QUANTUM SYSTEMS, CHANNELS, INFORMATION (REV. AND EXPANDED) (TEXTS AND MONOGRAPHS IN THEORETICAL PHYSICS) (2ND ED.)

Written by one of the founding fathers of Quantum Information, this book gives an accessible (albeit mathematically rigorous), self-contained introduction to quantum information theory. The central role is played by the concept of quantum channel and its entropic and information characteristics. In this revised edition, the main results have been updated to reflect the most recent developments in this very active field of research.
