Abstract :
In this paper, we proposed a convert communication protocol using quantum dense coding with EPR maximally entangled states. The ordered EPR pairs sequence is divided into two particle sequences: Sequence 2 and Sequence 1. The two sides of communication insure the security of the Sequence 2 by the transmission latency. After the receiver gets both of the two ordered EPR pairs sequence and their initial Bell states, he can read out the secret message. Different from classical convert communication systems, our quantum convert communication system could effectively detect eavesdropping and achieve unconditional security.
