Vous êtes cordialement invité(e)s d'assister à la prochaine séance du séminaire Métascience (Projet ANR Métascience) le mardi 17 decembre 2013 à 16h30 à l'IHPST.
Martin Schüle intervient sur "The Kocher-Specker Theorem: A Case for the Emergence of Space-Time?"
"In quantum physics, events can exhibit long-range correlations although there is no direct contact between them and no common cause. These so-called nonlocal correlations between space-like separated events are a central issue in quantum information science and the foundational and philosophical debate in quantum physics.
Bell's analysis of the situation led to a no-go theorem which says that it is not possible to introduce additional variables, with certain intuitive properties, that would explain the correlations. After discussing certain conceptual difficulties with Bell's theorem, I will discuss another no-go theorem by Kochen and Specker. I will claim that the Kocher-Specker theorem is more fundamental and will allow for a Bell-type argument involving time-like separated events instead of space-like separated ones. This might provide some evidence that the structure of space-time is an emerging phenomenon in nature."
