量子通信是一项涉及量子力学和物质量子特性的新型通信技术,具有高效性和在理论上的无条件安全性等特性,使其在电子通信、金融安全和军事工业等领域有着广泛的应用前景。为了从实践应用的角度讨论量子通信,本文讨论基于Greenberger-Horne-Zeilinger (GHZ)概率信道的远程制备三比特量子态的方案并以单量子比特为例,通过IBM量子实验平台进行量子系统隐形传态实验,验证该系统的保真度为0.819。远程利用量子计算机进行线路模拟仿真的实验,为今后进一步理论和实践研究做好铺垫。

Quantum communication is a new communication technology,involving quantum mechanics and the quantum properties of matter. In terms of theory,quantum communication has the property of unconditional security and effectiveness,making itself extensive application prospect on electronic communication,financial security,military industry and so on. In order to discuss quantum communication from the perspective of practical application,the theoretical scheme of remote state preparation of three-qubit based on Greenberger-Horne-Zeilinger( GHZ) probability channel was discussed. And the results obtained in one-qubit quantum system teleportation experimental was tested on IBM 5-qubit quantum computer prototypes,and the fidelity of the system was verified to be 0.819. In addition,the influence of amplitude damping noise on the remote state preparation was discussed,and the fidelity of amplitude damping single bit channel was analyzed to obtain the influence of different values of parameters on the remote state preparation results.This remote use of quantum computer for circuit simulation experiments paves the way for further theoretical and practical research.
