Quantum cryptography based on quantum dots
Network protocols are formulated for the phase coding and correlated photon pairs quantum cryptosystems. These protocols allow to lift the restriction on the distance between the two legitimate users imposed by the transmission loss in optical fiber. A single photon source and a source of correlated photon pairs based on quantum dots are proposed. PACS: 03.65.Bz, 89.70,+c, 42.50.Wm
