Résumé

High-dimensional quantum systems form a rapidly developing research field that covers both theoretical and experimental aspects of quantum communication and, more generally, quantum information theory. These systems provide various advantages over their low-dimensional counterparts in terms of, for example, noise resilience and information carrying capacity. In order to reach such benefits, one needs to possess a system that is not effectively low-dimensional. In this theory talk, I will introduce the concept of genuine high-dimensionality for a range of quantum devices, and discuss how this leads to experimentally testable criteria, that can rule out central low-dimensional simulation protocols in a semi-device independent manner.
