| 摘 要： | 提出一个方案用于转移双原子纠缠态和W态.方案基于2个原子同时与一个单模腔场非共振相互作用的模型.转移过程中,原子与腔场之间不交换量子信息.腔场仅仅是被虚激发,所以方案对腔的品质因子的要求大大降低.不需要做任何测量,原子纠缠态可以直接转移给接收方的原子,成功几率为100%.

| Abstract: | A scheme is proposed for transferring two-atom entangled state and W state.It is based on the simultaneous nonresonant interaction of two atoms with a single-mode cavity field.During the transferring process,the atoms do not transfer quantum information with the cavity.The cavity is only virtually excited and thus the requirement on the quality factor of the cavity is greatly loosened.Atomic entangled state can be directly transferred to the atoms of receiver without performing any measurement.The successful probability is 100 percent. |
