This is an excellent introductory book, ideal for a final year UK undergraduate course in QI It is the best one I have found so far and provides an excellent grounding foradvanced books like Nielsen and Chuang for example Professor David Toms, Newcastle University Stephen Barnett s Quantum Information is a concise and remarkably readable account of most of the developments in the field His book touches on almost all aspects of quantum information and quantum computing, including communication and measurement theory, entanglement, and computing algorithms An impressive bookThe engaging introductory chapters, extensive problem sets, and exhaustive appendices result in a textbook highly recommended for a one semester course on quantum information at the advanced undergraduate or graduate level Physics Today A carefully written book, well suited as a textbook, strong on pedagogy, accomplishes a lot as a very accessible first introduction to quantum information American Journal of Physics an impressive book The engaging introductory chapters, extensive problems sets, and exhaustive appendices result in a textbook that I highly recommend for a one semester course on quantum information at the advanced undergraduate or graduate level M Suhail Zubairy, Physics Today A nice introduction to quantum information Mathematical ReviewsQuantum information the subject is a new and exciting area of science, which brings together physics, information theory, computer science and mathematics Quantum Information the book is based on two successful lecture courses given to advanced undergraduate and beginning postgraduate students in physics The intention is to introduce readers at this level to the fundamental, but offer rather simple, ideas behind ground breaking developments including quantum cryptography, teleportation and quantum computing The text is necessarily rather mathematical in style, but the mathematics nowhere allowed priority over the key physical ideas My aim throughout was to be as complete and self contained but to avoid, as far as possible, lengthy and formal mathematical proofs Each of the eight chapters is followed by about forty exercise problems with which the reader can test their understanding and hone their skills These will also provide a valuable resource to tutors and lectures
