Abstract

In order to solve the problem of multi-party quantum communication, this paper first proposed a method to construct a ten-particle entangled state, and then constructed a 3n+1-particle entangled state. Secondly, this paper proposed a tripartite controlled cyclic remote preparation protocol using ten-particle entangled state as quantum channel. The protocol showed that under the control of the supervisor David, Alice could remotely prepare an arbitrary single-particle state for Bob, Bob could prepare an arbitrary single-particle state on Charlie's site, and Charlie could also remotely prepare an arbitrary single-particle state for Alice. Furthermore, by using the 3n+1-particle entangled state, the paper generalized this cyclic protocol to the case of arbitrary n-party controlled cyclic remote state preparation. In the process of remote state preparation, each sender made full use of their own information and feedforward strategy to construct an appropriate measurement base. By using classical communication and local operation, the scheme successfully realized remote preparation of arbitrary single-particle states.
