Simulating Bell Inequality Violations in Quantum Computing

How to reproduce the quantum violation of Bell inequalities on a quantum computer or simulator. Using an open-source quantum-circuit framework (Qibo), one prepares entangled spin-1/2 (two-qubit) states, measures spin correlations along chosen directions, and evaluates CHSH- and Bell-Wigner-type inequalities to observe violation of the local-hidden-variable bound - while accounting for the statistical fluctuations and device noise present on real quantum hardware.
