Classical information theory

Abstract

Shannon entropy is the key-notion of classical information. It provides the statistical measure of information associated with states ρ. Since dynamical aspects shall not be treated at all, we would just talk about probability distributions p instead of physical states ρ. For comparability with Q-information theory of Chap. 10 , however, we keep talking about states ρ of classical systems. Typically, we use heuristic proofs though corner stones of the exact derivations will fairly be indicated. © 2011 Springer-Verlag Berlin Heidelberg.
