Abstract
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 to reveal non-classicality even without direct knowledge of Bell's inequalities for the given problem. An extensive set of numerical results is presented and discussed.
