International Conference on Quantum Physics of Nature (QuPoN 2015) Mitschnitt einer Veranstaltung der Fakultät für Physik am Dienstag, dem 19. Mai 2015 im Großen Festsaal der Universität Wien Teil 8. Alain Aspect: "An atomic Hong-Ou-Mandel experiment" Schnitt: Daniel Winkler Abstract: Although it was discovered and demonstrated after the experimental evidence of Bell's inequalities violations, the Hong-Ou-Mandel effect is a conceptually simpler manifestation of two particle interference effects, impossible to describe in classical terms. Three decades after its demonstration with photons, we have observed it with pairs of He* atoms. This opens the path towards a Bell's inequalities test with mechanical observables of massive particles. Alain Aspect ist Professor am Forschungslaboratorium Charles Fabry des Institut d'Optique in Orsay.
