摘要
We propose a new quantum private communication protocol, in which the anonymity of the sender and the privacy of the quantum information are perfectly protected except with exponentially small probability. Furthermore, this protocol uses single particles to construct anonymous entanglement instead of multipartite entangled states, and thus it reduces quantum resources compared with the previous work.
