@PRL Maxwell’s Demon Meets Nonequilibrium Quantum Thermodynamics
A new implementation of a Maxwell’s demon can control entropy production in a quantum-mechanical system that is driven out of thermal equilibrium. Maxwell’s demon explores the role of information in physical processes. Employing information about microscopic degrees of freedom, this “intelligent observer” is capable of compensating entropy production (or extracting work), apparently challenging the second law of thermodynamics. In a modern standpoint, it is regarded as a feed
