Maxwell's Demon, Szilard's Engine and Quantum Measurements
Abstract
Description
We propose and analyze a quantum version of Szilard's ``one-molecule engine.'' In particular, we recover, in the quantum context, Szilard's conclusion concerning the free energy ``cost'' of measurements: $ΔF \geq k_B T\ln2$ per bit of information.
