文摘We propose a quantum superdense coding secure communication scheme by using GHZ state.This scheme combines the ideas of quantum superdense coding and sequence transmission.Its distinct advantage is high source capacity.In addition,in checking eavesdropping,we need not to destroy quantum entanglement.
