Abstract
An experimental scheme was proposed for preparing a polarization entangled W states from four photons emitted by parametric down-conversion. Two different configurations and a method of improving the yield by using single-photon sources were considered. It was shown that one uses only linear optical elements and photon detectors in the proposed scheme.
