Wedescribe an experimental demonstration of a novel three-photon N00N stategeneration scheme using a single source of photons based onspontaneous parametric down-conversion (SPDC). The three-photon entangled state is generatedwhen a photon is subtracted from a double pair ofphotons and detected by a heralding counter. Interference fringes measuredwith an emulated three-photon detector reveal the three-photon de Brogliewavelength and exhibit visibility > 70% without background subtraction. ©2009 Optical Society of America
