摘要/Abstract

摘要： 为进一步研究三方远程态制备(TRSP), 提出了一种不同于已有TRSP 类型的新方案。该方案为受控三方循环远程态制备的一个推广, 且可修改为一个双向与一个单向受控远程态制备的混合方案。该方案给出了十粒子纠缠信道的产生方法, 并指出在监控者的控制下, 三方中的任何两方都能联合为第三方制备一个任意单粒子态。所提方案融合了受控远程态制备和联合远程态制备的思想, 有较高的安全性, 且所采用的前馈测量策略使得其成功的概率为100%。此外, 该方案所涉及的受控非门、Hadamard 门和Pauli 门以及单粒子测量在现代技术下是可以物理实现的。

Abstract: In order to further investigate the tripartite remote state preparation (TRSP), a novel scheme different from the existing TRSP types is put forward, which is an extension of the controlled three-party cyclic remote state preparation, and can be modified into a mixed scheme of a bidirectional controlled remote state preparation and a unidirectional one. In this scheme, the generation method of ten-particle entangled channel is given, and it is pointed out that under the control of the supervisor, any two of the three parties can jointly prepare an arbitrary single particle state for the third party. The proposed scheme integrates the idea of controlled remote state preparation and joint remote state preparation, and has high security. Moreover, the feed-forward measurement strategy adopted in the scheme makes its success probability 100%. In addition, the controlled-NOT gate, Hadamard gate and Pauli gate as well as single-particle projective measurement involved in this scheme can be realized physically in modern technology.

Key words: quantum communication, controlled remote state preparation, joint remote state preparation; ten-particle entangled state, feed-forward measurement strategy
