    "abstract": "An experiment is proposed that permits the observation of the reduced de\nBroglie wavelengths of two and four-photon wave packets using present\ntechnology. It is suggested to use a Mach-Zehnder setup and feed both input\nports with light generated by a single non-degenerate down-conversion source.\nThe strong quantum correlations of the light in conjunction with\nboson-enhancement at the input beam splitter allow to detect a two- and\nfourfold decrease in the observed de Broglie wavelength with perfect\nvisibility. This allows a reduction of the observed de Broglie wavelength below\nthe wavelength of the source.",
