Landauer's principle in multipartite open quantum system dynamics

TL;DR

This paper explores how Landauer's principle relates heat dissipation and entropy change in multipartite quantum systems, highlighting the role of correlations and non-Markovian dynamics in open quantum system thermodynamics.

Contribution

It demonstrates that Landauer's principle applies to multipartite open quantum systems and links heat, entropy, correlations, and non-Markovian effects explicitly.

Findings

Landauer's principle holds in multipartite quantum systems with heat and entropy flow.

Correlation creation rate influences the thermodynamic behavior.

Non-Markovian dynamics are connected to entropy and heat exchange processes.

Abstract

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 {\it 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.
