Information theory lies at the heart of modern technology, underpinning all communications,
networking, and data storage systems. This book sets out, for the first time, a
complete overview of both classical and quantum information theory. Throughout, the
reader is introduced to key results without becoming lost in mathematical details.
The opening chapters deal with the basic concepts and various applications of
Shannon’s entropy. The core features of quantum information and quantum computing
are then presented. Topics such as coding, compression, error correction, cryptography,
and channel capacity are covered from both classical and quantum viewpoints. Employing
an informal yet scientifically accurate approach, Desurvire provides the reader with
the knowledge to understand quantum gates and circuits.
