论文摘要
这些笔记提供了有关“观察性熵”（也称为“量子粗粒熵”）的基本方面的简短入门，这是将粗粒剂概念应用于量子系统的一般框架。我们回顾了基本的形式主义，对热力学的调查应用，与量子相关性和纠缠熵建立联系，与相应的经典理论进行比较，并根据POVM测量讨论概括。
These notes provide a brief primer on the basic aspects of "observational entropy" (also known as "quantum coarse-grained entropy"), a general framework for applying the concept of coarse-graining to quantum systems. We review the basic formalism, survey applications to thermodynamics, make a connection to quantum correlations and entanglement entropy, compare to the corresponding classical theory, and discuss a generalization based on POVM measurements.
