Alain Aspect (born 15 June 1947) is a French physicist whose experiments on entangled photons became landmarks in tests of Bell inequalities and the empirical study of quantum nonlocality.
Quantum context
Aspect's early-1980s experiments tested whether correlations between spatially separated quantum systems could be explained by local hidden-variable theories. The results supported the quantum-mechanical predictions for entangled photon pairs and helped make Bell tests a central experimental tool in quantum foundations.
His work connects directly with Physics:Quantum entanglement, Physics:Quantum nonlocality, and modern quantum information experiments, where Bell inequality violations are used to certify nonclassical correlations.
