Tests of signal locality and Einstein-Bell locality for multiparticle systems
Abstract
For multiparticle systems we formulate the notions of signal locality (i.e., absence of faster-than-light signaling) and Einstein-Bell locality (or local realism) and obtain inequalities between experimental correlation functions to test them. Quantum theory obeys signal locality but violates Einstein-Bell locality by a factor ${2}^{(\mathit{n}\mathrm{\ensuremath{-}}1)/2}$ for n-particle systems.

Non-classicality of GHZ correlations can be significant even for many particles.
“Thus non-classicality of the GHZ correlations can be significant even for many particles (Mermin, 1990b;Klyshko, 1993;Roy and Singh, 1991;Żukowski 1993;Gisin and Bechmann-Pasquinucci, 1998).”

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.
