Explicit support and gauge functions characterize the correlation sets in the (2,m,2) Bell scenario for three state spaces, yielding optimal witnesses for entanglement and beyond-quantum correlations with noise robustness thresholds.
(78) Since m = 2, we haver = min{rank A, rank B} = 2, so γAB sep (CΦ+) = 2 and pcrit = 1/2

Dualistic operational characterization of device-dependent correlation sets via convex analysis in the $(2,m,2)$ Bell scenario
