Welcome
Rendez-vous à 10h45 si vous souhaitez partager une tasse de café ou de thé avec nous ! L’atelier commence à 11 heures.
More than a decade ago I introduced a way to discuss the past of a quantum particle according to the trace it leaves. I also designed an experiment in which photons « told » us where they have been. Adding a Dove prism inside the inner interferometer causes photons to lie about their past. I will review the controversies triggered by these experiments and describe designs of devices which might have practical applications.
