在原子-腔-光纤系统中制备N个腔模的W态OA北大核心CSCDCSTPCD
Generation of N-cavity field W state in atom-cavity-fiber system
提出了一个在原子-腔-光纤系统中制备最大纠缠的W态方案,要求原子与腔之间的耦合常数要比拉比频率小的多,通过暗态绝热演化方法,使原子的自发辐射和光模损耗得到有效抑制.因此一些参数的涨落对此方案的影响比较小.该方案操作比较简便,只要调节原子与腔场之间的耦合系数就能得到W态.此系统构成量子网络的一部分.
A robust scheme was proposed for generating maximally W entangled states of cavity field in atom-cavity-fiber system.The scheme requires that the coupling coefficient between cavity and atom is much smaller than Rabi frequency.The atomic spontaneous emission and fiber modes decay are suppressed efficiently via employing adiabatic evolution along dark states.So it is insensitive to the small fluctuation of some parameters.It is also convenient only by adjusti…查看全部>>
