Recent results on Bell non-locality: quantification, concentration, quantum voids
In spite of being more than 5 decades old, Bell's theorem is still at the center of quantum foundations, also playing a crucial role in
the device-independent framework for quantum information processing. In this talk we will discuss some fresh results about Bell
non-local correlations. First we introduce a natural and geometrical way to quantify non-locality.
Based on that, we will see interesting concentration phenomena taking place in the set of Bell correlations.
Finally, we will discuss something we have called quantum voids: regions on the faces of the non-signalling set
(those compatible with special relativity) where all non-local correlations are of a post-quantum nature.
By the end, and if time permits, we will see how deep learning techniques provide a novel tool to characterize and discover new kinds
of non-local correlations.
