    "abstract": "We propose an experiment that permits observation of the de Broglie\ntwo-photon wave packet behavior for a pair of photons, using a Mach-Zehnder\ninterferometer. It is based on the use of pulsed lasers to generate pairs of\nphotons via spontaneous parametric down-conversion and the post-selection of\nevents. It differs from previous realizations by the use of a third\ntime-correlated photon to engineer the state of the photons. The same technique\ncan give us which-path information via an ``interaction-free\u0027\u0027 experiment and\ncan be used in other experiments on the foundations of quantum mechanics\nrelated to wave-particle duality and to nonlocality.",
