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 have been tremendous strides in the field of
quantum information. In particular, the following topics - all of which
are addressed here - made seen major advances: quantum state
discrimination, quantum channel capacity, bipartite and multipartite
entanglement, security analysis on quantum communication, reverse
Shannon theorem and uncertainty relation.
With regard to the analysis of quantum security, the present book
employs an improved method for the evaluation of leaked information and
identifies a remarkable relation between quantum security and quantum
coherence. Taken together, these two improvements allow a better
analysis of quantum state transmission. In addition, various types of
the newly discovered uncertainty relation are explained.
Presenting a wealth of new developments, the book introduces readers to
the latest advances and challenges in quantum information.
To aid in understanding, each chapter is accompanied by a set of
exercises and solutions.
