| Abstract: | 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. |
