Aspect, Dalibard & Roger: testing Bell with changing analyzers

What changed

Measured photon-polarization correlations with rapidly changing analyzers and observed a violation of Bell inequalities.

Scientific scope

Measured photon-polarization correlations with rapidly changing analyzers and observed a violation of Bell inequalities. Scope limitation: The 1982 experiment is a specific test with its own assumptions. It is not described as closing every loophole addressed by later experiments.

Evidence
