Violation of Bell inequalities in 2 × 3 dimensional systems

Year: 2026

Type: article

Abstract: We consider the Clauser–Horne (CH) inequality for a qubit–qutrit system. We derive the necessary and sufficient conditions for the violation of the inequality as well as some simple sufficient conditions. Remarkably, we demonstrate the importance of local parameters in violation of the inequality. In other words, there are some families of mixed states violating the inequality for which the correlation part alone is useless in the CH test.
