Maximum nonlocality in the (3,2,2) scenario
(American Physical Society, 2016-12-27)
We identify the simplest combinations of entanglement and incompatibility giving the maximum quantum violation for each of the 46 classes of tight Bell inequalities for the (3,2,2) scenario, i.e., three parties, two ...

Experimental test of quantum correlations from Platonic graphs
(Optica Publishing Group, 2018-05-29)
Great effort has been made in the investigation of contextual correlations between compatible observables due to their both fundamental and practical importance. The graph-theoretic approach to correlate events has been ...

Experimental test of high-dimensional quantum contextuality based on contextuality concentration
(American Physical Society, 2023-06-13)
Contextuality is a distinctive feature of quantum theory and a fundamental resource for quantum computation. However, existing examples of contextuality in high-dimensional systems lack the necessary robustness required ...

Certifying sets of quantum observables with any full-rank state
(American Physical Society, 2024-04-03)
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these two properties make it possible to certify ...
