Abstract: The logical relationship between Bell state and single quantum bit logic gate is used in quantum multi-proxy signature protocol. Multiple-proxy signature operation is realized simply and efficiently. The protocol is not restricted by the number and sequence of proxy signers, and the operation is simple. It can be realized completely in the existing technical conditions. The correctness and security analysis of the protocol shows that it is a secure and achievable quantum multi-proxy signature protocol.
