Certifying sets of quantum observables with any full-rank state
Xu, Zhen-Peng; Saha, Debashis; Bharti, Kishor; Cabello Quintero, Adán (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 ...

Maximum nonlocality in the (3,2,2) scenario
López Rosa, Sheila; Xu, Zhen-Peng; Cabello Quintero, Adán (American Physical Society, 2016-12-27)We identify the simplest combinations of entanglement and incompatibility giving the maximum quantum violation for each ...

Necessary and sufficient condition for contextuality from incompatibility
Xu, Zhen-Peng; Cabello Quintero, Adán (American Physical Society, 2019-02-12)Measurement incompatibility is the most basic resource that distinguishes quantum from classical physics. Contextuality ...
