Abstract: Landauer’s bound is applicable to irreversible quantum operations. In this study, we showcased that the Doppler temperature manifests the existence of Landauer’s bound, which does not block a spin from (irreversibly) flipping with a tiny… read more here.

Abstract: The thermodynamic cost of resetting an arbitrary initial state to a particular desired state is lower bounded by Landauer’s bound. However, here we demonstrate that this lower bound is necessarily unachievable for nearly every initial… read more here.

Abstract: The Landauer principle states that at least k_{B}Tln2 of energy is required to erase a 1-bit memory, with k_{B}T the thermal energy of the system. We study the effects of inertia on this bound using… read more here.

DOI: 10.3390/e24111568
Abstract: A generalized form of Landauer’s bound on the dissipative cost of classical information processing in quantum-mechanical systems is proved using a new approach. This approach sidesteps some prominent objections to standard proofs of Landauer’s bound—broadly… read more here.
