Transitions from Digital Communications to Quantum Communications: Concepts and Prospects

This book addresses the move towards quantum communications, in light of the recent technological developments on photonic crystals and their potential applications in systems.

The authors present the state of the art on extensive quantum communications, the first part of the book being dedicated to the relevant theory; quantum gates such as Deutsch gates, Toffoli gates and Dedekind gates are reviewed with regards to their feasibility as electronic circuits and their implementation in systems, and a comparison is performed in parallel with conventional circuits such as FPGAs and DSPs. The specifics of quantum communication are also revealed through the entanglement and Bell states, and mathematical and physical aspects of quantum optical fibers and photonic crystals are considered in order to optimize the quantum transmissions.

These concepts are linked with relevant, practical examples in the second part of the book, which presents six integrated applications for quantum communications.
