We have experimentally tested the nonlocal properties of the states generated by a high brilliance source of entanglement which allows the direct measurement of virtually all the photon pairs emitted over the emission cone at a certain wavelength. By this source we could verify the Hardy's ladder proof about contradiction between quantum mechanics and local realism for 41% of entangled photon pairs. The realization of an experimental test of quantum nonlocality with no need of supplementary assumptions is also extensively discussed.

Abstract
We have experimentally tested the nonlocal properties of the states generated by a high brilliance source of entanglement which allows the direct measurement of virtually all the photon pairs emitted over the emission cone at a certain wavelength. By this source we could verify the Hardy's ladder proof about contradiction between quantum mechanics and local realism for 41% of entangled photon pairs. The realization of an experimental test of quantum nonlocality with no need of supplementary assumptions is also extensively discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
