Linear optical protocol for preparation of N-photon Greenberger–Horne–Zeilinger state with conventional photon detectors

Yan Xia, Jie Song, and He-Shan Song
We propose a linear optical protocol to generate GreenbergerHorneZeilinger (GHZ) state of N distant photons with the certain success probability. The proposed setup involves simple linear optical elements, N pairs of the two-photon polarization entangled states, and the conventional photon detectors ... [Appl. Phys. Lett. 92, 021127 (2008)] published Fri Jan 18, 2008.
