This graduate textbook provides a unified view of quantum information theory. Clearly explaining the necessary mathematical basis, it merges key topics from both information-theoretic and quantum- mechanical viewpoints and provides lucid explanations of the basic results. Thanks to this unified approach, it makes accessible such advanced topics in quantum communication as quantum teleportation, superdense coding, quantum state transmission (quantum error-correction) and quantum encryption.
Since the publication of the preceding book Quantum Information: An Introduction, there...

This book explains the group representation theory for quantum theory in the language of quantum theory. Group representation theory is a fundamental mathematical tool for quantum theory, in particular, for quantum information. Quantum theory requires so many aspects of group representation theory. There are so many books for group representation theory. Most of books based on the mathematical viewpoint focus only on a part of group representation used for quantum theory. In particular, they do not focus on the projective representation while any physical realizable symmetry is written as...

Recently, quantum information theory has been developing through a fusion of results from various research fields. This requires that understanding of basic results on diverse topics, and derived from different disciplinary perspectives, is required for appreciating the overall picture. Intended to merge key topics from both the information-theoretic and quantum- mechanical viewpoints, this graduate-level textbook provides a unified viewpoint of quantum information theory and lucid explanations of those basic results, so that the reader fundamentally grasps advances and challenges. For...
