Abstract In this talk, I’ll present a concept of nonclassicality exploring properties of contextuality and nonlocality. Quantum contextuality is one of the most intriguing properties of quantum theory and provides a notion of nonclassicality, while nonlocality is a special case of contextuality when the physical system is composed of spatially separated subsystems. Recently, certification schemes of quantum systems based on maximal violation of noncontextuality inequalities and Bell inequalities have been developed. I’ll give a broad overview of the basic mathematical concepts and then outline the main results about certification schemes based on the following articles: https://doi.org/10.22331/q-2020-08-03-302, https://doi.org/10.1103/PhysRevA.106.012431 https://doi.org/10.48550/arXiv.2212.07133.
