    "abstract": "A Maxwell\u0027s demon is a device that gets information and trades it in for\nthermodynamic advantage, in apparent (but not actual) contradiction to the\nsecond law of thermodynamics. Quantum-mechanical versions of Maxwell\u0027s demon\nexhibit features that classical versions do not: in particular, a device that\ngets information about a quantum system disturbs it in the process. In\naddition, the information produced by quantum measurement acts as an additional\nsource of thermodynamic inefficiency. This paper investigates the properties of\nquantum-mechanical Maxwell\u0027s demons, and proposes experimentally realizable\nmodels of such devices.",
