We investigate the link between information and thermodynamics embodied by Landauer's principle in the open dynamics of a multipartite quantum system. Such irreversible dynamics is described in terms of a collisional model with a finite temperature reservoir. We demonstrate that Landauer's principle holds, for such a configuration, in a form that involves the flow of heat dissipated into the environment and the rate of change of the entropy of the system. Quite remarkably, such a principle for heat and entropy power can be explicitly linked to the rate of creation of correlations among the elements of the multipartite system and, in turn, the non-Markovian nature of their reduced evolution. Such features are illustrated in two exemplary cases.
我们研究了由 Landauer 原理所体现的信息与热力学之间的联系，该原理体现在多分量量子系统的开放动力学中。这种不可逆动力学可以用具有有限温度储层的碰撞模型来描述。我们证明了，对于这种配置，Landauer 原理以涉及耗散到环境中的热量流和系统熵变化率的形式成立。非常显著的是，这种热和熵功率的原理可以明确地与多分量系统各元素之间关联的产生速度联系起来，并且反过来，与它们的约化演化的非马尔可夫性质联系起来。这两个示例说明了这些特征。
