Abstract

A multiparty bidirectional quantum secure communication protocol is proposed with two-photon entanglement and quantum dense coding, in which the qubit transmission forms a closed loop. In this scheme, each user performs the unitary operations according to his secret information to encode the exchanged messages into the particle sequences. Then, each participant can extract the other participants’ secret messages by implementing Bell measurements on the encoded particles. Thus all the users realize the direct communication simultaneously. Finally, the security analysis shows that our scheme is secure.
