This book, the
worn first-edition of which I've had on my shelf for 11
years, is the indispensable companion for anyone's journey
into that exotic terrain.
Beyond all else, I am thrilled about the inclusion of
two new chapters in the new edition, one of which I believe
goes to the very heart of the meaning of quantum theory.

‘The quantum
world is full of surprises as is the mathematical theory
that describes it. Bengtsson and Życzkowski prove to be
expert guides to the deep mathematical structure that
underpins quantum information science. Key concepts such as
multipartite entanglement and quantum contextuality are
discussed with extraordinary clarity. A particular feature
of this new edition is the treatment of SIC generalised
measurements and the curious bridge they make between
quantum physics and number theory.’

Quantum information theory is a branch of
science at the frontiers of physics, mathematics and
information science, and offers a variety of solutions
that are impossible using classical theory. This book
provides a detailed introduction to the key concepts used
in processing quantum information and reveals that quantum
mechanics is a generalisation of classical probability
theory.
The second
edition contains new sections and entirely new
chapters: the hot topic of multipartite entanglement;
in-depth discussion of the discrete structures in finite
dimensional Hilbert space, including unitary operator
bases, mutually unbiased bases, symmetric informationally
complete generalised measurements, discrete Wigner
functions and unitary designs; the Gleason and Kochen–
This
richly-illustrated book will be useful to a broad audience
of graduates and researchers interested in quantum
information theory. Exercises follow each chapter, with
hints and answers supplied.
