Query: Observation of stronger-than-binary correlations with entangled photonic
  qutrits   We present the first experimental confirmation of the quantum-mechanical
prediction of stronger-than-binary correlations. These are correlations that
cannot be explained under the assumption that the occurrence of a particular
outcome of an $n \ge 3$-outcome measurement is due to a two-step process in
which, in the first step, some classical mechanism precludes $n-2$ of the
outcomes and, in the second step, a binary measurement generates the outcome.
Our experiment uses pairs of photonic qutrits distributed between two
laboratories, where randomly chosen three-outcome measurements are performed.
We report a violation by {9.3} standard deviations of the optimal inequality
for nonsignaling binary correlations.
