Generation of multi-photon entangled states by using linear optical elements and a projective measurement

At first we present a scheme to generate the two-photon entangled state |Φ 2〉= 1 2 (|0〉|0〉|1〉|1〉+|1〉|1〉|0〉|0〉) by single-photon sources, beam splitters and single-photon detectors. Then we demonstrate the generation of multi-photon GHZ-states.
