摘　　要：利用量子态扩散方法研究了耦合到多模非马尔可夫玻色库的单个三能级原子的量子隐形传态保真度的动力学演化特性,并分析了不同参数对保真度的影响。结果表明,当三能级原子与强非马尔可夫环境耦合并且三能级原子初始状态处于激发态或亚稳态时,三能级原子量子隐形传态保真度拥有较长的弛豫时间及较好的鲁棒性。此外,利用外加磁场控制三能级原子的量子隐形传态,可以使得三能级原子拥有鲁棒性较好的保真度。The dynamic evolution of the fidelity of quantum teleportation in a single three-level atom coupled to a multi-mode non-Markovian bosonic environment is studied by using the quantum state diffusion method,and the effects of different parameters on the fidelity are analyzed.The results show that when the three-level atom is coupled with the strong non-Markovian environment,and the initial state of the three-level atom is in excited state or metastable state,the fidelity of quantum teleportation of three-level atoms has long relaxation time and good robustness.In addition,the external magnetic field is used to control the quantum teleportation of the three-level atom,which can make the three-level atom have a fidelity with good robustness.
