Aspect's experiment was the first quantum mechanics experiment to demonstrate the violation of Bell's inequalities with photons using distant detectors. Its 1982 result allowed for further validation of the quantum entanglement and locality principles.
Research [ edit] Aspect's experiments, following the first experiment of Stuart Freedman and John Clauser in 1972, were considered to provide further support to the thesis that Bell's inequalities are violated in its CHSH version, in particular by closing a form of the locality loophole.
Bell test. A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein 's concept of local realism.
21 mag 2024 · Quick Reference. An experiment conducted by the French physicist Alain Aspect (1947– ) and his colleagues in the early 1980s to test Bell's inequality (see Bell's theorem). The experiment involves producing pairs of photons from a source of excited calcium ions. The photons have different wavelengths and filters are used to ensure ...
4 ott 2022 · The experiment helped pave the way for what Aspect has called the "second quantum revolution", which has led to a range of new technologies including quantum computing, encryption and more.
21 dic 2022 · Alain Aspect’s three experiments on Bell’s theorem, published in the early 1980s, were a turning point in the history of the research on the foundations of quantum mechanics not only because they corroborated entanglement as the distinctive quantum signature but also because these experiments brought wider recognition to this ...
That third experiment was done with Jean Dalibard, another brilliant master’s student who applied to join Aspect’s experiment for his military service. In a private communication, Aspect told me that it was at the heart of Einstein’s reasoning to consider such space-like separated measurements, and that he does not believe he would have received the Nobel Prize without this third ...
