Characterizing Bell Polytopes for loophole free Bell tests in multipartite scenarios — •Alexander Sauer, Nils Trautmann, and Gernot Alber — Institut für Angewandte Physik, Technische Universität Darmstadt

Loophole free violations of Bell inequalities are crucial for fundamental tests of quantum nonlocality. They are also important for future applications, such as device-independent quantum cryptography. We estimate the minimal requirements on detectors for performing a loophole free Bell test with dichotomic observables in multipartite scenarios, based on a detector model which includes detector inefficiencies and dark counts. We investigate the structure of Bell polytopes via principal component analysis and take the possible quantum correlations and the no-signaling polytope into account to find suitable Bell inequalities for such tests.
