@article{Jaksic2014ANO, title={A note on the Landauer principle in quantum statistical mechanics}, author={Vojkan Jaksic and Claude-Alain Pillet}, journal={Journal of Mathematical Physics}, year={2014}, volume={55}, pages={075210} }

The Landauer principle asserts that the energy cost of erasure of one bit of information by the action of a thermal reservoir in equilibrium at temperature T is never less than kT log 2. We discuss Landauer's principle for quantum statistical models describing a finite level quantum system S coupled to an infinitely extended thermal reservoir R. Using Araki's perturbation theory of KMS states and the Avron-Elgart adiabatic theorem we prove, under a natural ergodicity assumption on the joint… Expand
