Description
Book SynopsisQuantum physics allows entirely new forms of computation and cryptography, which could perform tasks currently impossible on classical devices, leading to an explosion of new algorithms, communications protocols and suggestions for physical implementations of all these ideas. As a result, quantum information has made the transition from an exotic research topic to part of mainstream undergraduate courses in physics. Based on years of teaching experience, this textbook builds from simple fundamental concepts to cover the essentials of the field. Aimed at physics undergraduate students with a basic background in quantum mechanics, it guides readers through theory and experiment, introducing all the central concepts without getting caught up in details. Worked examples and exercises make this useful as a self-study text for those who want a brief introduction before starting on more advanced books.

Trade Review'Each chapter is clearly written and provides exercises and suggestions for further reading. It is an excellent guide for anyone studying the challenging area of quantum computing.' Mircea Dragoman, Optics and Photonics News (osa-opn.org)
'… newcomers will enjoy that each chapter ends with a section suggesting further reading for each topic and a few exercises. A nice feature is that it makes many references to common experimental techniques, from which a theoretician may profit. It is recommendable as a first overview to students and scientists with a little background in quantum mechanics.' Zentralblatt MATH
