From: Bright-light detector control emulates the local bounds of Bell-type inequalities
Local bounds for recalibrated inequality \(S'\) [Eq. (3)], improved faking model [Eq. (6)], and perfect faking model. The quantum mechanical bound \(2\sqrt{2}\) is also shown. The improved faking model achieves this bound at \(\eta \approx 0.6678\) and the perfect model at \(\eta = 2 (\sqrt{2}-1)\). The perfect model can fully emulate Eq. (3) for efficiency range \(2/3 \le \eta \le 1\).
