    "abstract": "Two experiments of four-photon interference are performed with two pairs of\nphotons from parametric down-conversion with the help of asymmetric beam\nsplitters. The first experiment is a generalization of the Hong-Ou-Mandel\ninterference effect to two pairs of photons while the second one utilizes this\neffect to demonstrate a four-photon de Broglie wavelength of $\\lambda/4$ by\nprojection measurement.",
