Experimental Test of Bell's Inequalities Using Time- Varying Analyzers
Open accessAbstract
Correlations of linear polarizations of pairs of photons have been measured with time-varying analyzers. The analyzer in each leg of the apparatus is an acousto-optical switch followed by two linear polarizers. The switches operate at incommensurate frequencies near 50 MHz. Each analyzer amounts to a polarizer which jumps between two orientations in a time short compared with the photon transit time. The results are in good agreement with quantum mechanical predictions but violate Bell's inequalities by 5 standard deviations.

In quantum physics, observables described by operators with eigenvalues ±1 can violate the CHSH inequality.
“In quantum physics, the observables are described by operators Â, Â , B, B with eigenvalues ±1, for which the CHSH inequality can be violated [32].”
From Exactly solvable 2D model for photon propagation in curved space: loss of interference and Bell inequality violation (2022) · cites this paper as [32]
The passage on the experimental setup (indexed under Abstract; page unavailable) describes four polarizer orientations and an inequality similar in form to the Clauser–Horne–Shimony–Holt inequality. The results report a violation consistent with quantum-mechanical predictions. Our copy does not describe the observables as operators with eigenvalues ±1 or establish a violation of the CHSH inequality in that specific formulation. (LLM, conf=0.85)

“The initial atomic-cascade experiments testing Bell’s inequalities (Freedman and Clauser, 1972; Aspect et al., 1982a, 1982b) falsified Bell’s inequalities as constraints on correlations of microsystems–thus a local realistic world-view was challenged.”

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.
