This volume presents the state of the art in the research on new possibilities for communication and computation based on quantum theory and nonlocality, as well as related directions and problems. It discusses challenging issues: decoherence and irreversibility; nonlocality and superluminosity; photonics; quantum information and communication; quantum computation.Contents:Decoherence and IrreversibilityNon-Locality and SuperluminosityPhotonicsQuantum Information and CommunicationQuantum ComputationReadership: Researchers, lecturers and PhD students in atomic physics, condensed matter physics and optics.
