论文摘要
我们探讨了开放量子系统中生成的熵的概念。从熵产生的角度来看，我们专注于对线路离散量子步行的研究。我们认为，硬币的演变可以建模为一个开放的两级系统，该系统在取决于初始状态的有效温度下将能量与晶格交换。熵平衡表明，根据热力学的第二定律，在进化过程中存在正熵产生。
We explore the notion of generated entropy in open quantum systems. We focus on the study of the discrete-time quantum walk on the line, from the entropy production perspective. We argue that the evolution of the coin can be modeled as an open two-level system that exchanges energy with the lattice at some effective temperature that depends on the initial state. The entropy balance shows that there is a positive entropy production during the evolution, in accordance with the second law of thermodynamics.
