CLOPS

Parameters were set to default values from qiskit-device-benchmarking.

CHSH Bell experiment

Parameters were set to default values from qiskit-device-benchmarking.

The closer the values in the "Violation" column are to the theoretical maximum CHSH inequality of $2 \sqrt{2} \approx 2.828427$, the better the benchmark. Looks at the "largest connected component size" (LCCS)
