    An all-versus-nothing nonlocality for two photons, which are maximally entangled both in polarization and in path degrees of freedom was demonstrated. Since the required measurement of local operator can be implemented with linear optics, the two-photon proposal was well within the reach of current quantum optical technology. It was noted that there was only one experiment performed to test the GHZ non-locality, a kind of all-versus-nothing nonlocality.
