| 摘 要： | 提出一种利用原子与腔场双光子相互作用制备原子W态的方案。在此方案中,初始时将一个制备在高能级的两能级原子注入处于真空态的腔场中,其余的两能级原子制备在低能级依次注入腔场中发生双光子相互作用。由于原子与腔场之间相互作用是共振的,因此耦合强度相对较大,这将缩短所需的相互作用时间,从而降低实验中退相干的影响。

| Abstract: | A simple scheme is presented for generating n atom W states with the two-photon resonant interaction between atoms and cavity field.In the proposed protocol,it is injected a two-level atom initially prepared in the excited state through the cavity prepared in the vacuum state.The other two-level atoms prepared in the ground state are injected into cavity.Because the interaction between the atoms and cavity field is resonant,the coupling strength can be relatively strong which will shorten the corresponding interaction time and thus reduce the effect of decoherence in experiment. |
