摘　　要：研究了两个原子分别放置在两光子晶体热库中的量子关联。在这个系统中,描述了discord和concurrence处在不同初态下随着失谐量δ变化关系,并比较它们的区别和联系,发现当同时结合discord和concurrence描述时,可以得出非纠缠量子关联的变化趋势。最后对所得现象进行了分析。The quantum relationship between two atoms placed in two photonic crystal environment reservoirs is stud-ied.In this system,the correlation,between the discord and concurrence changeing with the detuning δ in different initial states,is described.So are their differences and comparisons between discord and concurrence.The evolution of non-entangled quantum correlation can be obtained when the two evolutions of discord and concurrence are compared.Finally,the phenomena are analyzed and summarized.

关 键 词：量子关联 量子纠缠 DISCORD
