| 摘 要： | 利用全量子理论及量子信息保真度理论，研究了薛定谔猫态光场与玻色爱因斯坦凝聚原子相互作用系统中，量子态保真度随时间的演化特性.讨论了光场强度和玻色爱因斯坦凝聚原子间的耦合强度对量子态保真度的影响.结果表明：光场强度可调制量子态的保真效果，而原子间的耦合常数主要影响量子态保真度的振荡频率.

| Abstract: | The evolution characteristics of quantum state fidelity in an interacting system of S-cat state optical field and Bose-Einstein condensate have been studied by means of quantum fidelity and the influence of the light field intensity and interaction among atoms of Bose-Einstein condensate on the quantum state fidelity have been discussed. The results indicate that the optical field can modulate the fidelities of quantum states in the system of interaction, whereas the interaction constants among atoms influence mainly the oscillation frequency of the fidelity of quantum state of system. |
