摘要
Three different approaches for deriving mutual information via thermodynamics are presented, where the temperature-dependent energy is given by (a) beta epsilon = -ln[P(X, Y)], (b) beta epsilon = -ln[P(Y|X)] or (c) beta epsilon = -ln[P(X|Y)]. All approaches require the extension of the traditional physical framework and the modi. cation of the second law of thermodynamics. A realization of a physical system with an effective temperature-dependent Hamiltonian is discussed and followed by a suggestion of a physical information-heat engine.
