2018 The-Theory-of-Quantum-Information.pdf

This is a book on the mathematical theory of quantum information, focusing on a formal presentation of definitions, theorems, and proofs. It is primarily intended for graduate students and researchers having some familiarity with quantum information and computation, such as would be covered in an introductory-level undergraduate or graduate course, or in one of several books on the subject that now exist. Quantum information science has seen an explosive development in recent years, particularly within the past two decades. A comprehensive treatment of the subject, even if restricted to its theoretical aspects, would certainly require a series of books rather than just one. Consistent with this fact, the selection of topics covered herein is not intended to be fully representative of the subject. Quantum error correction and fault-tolerance, quantum algorithms and complexity theory, quantum cryptography, and topological quantum computation are among the many interesting and fundamental topics found within the theoretical branches of quantum information science that are not covered in this book. Nevertheless, one is likely to encounter some of the core mathematical notions discussed in this book when studying these topics.
