Quantum communication, which utilizes quantum entanglement and no-cloning theorem, can potentially achieve tasks that are impossible by a current communication technology. So far, secure key distribution between two distant users has been mainly studied and becomes ready for application. Quantum communication has, however, much more potential. For example, multi-party cryptographic protocols, super dense coding, and distributed quantum computation are possible with the help of quantum media transfer. In this research project, we will study this kind of multi-party quantum communications and quantum interfaces from theoretical and experimental aspects.
