- Abstract
In this paper, the N-particle GHZ states are used as quantum resources for multiparty quantum secure direct communication. Three new multiparty quantum secure direct communication protocols are proposed, which are based on the ideal quantum channels, the collective-dephasing noise channels and the collective-rotation noise channels, respectively. With the help of logical quantum states, the latter two protocols can be immune to the collective-dephasing noise and the collective-rotation noise, respectively. The security analysis shows that the Trojan horse attacks and the teleportation attack are automatically resisted because of the one-way transmission of quantum states in quantum channels. The use of the decoy states (or decoy logical qubits) also makes the three protocols secure against other kinds of attacks. Moreover, all of them have no information leakage problem.
