Necessity of Feedback Control for the Quantum Maxwell Demon in a Finite-Time Steady Feedback Cycle

Statistical Mechanics 2022-09-08 v2 Quantum Physics

Abstract

We revisit quantum Maxwell demon in thermodynamic feedback cycle in the steady-state regime. We derive a generalized version of the Clausius inequality for a finite-time steady feedback cycle with a single heat bath. It is shown to be tighter than previously known ones, and allows us to clarify that feedback control is necessary to violate the standard Clausius inequality.
