Considering the influence of collective-dephasing (C-D) noise and collective-rotation (C-R) noise, by utilizing controlled-NOT operation, controlled-Z operation and other unitary operations, we proposed the fault-tolerant quantum protocols to realize the quantum anonymous communication against C-D noise and C-R noise, respectively. Correctness analysis shows that the encrypted quantum states can not be affected by the collective noise. Security analysis shows that the protocols can ensure the anonymity of the sender and receiver and privacy of quantum information. |
