Editing Bell test (section)

=== Aspect et al. (1982) ===
{{main|Aspect's experiment}}
[[Alain Aspect]] and his team at Orsay, Paris, conducted three Bell tests using calcium cascade sources. The first and last used the [[Clauser and Horne's 1974 Bell test|CH74 inequality]]. The second was the first application of the [[CHSH Bell test|CHSH inequality]]. The third (and most famous) was arranged such that the choice between the two settings on each side was made during the flight of the photons (as originally suggested by [[John Stewart Bell|John Bell]]).<ref name="Aspect-1981">{{cite journal |author1=Alain Aspect |author2=Philippe Grangier |author3=Gérard Roger |year=1981 |title=Experimental Tests of Realistic Local Theories via Bell's Theorem |journal=Phys.
