The logical structure of contextuality and nonclassicality
Songyi Liu, Yongjun Wang, Baoshan Wang +2
Quantum contextuality represents a fundamental form of nonclassicality in quantum mechanics. To provide a more complete characterization of nonclassical properties in quantum syste…

Determining Strong Contextuality on rank-one Projectors
Jiawei Nie, Yongjun Wang, Songyi Liu
The strength of quantum contextuality is closely related to quantum computation power. Yu-Oh set is the minimal quantum system with state-independent contextuality(SIC). However, i…

Graph structure of quantum mechanics
Songyi Liu, Yongjun Wang, Baoshan Wang +2
The quantum mechanics is proved to admit no hidden-variable in 1960s, which means the quantum systems are contextual. Revealing the mathematical structure of quantum mechanics is a…
