含原子运动的Jaynes-Cummings模型中的量子态保真度

摘要

研究了相干光场作用下的含原子运动的Jaynes-Cummings模型中体系量子态保真度，讨论了不同的原子初态条件下，原子的运动和场模结构对体系中的量子态保真度的影响。结果表明：在一定的条件下，原子运动的速度和场模结构参数可调制相互作用体系的量子态保真度。%The fidelities of quantum states of system in Jaynes-Cummings model containing atomic motion under action of coherent field are studied. The influence of atomic motion and the field mode structure on the fidelities of quantum states of system in different atomic initial states is discussed. The result indicates that both the atomic motion and the field mode structure can modulate the fidelities of quantum states in the system of interaction.
