bstract : In this talk, I will review Bell’s theorem, which tests the non-locality of quantum mechanics, and discuss the challenges of extending such tests to cosmological scales. I will start by setting the historical context, focusing on the mid-20th-century debate between Einstein and Bohr over the role of non-locality in the formalism of quantum mechanics. Then, I will outline the derivation of the CHSH-Bell inequalities, comparing predictions from a local hidden variable theory and quantum mechanics, and briefly review how Nobel-prized experiments have resolved this debate. Finally, I will discuss the feasibility of implementing Bell tests in a cosmological setting to tell us about the quantum nature of fluctuations in the early universe.

Le séminaire des doctorant⋅es de l’I2M et du CPT à Luminy regroupe chaque semaine les doctorant⋅es du site autour d’un exposé plus ou moins (in)formel, dans un cadre convivial. Il est évidemment ouvert aux étudiant⋅es de master et aux doctorant⋅es d’autres laboratoires.
Pour le moment, le séminaire a lieu dans la salle 500-504b du TPR2, au 5ème étage.
