<Harald Weinfurter> coauthored the preparation and observation of three-<photon> <GHZ states>. The experiment combined two entangled <photon> pairs and selected appropriate coincidence detections, producing a conditional three-<photon> <quantum state> with <polarization> <correlations> beyond those of independent pairs. Its value was to make a genuinely multipartite <entangled state> available to direct measurement.<Observation of Three-Photon Greenberger-Horne-Zeilinger Entanglement by Dik Bouwmeester and others>[Preparation scheme and coincidence-selected GHZ-state measurements]{ref}
