摘要通过阶梯型三能级原子与双模腔大失谐作用,提出制备四光子Greenberger-Horne-Zeilinger(GHZ)态的方案。光子作为量子信息载体,通过对原子的测量得到所需要的量子态。该方案具有实验可行性。 A scheme is presented for generating four-photon Greenberger-Horne-Zeilinger （GHZ） state with a large detuned interaction between ladder-type three-level atom and two bimodal cavities. The quantum information is encoded on the photons. The detection of atom collapses the cavity to the disired state. Our scheme is feasible in experiments.
