Bell inequalities: many questions, a few answers
Previous problem: Individual measurement strategies on geometrically uniform states
Next problem: Bell inequalities and operator algebras
The title was taken from a recent paper by Nicolas Gisin  where many open questions concerning Bell inequalities are presented. They are organized in three categories: fundamental, linked to experiments, and exploring nonlocality as a resource.
The fundamental question 3 corresponds to Problem number 19 on this site, the fundamental question number 14 is related to Problem number 1, but most of the open questions were not listed on this page up to now.
