A plot of lower bounds \({{\mathcal{F}}}_{L}^{* }\) on the minimum quantum fidelity \({{\mathcal{F}}}_{L}^{* }\le {{\mathcal{F}}}^{* }\) from the level L = 3 of NPA hierarchy between the actual state and the optimal self-testing state against the observed value Cα,α(p) of the symmetrically (α = β) tilted CHSH functional (15) for tilting parameters α ∈ {0.3, 0.4, 0.5, 0.6, 0.7, 0.8}.
