Aspect Bell Test Experiment

Measured entangled photon polarization correlations violating Bell's inequality, ruling out local hidden variables.

Core Principles & Analysis

• Alain Aspect's team at Orsay measured polarization correlations of entangled photon pairs.
• A 1982 variant switched analyzer settings while photons were in flight to close the locality loophole.
• Aspect shared the 2022 Nobel Prize in Physics with John Clauser and Anton Zeilinger.
