  Famously, the violation of Bell’s inequalities, prescribed by QM, has been confirmed experimentally. Is something similar possible for the KS theorem? We should distinguish three questions: (1) Is it possible to realize the experiment proposed by KS as a motivation of their theorem?  (2) Is it possible to test the principles leading to the theorem: the Sum Rule and Product Rule, FUNC, or NC? (3) Is it possible to test the theorem itself?
