摘要
We propose a linear optical protocol to generate Greenberger-Horne-Zeilinger (GHZ) state under control of a number of controllers in terms of optical elements. The proposed setup involves simple linear optical elements, (N-1)-photon polarization entangled state, and conventional photon detectors. We show that the protocol can be successfully realized with a certain probability.
