 The aim of this little book is to convey three principal developments in the evolution of modern information theory: Shannon's initiation of a revolution in 1948 by his interpretation of the Boltzmann entropy as a measure of information yielded by an elementary statistical experiment and basic coding theorems on storage and optimal transmission of messages through noisy communication channels; the influence of ergodic theory in the enlargement of the scope of Shannon's theorems through the works of McMillan, Feinstein, Wolfowitz, Breiman, and others, and its impact on the appearance of the KolmogorovSinai invariant for elementary dynamical systems; and finally, the more recent work of Schumacher, Holevo, Winter, and others on the role of von Neumann entropy in the quantum avatar of the basic coding theorems when messages are encoded as quantum states, transmitted through noisy quantum channels and retrieved by generalized measurements. This revised second edition has a chapter devoted to quantum error correction theory that shows how information in the form of quantum states can be made to tunnel through a noisy environment.
