摘要

在多个用户之间有效传播信息是实现大规模量子通信网络的目的。本文介绍了具有实振幅和复相位信息的单量子比特、双量子比特和三量子比特的组播协议。这些协议使用格林伯格-霍恩-蔡林格复合态作为共享信道来实现。联合远程状态准备是完成量子组播的主要方法。同时，在 IBM 量子平台上对这些方案进行了量子态层析。获得的状态与目标状态进行了保真度比较。对通信效率和噪声影响的分析表明，我们的协议在复杂系数的情况下具有优势。

Quantum multicast based on joint remote state preparation

Effective propagation of information among multiple users is the purpose of realizing large-scale quantum communication networks. In this paper, multicast protocols for any single, two and three qubits with real amplitude and complex phase information are presented. They were realized using a composite of Greenberger–Horne–Zeilinger states as shared channels. Joint remote state preparation was the main method for completing quantum multicast. At the same time, quantum state tomography of the schemes was carried out on the IBM Quantum platform. The obtained states were compared with the target states by fidelity. The analysis of communication efficiency and noise effects shows that our protocol has advantages in the case of complex coefficients.
