We report the experimental realization and the characterization of polarization and momentum hyper-entangled two photon states, generated by a new parametric source of correlated photon pairs. By adoption of these states a successful ''all versus nothing'' test of quantum mechanics was performed. The two photon hyper-entangled states are expected to find at an increasing rate a widespread application in state engineering and quantum information. PACS: 03.67.-a, 03.67.Mn, 03.67.Hk, 42.65. Lm
