Sum-of-squares decompositions for a family of noncontextuality inequalities and self-testing of quantum devices
Debashis Saha, Rafael Santos, Remigiusz Augusiak
Violation of a noncontextuality inequality or the phenomenon referred to `quantum contextuality' is a fundamental feature of quantum theory. In this article, we derive a novel fami…
