Experimental test of the violation of local realism in quantum mechanics without Bell inequalities
Open accessAbstract
We report the results of an experiment in which postselected polarization-entangled photons were used to test the recent nonlocality proof by L. Hardy [Phys. Rev. Lett. 71, 1665 (1993)]. The particular source of entangled photons used in the experiment has the advantage that it is very easy to prepare a pair of photons in a state with any degree of entanglement. Hardy's theorem, which only works for nonmaximally entangled states, was tested for a range of states.

All tests have found that, modulo some physically reasonable assumptions, nature does indeed violate local realism in accordance with quantum mechanics.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
