On the Quantum Correction for Thermodynamic Equilibrium

Charlie Harper

A simplified derivation of Wigner's quantum-mechanical correction for thermodynamic equilibrium is presented. The analysis is restricted to the quantum statistics of systems with classical analogs.

Abstract We present our numerical study on quantum thermodynamics of the resonant level model subjected to non-equilibrium condition as well as external driving. Following our previous work on non-equilibrium quantum thermodynamics (Dou et al 2020 Phys. Rev. B 101 184304), we expand the density operator into a series of power in the driving speed, where we can determine the non-adiabatic thermodynamic quantities. Particularly, we calculate the non-equilibrium entropy production rate as well as higher order non-adiabatic corrections to the energy and/or population, which is not determined previously in Dou et al (2020 Phys. Rev. B 101 184304). In the limit of weak system-bath coupling, our results reduce to the one from the quantum master equation.

We further the connection between information theory and statistical mechanics by developing a thermodynamic approach to quantum error correction. Our method of protecting a code space of quantum bits from interference involves realizing it as a thermo-equilibrium subspace in the Hilbert space of a quantum statistical model.
