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.

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 example, advanced topics in quantum communication such as quantum teleportation, superdense coding, quantum state transmission (quantum error-correction), and quantum encryption especially benefit from this unified approach. Unlike earlier treatments, the text requires knowledge of only linear algebra, probability theory, and quantum mechanics, while it treats the topics of quantum hypothesis testingand the discrimination of quantum states, and quantum channel coding (message transmission) with the minimal amount of math needed to convey their essence. Solving the more than 240 exercises provides readers with practice that not only enriches their knowledge of quantum information theory, but also can equip them with the techniques necessary for pursuing their own research in this field.

Rezensionen
From the reviews: "The book under review is, without a doubt, the most comprehensive textbook to date on quantum information theory. ... This comprehensive and theorem-heavy approach makes the book a valuable reference for those working in the field of quantum information. ... This book could be used in a graduate course in quantum information theory ... . an extremely helpful work, and I am glad that it is available." (Todd A. Brun, Mathematical Reviews, Issue 2007 b)
"Quantum Information: An Introduction by Masahito Hayashi provides much more than merely an introduction to this active area of study. The text is a thorough mathematical foundation upon which graduate students and early career researchers alike can build the knowledge and skills required to pursue their own research in the field. ... I will be gladly recommending this text to any researcher wishing to enter the field, from graduate student through to professor." (N. Oxtoby, Contemporary Physic, Vol. 49 (01),January-February, 2008)
