Quantum processing and communication is emerging as a challenging technique at the beginning of the new millennium. This revised and enlarged edition provides an up-to-date insight into the current research of quantum superposition, entanglement, and the quantum measurement process - the key ingredients of quantum information processing. The contributions - written by leading experts - bring together the latest results in quantum information as well as addressing all the relevant questions.Die Quanteninformationstheorie ist eine rapide wachsende und herausfordernde Technologie zu Beginn dieses neuen Jahrtausends. Die mögliche Realisierung eines Quantencomputers innerhalb der nächsten 20 Jahre wäre ein revolutionärer Fortschritt in der Datenverarbeitung und Kryptografie. In diesem Buch berichten Experten verschiedener physikalischer Gebiete über die neuesten Erkenntnisse auf dem Gebiet der Quanteninformationsverarbeitung. Die Autoren liefern einen interdisziplinären Überblick über die letzten drei Jahre der Forschungsaktivitäten der Quanteninformationsverarbeitung. Vom deutschen Bundesministerium für Bildung und Forschung gefördert, nahmen an diesem Projekt 40 Forschergruppen aktiv teil.
Thomas Beth studied mathematics, physics and medicine. He received his Ph.D. in 1978 and his Postdoctoral Lecturer Qualification (Dr.-Ing. habil.) in informatics in 1984. From a position as Professor of computer science at the University of London he was apppointed to a chair of informatics at the University of Karlsruhe. He also is the director of the European Institute for System Security (E.I.S.S.). In the past decade he has built up a research center for quantum information at the Institute for Algorithms and Cognitive Systems (IAKS).
Gerd Leuchs studied physics and mathematics at the University of Cologne and received his Ph.D. in 1978. After two research visits at the University of Colorado, Boulder, he headed the German Gravitational Wave Detection Group from 1985 to 1989. He then went on to be the technical director of Nanomach AG in Switzerland for four years. Since 1994 he holds the chair for optics at the Friedrich-Alexander-University of Erlangen-Nuremberg, Germany. His fields of research span the range from modern aspects of classical optics to quantum optics and quantum information.

Rezensionen
"This collection representing state-of-the-art research in a number of important directions, with a nice balance between theory and experiment, is a worthy contribution to the literature. Researchers and graduate students working in any aspect of quantum information science would find this collection a very useful and readable summary of the work." (Lloyd C. L. Hollenberg, Centre for Quantum Computer Technology, Melbourne, about the first edition)
