【摘要】 研究了能量损耗腔中,两纠缠二能级原子与单模辐射场相互作用过程中原子的纠缠动力学.结果表明双纠缠原子的纠缠度演化特性决定于初始两原子间的纠缠度、纠缠形式、腔场的平均光数、腔场的衰变系数.当原子初始处于一特定纠缠态时,其纠缠度可以放大,并且不受腔场损耗的影响.更多还原

【Abstract】 In this paper,we investigate the entanglement dynamics of two entangled two-level atoms interacting with a single_mode field in a dissipative cavity. The results show that the evolution properties of the entanglement degree of two entangled atoms depend on the initial atomic entanglement degree and form,the average photon number of the cavity field,and the cavity leakage rate. When the atoms are initially in a particular entangled state,the degree of entanglement can be amplified and not influenced by the dissipation of the cavity field.更多还原
