| Abstract: | A theoretical quantum communication scheme based on entanglement
swapping and superdense coding is proposed with a 3-dimensional
Bell state and 2-dimensional Bell state function as quantum channel.
quantum key distribution and quantum secure direct communication can be simultaneously accomplished in the scheme. The
scheme is secure and has high source capacity. At last, we
generalize the quantum communication scheme to d-dimensional quantum channel. |
