摘要：

The universal blind quantum computation (UBQC) is a scheme to allow a client to delegate a computation to a remote server while concealing the input, output and algorithm. However, the qubit errors are inevitable in the practical application. In this paper, a fault-tolerant quantum error correction code preparation protocol with weak coherent pulses is proposed for fault-tolerant UBQC. Furthermore, the epsilon-correctness and epsilon-blindness of the protocol are fully proven. The simulation results show that the required number of pulses in our protocol is much less than that of the remote blind qubit state preparation protocol with two decoy states in case of the same probability of successful preparation, and is closer to asymptotic case.
