Conventional wisdom holds that the von Neumann entropy corresponds to thermodynamic entropy, but Hemmo and Shenker (2006) have recently argued against this view by attacking von Neumann's (1955) argument. I argue that Hemmo and Shenker's arguments fail due to several misunderstandings: about statistical mechanical and thermodynamic domains of applicability, about the nature of mixed states, and about the role of approximations in physics. As a result, their arguments fail in all cases: in the single-particle case, the finite particles case, and the infinite particles case.

冯诺依曼熵对应于热力学熵吗？

传统观点认为冯诺依曼熵对应于热力学熵，但 Hemmo 和 Shenker (2006) 最近通过攻击冯诺依曼 (1955) 的论点来反对这一观点。我认为 Hemmo 和 Shenker 的论点因以下几个误解而失败：关于适用性的统计力学和热力学领域，关于混合态的性质，以及关于近似值在物理学中的作用。结果，他们的论点在所有情况下都失败了：在单粒子情况下、有限粒子情况下和无限粒子情况下。
