Violation of these inequalities is the manifestation of nonlocality—displayed, in particular, by quantum mechanics, meaning that quantum mechanics can outperform classical physics at tasks associated with such Bell inequalities. Interestingly, however, there exist situations in which this is not the case. We associate an intriguing class of bound entangled states, constructed from unextendable product bases with a wide family of tasks, for which (i) quantum correlations do not outperform the classical ones but (ii) there exist supraquantum nonsignaling correlations that do provide an advantage.1 aAugusiak, Remigiusz1 aStasińska, Julia1 aHadley, Christopher1 aKorbicz, Jarosław, K1 aLewenstein, Maciej1 aAcín, Antonio uhttps://grupsderecerca.uab.cat/giq/publications/bell-inequalities-no-quantum-violation-and-unextendable-product-bases
