Szilard engine revisited; information from time forward and backward process

Abstract

We derive the work performed in the Szilard engine (SZE) by using dissipative work formula of non-equilibrium thermodynamics developed in Kawai et al. Phys. Rev. Lett. 98, 080602 (2007). The work is described as the difference of probability distributions of measurement outcomes of the time forward and the backward process.
