Contextuality without nonlocality in a superconducting quantum system

Tests of the Bell-Kochen-Specker theorem aim at showing that the measurement statistics of a single qutrit are incompatible with noncontextual realism. Here, the authors use a superconducting qutrit with deterministic readouts to violate a noncontextuality inequality, ruling out several loopholes.
