Definitely one of the best books on PHYSICS of quantum information and this subject. If you are in the field of Quantum Information and Computing you probably know that it lies on intersection of Physics (Quantum Mechanics), Computer Science (Complexity and Algorithms, Cryptography) and Mathematics (Vector spaces, Linear Algebra, Number Theory...) This one is exceptional for physics of quantum information and also for describing all important ideas behind 'strange things' that exist in quantum mechanics. Authors have properly described all experiments and ideas on quantum information, quantum cryptography and teleportation. This book assumes that you have some knowledge on quantum mechanics or basic concepts about this subject. If you have mathematical background and you want to know how those thing are made physically, you will not regret for buying this book!

You could use this book as a first if you have a general idea
of basic concepts in quantum theory. It is a collection of
very nicely written tutorials. They are done by authorities in the field, and cover the main trends. I especially liked Jozsa's
chapter on quantum algorithms. By now there are also good textbooks that can get you started from scratch, such as Hirvensalo, or Nielsen-Chuang. If you have trouble getting hold the original journal articles, World Scientific just came out with a collection of major papers on quantum computation and quantum information, isbn 9810241178. It includes the full text [reprinted] of some of the papers which are cited in the present book; quite a few by the very same authors. That is a big help, as the papers in the subject are scattered and spread out over many different journals, and it might be hard to know where to start when
logging into the arXiv.

I read this books in all most 4 nites, and found it excellent to clear many dark concepts of quantum physics. I hardly recommended it to friends all over the world.
