    "abstract": "It has been proposed that photon-exchange effects in atom-photon interactions\ncould lead to greatly enhanced optical nonlinearities. These might have\nwidespread application (e.g. quantum information). Here we demonstrate\nexperimentally that such exchange effects can indeed enhance the probability of\nreal absorption of photon pairs. Using nonclassical pairs of photons with\nvariable time separation, we observe a maximum suppression of pair transmission\nby at least 5% with respect to the result for uncorrelated photons.",
