多个囚禁离子纠缠态的制备

提出了一个制备任意多个囚禁离子叠加运动相干态的方案.制备的叠加运动相干态在位相空间呈一直线分布,该方案能用来制备任意多个囚禁离子的最大纠缠GHZ态.方案中仅使用了一束驻波光,驻波光的载波频率使得离子发生跃迁,而所有离子同时所处的位置可以不限于激光的波腹而处在任意位置.这能给实验带来许多便利,同时,只要选择激光的Rabi频率足够大,相应的操作时间可以足够短.

Preparation of Entangled State for Multiple Trapped Ions

Proposes a scheme to generate a superposition of motional coherent states with ar- bitrary multiple trapped ions. The superposition of motional coherent states distributes on a line in phase space,the scheme can prepare the maximum entangled GHZstate for arbitrary multiple trapped ions. The scheme uses a single standing-wave laser pulse whose carrier frequency causethe transition of ions, each ion dose not need to be exactly positioned at the node of the standing wave but arbitrary positioned, which brings a lot of convenience to the experiment. Furthermore, as long as the Rabi frequency of laser is big enough, the corresponding operating time can be short enough.
