We establish a fluctuation theorem for an open quantum bipartite system that explicitly manifests the role played by quantum correlation. Generally quantum correlations may substantially modify the universality of classical thermodynamic relations in composite systems. Our fluctuation theorem finds a non-equilibrium parameter of genuinely quantum nature that sheds light on the emerging quantum information thermodynamics. Specifically we show that the statistics of quantum correlation fluctuation obtained in a time-reversed process can provide a useful insight into addressing work and heat in the resulting thermodynamic evolution. We illustrate these quantum thermodynamic relations by two examples of quantum correlated systems.
我们为一个开放量子二分系统建立了一个涨落定理,该定理明确体现了量子关联所起的作用。一般来说,量子关联可能会显著改变复合系统中经典热力学关系的普遍性。我们的涨落定理找到了一个具有真正量子性质的非平衡参数,这为新兴的量子信息热力学提供了启示。具体而言,我们表明在时间反演过程中获得的量子关联涨落统计可以为理解由此产生的热力学演化中的功和热提供有用的见解。我们通过两个量子关联系统的例子来说明这些量子热力学关系。
