Nonclassicality thresholds for multiqubit states: Numerical analysis
Nonclassicality thresholds for multiqubit states: Numerical analysis
States that strongly violate Bell's inequalities are required in many quantum-informational protocols as, for example, in cryptography, secret sharing, and the reduction of communication complexity. We investigate families of such states with a numerical method which allows us to reveal nonclassicality even without direct knowledge of Bell's inequalities for the …
