Entropy production is the crucial quantity characterizing irreversible phenomena and the second law of thermodynamics. Yet, a ubiquitous definition eludes consensus. Given that entropy production arises from incomplete access to information, in this work we use Jaynes' maximum entropy principle to establish a framework that brings together prominent and apparently conflicting definitions. More generally, our definition of entropy production addresses any tomographically incomplete quantum measurement and/or the action of a quantum channel on a system.
熵产生是表征不可逆现象和热力学第二定律的关键量。然而，一个普遍适用的定义尚未达成共识。鉴于熵产生源于对信息的不完全获取，在这项工作中，我们使用杰恩斯的最大熵原理建立了一个框架，该框架汇集了突出且明显相互冲突的定义。更一般地说，我们对熵产生的定义适用于任何断层扫描不完全的量子测量和/或量子信道对系统的作用。
