Abstract

We describe an experimental demonstration of a novel three-photon NOON state generator using a single source of photons based on spontaneous parametric down-conversion (SPDC). The three-photon number-entangled state is deterministically generated by the detection of a heralding photon. Interference fringes measured with an emulated three-photon absorber reveal the three-photon de Broglie wavelength and exhibit visibility > 70% without background subtraction.
