Quantum Communication Scheme Using Non-symmetric Quantum Channel

摘要

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.
