Böcker av Masahito Hayashi

This book explains the group representation theory for quantum theory in the language of quantum theory.

Giving a unified view of quantum information theory, the second edition explains the mathematical basis, merges topics from information-theoretic and quantum-mechanical viewpoints and explains the basic results, aiming to clarify, for example, quantum teleportation, superdense coding, quantum state transmission and quantum encryption.

This book is the first one addressing quantum information from the viewpoint of group symmetry. This book treats optimal information processes including quantum state estimation, quantum state cloning, estimation of group action and quantum channel etc.

This book presents the basics of quantum information, e.g., foundation of quantum theory, quantum algorithms, quantum entanglement, quantum entropies, quantum coding, quantum error correction and quantum cryptography. As important quantum protocols, this book contains quantum teleportation, quantum dense coding, quantum data compression.
