Three-input Majority Function as the Unique Optimal Function for the Bias Amplification using Nonlocal Boxes

Ryuhei Mori

Brassard et al. [Phys. Rev. Lett. 96, 250401 (2006)] showed that shared nonlocal boxes with the CHSH probability greater than $\frac{3+\sqrt{6}}{6}$ yields trivial communication comp…
