| 摘 要： | 考虑了在位于充满Kerr介质的腔中,一对纠缠的二能级原子之一与非简并双光子的相互作用,当该原子离开腔被作选测性测量时,分析测量后光场的量子性质,研究结果表明,在纠缠度一定时,Kerr效应使光场平均光子数的崩塌回复周期减小,光场的二阶相干度减弱,使Cauchy-Schwartz不等式关联程度减弱.

| Abstract: | Based on the model that one of the two entangled two-level atoms interacts with the non-degeneration two-photon cavity filled with Kerr medium, the influence of the Kerr effect on the atom and the light is studied such as the average photon numbers, the degrees of second-order coherence and the Cauchy-Schwartz inequality. After selectively detection on one of the atoms at certain particular entanglement degree, it is found that the period of the collapse and revival of the average photon numbers, the degrees of second-order coherence of the lights,and the Cauchy-Schwartz inequality are influenced evidently by the Kerr effect. |
