摘要
利用全量子理论,对多光子跃迁下Polya光场与运动二能级原子相互作用系统的保真度进行了研究。分析了原子的初始状态、场模结构参数、光场最大光子数、光场参数和跃迁光子数等物理参量对系统量子态和光场量子态保真度的影响。结果表明:原子的运动速度影响系统量子态和光场量子态保真度的振荡周期;跃迁光子数选取不同,系统量子态和光场量子态的保真度表现出不同的规律。
Abstract
The fidelity in a system which is composed of a multi- photon transition moving two- level atom interacting with Polya state light is studied by means of the full quantum theory. The influences of the atomic initial state, field-mode structure parameter, the maximum photon number of the light, the optical field parameters and the values of the transitional photon number on the fidelity of the system are also analyzed .The results show that the velocity of atom effects the oscillation period of fidelity. The fidelity presents different patterns when transitional photon numbers are at some fixed values.
