Earlier, I highlighted the paper by the Zeilinger's group that rules out a class of realism model via the violation of the Leggett inequality. Now comes two more papers in last week's Phys. Rev. Lett. that made further tests of such violation.
The first one is more of a refinement of their earlier work from the Zeilinger's group. This one supposedly rules out a larger class of local realism model without the assumed rotational symmetry of the earlier tests.
T. Paterek et al. "Experimental Test of Non-Local Realistic Theories Without The Rotational Symmetry Assumption", Phys. Rev. Lett. 99, 210406 (2007).
The second paper in the same issue also tests the Leggett inequality and finds a clear violation of it.
Cyril Branciard et al. " Experimental Falsification of Leggett's Nonlocal Variable Model", Phys. Rev. Lett. 99, 210407 (2007).
It is amazing that tests after tests all produce a consistent result that are in full agreement with quantum mechanics. At some point, this will become a very convincing body of evidence.
