WebApr 13, 2024 · Entropy is the measure of uncertainty or randomness in a system. The more entropy, the more unpredictable the random numbers. To generate secure random numbers, you need a reliable source of... 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.
