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 ...

Quantum nonlocality via local contextuality with qubit-qubit entanglement
Saha, Debashis; Cabello Quintero, Adán; Choudhary, Sujit K.; Pawłowski, Marcin (American Physical Society, 2016-04-28)Quantum nonlocality can be revealed “via local contextuality” in qudit-qudit entangled systems with d > 2 , that is, ...
