynski identity for an open quantum system with dissipative dynamics. We will avoid explicitly measuring the work directly, which is tantamount to continuously monitoring the system, and instead measure the heat flow from the environment. We represent the measurement of heat flow with Hermitian map superoperators that act on the system density matrix. Hermitian maps provide a convenient and compact representation of sequential measurement and correlation functions.
