Validity of the Landauer's principle in the quantum regime — •Stefanie Hilt¹, Janet Anders², Eric Lutz¹, and Saroosh Shabbir² — ¹Department of Physics, University of Augsburg, 86135 Augsburg, Germany — ²Department of Physics, University College London, London, WC1E 6BT, UK

Landauer's principle gives a lower bound to the heat dissipated during the erasure of information. It is a key component of quantum information processing, since it provides a fundamental connection between information theory and thermodynamics. The validity of the erasure principle has been challenged constantly, especially in the quantum regime where entanglement plays an important role. We show that the Landauer bound holds even in the strong-coupling quantum regime.
