Abstract: Information thermodynamics (overview talk)
Speaker: Masahito Ueda
Information thermodynamics incorporates quantum measurement into thermodynamics, thereby enabling one to evaluate the cost of measurement and that of information erasure in information processing of thermodynamics [1]. The total cost of measurement and information erasure resolves the paradox of Maxwell’s demon. Information thermodynamics also unifies the modern fluctuation theorem with information theory [2], leading to a rather unexpected consequence that the inclusion of the factor 1/N! in the thermodynamic entropy introduced by Gibbs (the Gibbs paradox) is equivalent to the validity of the fluctuation theorem with absolute irreversibility for gas mixing [3].
