**Quantum Systems, Channels, Information**

**A
Mathematical Introduction**

**by****
A. S. Holevo **

The
subject of this book is theory of quantum system presented from information
science perspective. The central role is played by the concept of quantum
channel and its entropic and information characteristics. Quantum information
theory gives a key to understanding elusive phenomena of quantum world and
provides a background for development of experimental techniques that enable
measuring and manipulation of individual quantum systems. This is important for
the new efficient applications such as quantum computing, communication and
cryptography. Research in the field of quantum informatics, including quantum
information theory, is in progress in leading scientific centers throughout the
world.

This
suggests a need for a text that not only introduces the basic concepts of
quantum information theory, but also presents in detail some of its recent
achievements. The book gives an accessible, albeit mathematically rigorous and
self-contained introduction to the subject, starting from primary structures
and leading to fundamental results and to exiting open problems.
