Experimental application of the theorem
A Bell test is an experimental procedure designed to check whether the statistical correlations between quantum particles violate the inequalities derived in Bell's theorem.

Experimental verification of Bell state properties
Bell tests are physical experiments designed to verify the non-local correlations predicted by Bell states, confirming the predictions of quantum mechanics over local realism.

empirical validation of quantum entanglement
These experiments, most notably by Alain Aspect and others, provide the physical evidence that entangled particles exhibit correlations that exceed the limits of classical physics.
