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 book...The 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.
