Quantum information theory has revolutionised our view on the true nature of information and has led to such intriguing topics as teleportation and quantum computation. The field -- by its very nature strongly interdisciplinary, with deep roots in the foundations both of quantum mechanics and of information theory and computer science -- has become a major subject for scientists working in fields as diverse as quantum optics, superconductivity or information theory, all the way to computer engineers.

The aim of this book is to provide guidance and introduce the broad literature in all the...
