外场驱动对Tavis-Cummings模型中量子态保真度的影响

Effect of external field on the fidelity of quantum states in the two-atom Tavis-Cummings model

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.通过数值分析,研究了外场以及特定初态下原子间偶极-偶极相互作用对量子态保真度的影响.

The fidelities of quantum states in the two-atom Tavis-Cummings model where the atoms are driven by an external classical field are derived. The influence of the external field and the dipole-dipole interaction of the atoms in a special initial state on the fidelity is discussd.
