Aspect's experiments, following the first experiment ofStuart Freedman andJohn Clauser in 1972, were considered to provide further support to the thesis thatBell's inequalities are violated in itsCHSH version, in particular by closing a form of thelocality loophole. However, his results were not completely conclusive since there were loopholes that allowed for alternative explanations that comply withlocal realism.[13]
For his fundamental experiments in quantum optics and atomic physics. Alain Aspect was the first to exclude subluminal communication between the measurement stations in experimental demonstrations that quantum mechanics invalidates separable hidden-variable theories and the first to demonstrate experimentally the wave–particle duality of single photons. He co-invented the technique of velocity-selective coherent population trapping, was the first to compare theHanbury Brown-Twiss correlations of fermions and bosons under the same conditions, and the first to demonstrate Anderson localization in an ultra-cold atom system. His experiments illuminate fundamental aspects of the quantum-mechanical behaviour of single photons, photon pairs and atoms.[1]
