Classically Realizable Incompatibility
Songyi Liu, Yongjun Wang, Baoshan Wang +2
Incompatibility constitutes a fundamental aspect of quantum mechanics. However, not every quantum observable non-classical property arises from incompatibility, nor can all quantum…
Hardy's Paradox for Yu-Oh Set Constructed by Logically Contextual Quantum States
Chang He, Yongjun Wang, Baoshan Wang +2
Quantum contextuality is a fundamental nonclassical property of quantum systems, regarded as a key resource that demonstrates the computational and informational advantages of quan…
A Logical Formalism of Hardy-type Paradox
Songyi Liu, Yongjun Wang, Baoshan Wang +2
Hardy-type paradoxes provide elegant, inequality-free proofs of quantum contextuality. We introduce a unified logical formalism for these paradoxes, termed logical Hardy-type parad…
Event-based quantum contextuality theory
Songyi Liu, Yongjun Wang, Baoshan Wang +1
Fully revealing the mathmatical structure of quantum contextuality is a significant task, while some known contextuality theories are only applicable for rank-1 projectors. That is…
