Preparation Scheme for Four—atom Entangled State via Cavity Decay
Zhu Cong-zhou · Journal of Anqing Teachers College · 2009
Preparation scheme for four—atomic entangled state via cavity decay is presented by interaction between A—atoms and cavity modes.When two single—photon detectors only detect two photons,which leaked out from the four cavities simultaneously respectively,four distant atoms will be created into a four—atom GHZ entangled state with a certain probability.
