摘要

The fine-grained uncertainty relation can be used to discriminate among classical, quantum, and superquantumncorrelations based on their strength of nonlocality, as has been shown for bipartite and tripartite systems withnunbiased measurement settings. Here we consider the situations when two and three parties choose settings withnbias for playing certain nonlocal games. We show analytically that while the fine-grained uncertainty principlenis still able to distinguish classical, quantum, and superquantum correlations for biased settings corresponding toncertain ranges of the biasing parameters, the above-mentioned discrimination is not manifested for all biasing.
