Abstract

Abstract

Even attacks by quantum computer can be theoretically discovered if utilizing quantum communication protocols. Compared with entangled states, the Continuous Variable (CV) Gaussian coherent state is easier to be prepared. The schemes of quantum communication network based on coherent state will be more economical and practical. A Measurement-Device-Independent (MDI) Cluster state quantum communication network scheme by using coherent state is proposed. Quantum Secret Sharing (QSS) and Quantum Conference (QC) protocols can be implemented in this network. A linear Cluster state scheme is poposed to implement t-out-of-n QSS protocol, a star Cluster state scheme to implement four-user QSS protocol and QC protocol. The entanglement-based CV MDI scheme is used to analyze the relationship between the key rates and transmission distance for each symmetric and asymmetric protocol. The presented schemes provide a concrete reference for establishing CV MDI quantum QSS and QC protocol in quantum networks by using coherent state.
