摘    要:利用光腔中二能级原子模型制备出稳定的双模纠缠态,并且运用Duan等人提出的可分离判据对双模腔场的纠缠进行了分析.研究表明:纠缠的程度与单光子泵浦光强度、合作参量、失谐频率有关,并且纠缠最大,光子数也最大.

关 键 词:腔QED  二能级  主方程  纠缠态

Abstract:The generation of entangled light via two - level atomic medium inside a two - mode optical cavity is discussed according to the entanglement criterion proposed by Duma et al. We find that, under some conditions, the two - mode cavity field exhibits stable two - mode entanglement. The degree of the entanglement is dependent on the intensity of the pump field, the detuning , and the coUective cooperativity.
Keywords:Cavity quantum electrodynamics  Two - level model  Master equation  Entanglement
