We suggest that the framework of quantum information theory, which has been
developing rapidly in recent years due to intense activity in quantum
computation and quantum communication, is a reasonable starting point to study
non-equilibrium quantum statistical phenomena. As an application, we discuss
the non-equilibrium quantum thermodynamics of black hole formation and
evaporation.Comment: 20 pages, LaTeX with elsart.cls, 8 postscript figures. Special issue
