1·We analysis the effect of squeezed parameter of single mode squeezed state on the fidelities.

分析了单模压缩态的压缩参数对保真度的影响。

2·The fidelities of quantum states in the two-atom Tavis-Cummings model where the atoms are driven by an external classical field are derived.

求出了原子受到外部经典场驱动时，双原子T-C模型中量子态的保真度。

3·Results show that the less the Stark shift is, which will weaken the interaction between the field and atom, and the higher the fidelities of the three systems are.

平均光子数越大，原子和光场的相互作用就越强，系统和原子的保真度就越小。
