Quantum Bits and Quantum Secrets

Download or read book Quantum Bits and Quantum Secrets written by Oliver Morsch and published by John Wiley & Sons. This book was released on 2008-03-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise, "no-frills" introduction to quantum computation and quantum cryptography for non-experts. Rather than concentrating on stories about scientists and philosophical concepts, it provides a step-by-step approach to quantum information. Starting from the idea of quantum cryptography, it presents the basic principles of quantum mechanics and explains how this can be used to make cryptography absolutely secure against eavesdropping. Subsequently, the most important quantum algorithms are explained and technical problems in realizing quantum computers are discussed, followed by a presentation of recent experiments -- some of which are found here in a textbook for the first time. Easily accessible for undergraduates and graduates -- especially those studying subjects other than physics -- who need an introduction to this rapidly developing topic.
