摘要 提出一种利用阶梯型三能级原子与两个双模腔谐振相互作用制备四光子GHZ态的方案。在该方案中,量子信息编码在腔场的Fock态中。通过求解薛定谔方程,得到相互作用系统的量子态。原子通过两个腔后被测量时,场能崩塌到所需要的GHZ态。结果表明该方案简单且实验上可行。 A scheme is presented for generating four-photon Greenberger-Horne-Zeilinger (GHZ) states with resonant interaction between a cascade type three-level atom and two bimodal cavities. In the proposed protocol, the quantum information is encoded on Fock states of the cavity fields. SchrSdinger equation of the system is solved and quantum states of interaction system are obtained. The detection of atom can collapse cavity to the desired GHZ state. It is shown that the scheme is simple and the experimental implementation is feasible
