    "abstract": "We propose and implement a novel method to produce a spatial anti-bunched\nfield with free propagating twin beams from spontaneous parametric\ndown-conversion. The method consists in changing the spatial propagation by\nmanipulating the transverse degrees of freedom through reflections of one of\nthe twin beams. Our method use reflective elements eliminating losses from\nabsorption by the objects inserted in the beams.",
