SEMINAR      Thursday 30 June 2005 - h. 15:00  Auditorium B. Touschek     R. Fazio (Scuola Normale Superiore - Pisa) Entanglement in Quantum Information Abstract A quantum mechanical system possesses additional correlations that do not have a classical counterpart. Besides its fundamental interest, a great deal of attention in the understanding of entanglement has been brought forth by its role in quantum information.    Entanglement is believed to be the main ingredient to realize  new schemes of computation and communications. Two of the most celebrated examples are quantum teleportation and entanglement-based quantum key distribution protocol.    I will present a general overview of these topics as well as some connections between quantum information and other areas (condensed matter for example) based on the study of quantum entanglement.
