Landauer Principle Stands up to Quantum Test

Nonequilibrium quantum Landauer principle.

Using the operational framework of completely positive, trace preserving operations and thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system. Our bound comes from a nonphenomenological derivation of the Landauer principle which holds for generic nonequilibrium dynamics. Furthermore, the bound depends on the nonunita...

A note on the Landauer principle in quantum statistical mechanics

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 kBT log 2. We discuss Landauer’s principle for quantum statistical models describing a finite level quantum system S coupled to an infinitely extended thermal reservoirR. Using Araki’s perturbation theory of KMS states a...

Information transfer and Landauer s principle

In this paper we present an analysis of information transfer based on Landauer s principle (i.e., erasure of information is associated with an increase in entropy), as well as considerations of analyticity and causality. We demonstrate that holomorphic functions allowing complete analytic continuation cannot propagate any information, such that information transfer only occurs with analytic fun...

The Landauer resistivity on quantum wires

On Landauer principle and bound for infinite systems

Landauer principle provides a link between Shannon information entropy and Clausius thermodynamical entropy. We set up here a basic formula for the incremental free energy of a quantum channel, possibly relative to infinite systems, naturally arising by an Operator Algebraic point of view. By the Tomita-Takesaki modular theory, we can indeed describe a canonical evolution associated with a quan...
