    "abstract": "We have experimentally tested the non local properties of the states\ngenerated by a high brilliance source of entanglement which virtually allows\nthe direct measurement of the full set of photon pairs created by the basic QED\nprocess implied by the parametric quantum scattering. Standard Bell\nmeasurements and Bell\u0027s inequality violation test have been realized over the\nentire cone of emission of the degenerate pairs. By the same source we have\nverified the Hardy\u0027s ladder theory up to the 20th step and the contradiction\nbetween the standard quantum theory and the local realism has been tested for\n41% of entangled pairs.
