Benjamin Schumacher, Michael WestmorelandCambridge University Press, 3/25/2010EAN 9780521875349, ISBN10: 052187534XHardcover, 482 pages, 24.6 x 18.9 x 2.4 cmLanguage: EnglishA new and exciting approach to the basics of quantum theory, this undergraduate textbook contains extensive discussions of conceptual puzzles and over 800 exercises and problems. Beginning with three elementary 'qubit' systems, the book develops the formalism of quantum theory, addresses questions of measurement and distinguishability, and explores the dynamics of quantum systems. In addition to the standard topics covered in other textbooks, it also covers communication and measurement, quantum entanglement, entropy and thermodynamics, and quantum information processing. This textbook gives a broad view of quantum theory by emphasizing dynamical evolution, and exploring conceptual and foundational issues. It focuses on contemporary topics, including measurement, time evolution, open systems, quantum entanglement, and the role of information.1. Bits and quanta2. Qubits3. States and observables4.

Error correctionAppendixesIndex.'This is a fantastic book, with one of the authors no less than the very inventor of the word and idea of a qubit. When I opened the book for the first time, I found I couldn't stop reading through it and working out some of the problems. ... There's no book out there I would recommend more for learning the mechanics of this quantum world.' Chris Fuchs, Perimeter Institute for Theoretical Physics Show more
