Quantum teleportation enables the transfer of quantum states across any distance and plays a prominent role in quantum communication. In this paper, we theoretically investigate the feasibility of quantum two-qubit teleportation through a hybrid channel consisting of thermal, magnetic, and local components. To study this process, we check the success probability of quantum teleportation and address the quality of the teleported quantum state using fidelity and average fidelity concepts. Furthermore, we examine a crucial quantum aspect of the system, such as the non-Markovianity of the dynamics, by utilizing success probability witness related to the teleported state. Our findings show that this hybrid channel has a good potential to be successful in quantum teleportation.
量子隐形传态能够跨越任意距离传输量子态，在量子通信中发挥着重要作用。在本文中，我们从理论上研究了通过由热、磁和局域分量组成的混合信道实现量子两比特隐形传态的可行性。为了研究这个过程，我们通过保真度和平均保真度概念来检验量子隐形传态的成功概率，并探讨隐形传态量子态的质量。此外，我们利用与隐形传态状态相关的成功概率见证来研究系统的一个关键量子方面，比如动力学的非马尔可夫性。我们的研究结果表明，这种混合信道在量子隐形传态方面具有良好的成功潜力。
