Nonlocal potential of quantum measurements — •Lucas Tendick, Hermann Kampermann, and Dagmar Bruss — Institut für TheoretischePhysik III, Heinrich-Heine-Universität Düsseldorf, D-40225Düsseldorf, Germany

The usefulness of different quantum states has been analyzed in-depth with respect to Bell nonlocality ever since the foundation of quantum information theory. Various methods to quantify the nonlocality of given quantum states have been proposed and studied in the past. However, analogous analysis with focus on the measurement side are less prevalent. We analyze the potential of given measurement operators in the context of Bell nonlocality. Specifically, we attempt to quantify how useful specific sets of quantum measurements are in terms of Bell violation, trace distance to the local polytope, the volume of nonlocality, and robustness.
