Abstrakt

We analyze the class of nonlocal realistic theories that was originally considered by Leggett and tested by us in a recent experiment. We derive an incompatibility theorem that works for finite numbers of polarizer settings and that does not require the previously assumed rotational symmetry of the two-particle correlation functions. The experimentally measured case involves seven different measurement settings. Using polarization-entangled photon pairs, we exclude this broader class of nonlocal realistic models by experimentally violating a new Leggett-type inequality by 80 standard deviations. © 2007 The American Physical Society.
