Generation of a multi-photon Greenberger–Horne–Zeilinger state with linear optical elements and photon detectors

We present a scheme to generate a multi-photon Greenberger-Horne-Zeilinger (GHZ) state by using single-photon sources, linear optical elements and photon detectors. Such a maximum entanglement has wide applications in the demonstration of quantum nonlocality and quantum information processing.
