Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states, and, in the absence of local equilibrium, thermodynamics cannot be formulated correctly. Von Neumann entropy is not a thermodynamic quantity, although it can characterize the ordering of a system. In the case of the entanglement of the particles of the system with the environment, the concept of an isolated system should be refined. In any case, quantum correlations cannot lead to a violation of the second law of thermodynamics in any of its formulations. This article is devoted to a technical discussion of the expected results on the role of quantum entanglement in thermodynamics.

量子相关性会导致违反热力学第二定律吗？

量子纠缠会导致热机的效率大于卡诺循环的效率。但是，这并不意味着违反热力学第二定律，因为对于纯量子态没有局部平衡，并且在没有局部平衡的情况下，不能正确地制定热力学。冯·诺依曼熵不是一个热力学量，尽管它可以表征系统的有序性。在系统的粒子与环境纠缠的情况下，应完善隔离系统的概念。无论如何，量子相关性在任何形式下都不会导致违反热力学第二定律。本文致力于有关量子纠缠在热力学中作用的预期结果的技术讨论。
