    "abstract": "All previous tests of local realism have studied correlations between\nsingle-particle measurements. In the present experiment, we have performed a\nBell experiment on three particles in which one of the measurements corresponds\nto a projection onto a maximally-entangled state. We show theoretically and\nexperimentally, that correlations between these entangled measurements and\nsingle-particle measurements are too strong for any local-realistic theory and\nare experimentally exploited to violate a CHSH-Bell inequality by more than 5\nstandard deviations. We refer to this possibility as \"entangled entanglement\".",
