Quantum Information, 2 Volume Set: From Foundations to Quantum Technology Applications

This comprehensive textbook on the rapidly advancing field introduces readers to the fundamental concepts of information theory and quantum entanglement, taking into account the current state of research and development. It thus covers all current concepts in quantum computing, both theoretical and experimental, before moving on to the latest implementations of quantum computing and communication protocols. It contains problems and exercises and is therefore ideally suited for students and lecturers in physics and informatics, as well as experimental and theoretical physicists in academia and industry who work in the field of quantum information processing.The second edition incorporates important recent developments such as quantum metrology, quantum correlations beyond entanglement, and advances in quantum computing with solid state devices.

Dagmar Bru? graduated at RWTH University Aachen, Germany, and received her PhD in theoretical particle physics from the University of Heidelberg in 1994. As a research fellow at the University of Oxford she became interested in quantum information. Another European fellowship at ISI Torino, Italy, followed. While being a research assistant at the University of Hannover she completed her habilitation. Since 2004 Professor Bru? has been holding a chair at the Institute of Theoretical Physics at Heinrich-Heine-University D?sseldorf, Germany. Her research pertains to theoretical aspects of quantum information processing.

Gerd Leuchs studied physics and mathematics at the University of Cologne, Germany, and received his Ph.D. in 1978. After two years at the University of Colorado in Boulder, USA, he headed the German gravitational wave detection group from 1985 to 1989. He became technical director at Nanomach AG in Switzerland. Since 1994 Professor Leuchs has been holding the chair for optics at the University of Erlangen-Nuremberg, Germany. In 2009 he was a founding director of the Max Planck Institute for the Science of Light. He is visiting professor at the University of Ottawa. His fields of research span the range from modern aspects of classical optics to quantum optics and quantum information.
