WebApr 13, 2024 · Most device-independent protocols are based on the violation of bipartite Bell inequalities (e.g. the CHSH inequality). In our work, we show that multipartite nonlocal correlations, testified by the violation of multipartite Bell inequalities, enable the certification of more secret randomness from the outcomes of one or two parties.

I'm aware that the optimality of the quantum strategy for the CHSH game is given by Tsirelson's bound, but presentations all skip over the (admittedly much less interesting) proof of the classical strategy's optimality.
