Self-testing of an unbounded number of mutually commuting local observables
Self-testing of an unbounded number of mutually commuting local observables
Based on the optimal quantum violation of the suitable Bell's inequality, device-independent self-testing of states and observables has been reported. It is well studied that locally commuting or compatible observables cannot be used to reveal quantum nonlocality. Therefore, self-testing of commuting local observables is not possible through the Bell test. …
