| 摘 要： | 利用全量子理论研究了存在腔耗散的大失谐 Jaynes-Cumming(J-C) 模型中量子态保真度,讨论了初始平均光子数一定的情况下腔的耗散系数对量子态保真度的影响,以及当腔的耗散一定的情况下初始光场的平均光子数对量子态保真度的影响.结果表明:腔的耗散和光场的初始平均光子数对原子和原子---光场系统的保真度的影响都很明显.

| Abstract: | The fidelities of quantum states of system in Jaynes-Cummings model considering the dissipation of cavity were studied by using the complete quantum theory.The influences of the cavity damping constant and the numerical value of initial mean photon number on the fidelities of quantum states was discussed.It was found that both of them affect the fidelities of atom and of atom-cavity system obviously. |

| Keywords: | fidelity of quantum states damping constant Jaynes-Cummings mode large detuning |
