Abstract: (APS)
A sufficient condition for the quantum entropy, −Tr(ρlnρ), to be nondecreasing under a tracepreserving positive linear map is that the "totally random" state, ρ∝1, be stationary. It is argued that this condition will be satisfied by the quantum system consisting of the region external to one or more black holes. This would explain why a "generalized second law of thermodynamics" appears to hold in the presence of black holes.References(12)
