Established a theoretical connection between quantumness, contextuality, and nonlocality

Provides a new framework for analyzing quantum correlations

Abstract

The Clauser-Horne-Shimony-Holt-type noncontextuality inequality and the Svetlichny inequality are derived from the Alicki-Van Ryn quantumness witness. Thus a connection between quantumness and quantum contextuality, and that between quantumness and genuine multipartite nonlocality, are established.
