摘要: Two experiments of four-photon interference are performed with two pairs photons from parametric downconversion the help asymmetric beam splitters. The first experiment is a generalization Hong-Ou-Mandel effect to while second one utilizes this demonstrate de Broglie wavelength λ/4 by projection measurement.
