Descrizione articolo

Riassunto:

The first handbook to provide a comprehensive inter-disciplinary overview of QCC. It includes peer-reviewed definitions of key terms such as Quantum Logic Gates, Error Correction, Quantum Dots, Nuclear Magnetic Resonance, Quantum Holography, and Quantum Cryptography. There are also reports on major application areas, principles of QCC, and targets, benchmarks and challenges, making this an invaluable buy for any university department with this exciting new topic in its curriculum. It equally provides a unique overview of a fast-moving and multidisciplinary topic for researchers, students, lecturers, and even the interested amateur.
