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. Employ- ing an informal yet scientifically accurate approach, Desurvire provides the reader with the knowledge to understand quantum gates and circuits. Highly illustrated, with numerous practical examples and end-of-chapter exercises, this text is ideal for graduate students and researchers in electrical engineering and computer science, and also for scientists and practitioners in the telecommunications industry.
