    "abstract": "Quantum correlations between two particles show non-classical properties\nwhich can be used for providing secure transmission of information. We present\na quantum cryptographic system, in which users store particles in quantum\nmemories kept in a transmission center. Correlations between the particles\nstored by two users are created upon request by projecting their product state\nonto a fully entangled state. Our system allows for secure communication\nbetween any pair of users who have particles in the same center. Unlike other\nquantum cryptographic systems, it can work without quantum channels and is\nsuitable for building a quantum cryptographic network. We also present a\nmodified system with many centers.",
