| 量子隐形传态是通过利用纠缠态光场的量子信息传输机制，使得量子态能够在不同节点之间进行传输，而无需依赖传统的信息载体. 随着量子信息的不断发展，连续变量量子隐形传态在构建连续变量量子计算系统和量子信息网络架构方面展现出了显著的应用前景. 为了满足对量子隐形传态的多组份特性、灵活多样性以及可控性等方面日益增长的技术需求，研究者们不断提出新的理论与技术，推动着该领域稳步前进. 因此，有效构建包含多组份量子资源的量子隐形传态网络，已经成为推动量子信息领域发展的核心挑战之一. 本文提出基于一对Einstein-Podolsky-Rosen纠缠态光场和携带有高斯噪声的热光场相互耦合所得到的四组份量子资源，提出了量子隐形传态网络的多种理论构建方案，我们通过对热光场噪声的调节，可以很容易地控制量子隐形传态网络的保真度. 并深入分析了不同物理参数下，各个方案中量子隐形传态网络保真的变化规律，同时对比分析了各方案的特点及优劣势，这一系列的研究为量子隐形传态网络设计方案的进一步优化奠定了坚实基础. |

| As one of the core protocols of quantum information processing technology, quantum teleportation uses the quantum information transmission mechanism of entangled states to enable quantum states to be transmitted between different nodes without relying on traditional information carriers. With the modernization of quantum information technology, continuous-variable quantum teleportation has shown important application potential in the construction of continuous-variable quantum computing systems and quantum information network architectures. In order to meet the growing technical needs for multi-component properties, flexible diversity and controllability of quantum teleportation, researchers continue to propose new theories and technologies, which promote the continuous development of this field. Therefore, the effective construction of quantum teleportation networks containing multi-component quantum resources has become one of the core challenges to promote the development of quantum information. In this paper, we propose a four-component quantum resource based on the coupling of a pair of Einstein-Podolsky-Rosen entangled light fields and a thermal light field carrying Gaussian noise, and propose a variety of theoretical construction schemes for quantum teleportation networks, and we can easily control the fidelity of quantum teleportation networks by adjusting the noise of the thermo-optical field. The variation law of quantum teleportation network fidelity in each scheme under different physical parameters is analyzed in depth, and the characteristics, advantages and disadvantages of each scheme are compared and analyzed. The quantum teleportation network constructed in this paper has significant advantages such as a large number of nodes, abundant resource types and easy optimization, which not only provides a broader application prospect for the construction of larger-scale and more complex quantum information networks in the future, but also promotes the transformation process of quantum information technology into practical applications. |
