Abstract
A simple experimental scheme is proposed to generate a three-photon entangled state and a genuine four-photon entangled state that has many interesting entanglement properties and possible applications in quantum information processing. These multipartite entangled states can be generated with a certain success probability. We show that even when the quantum efficiency of the detector is , the success probability can reach for -state production and for -state production. The scheme is based only on simple linear optical elements and conventional photon detectors, which greatly decrease the experimental difficulty of implementing linear optical quantum computation.
