Characterizing nonclassical correlations of tensorizing states in a bilocal scenario

Popis výsledku v původním jazyce

In the present paper, we attempt to address the question of "can tensorizing states (rho circle times rho or rho circle times rho circle times rho') have quantum advantages? ". To answer this question, we exploit the notion of measurement-induced nonlocality (MIN) and advocate a fidelity-based nonbilocal measure to capture the nonlocal effects of tensorizing states due to locally invariant von Neumann projective measurements. We show that the properties of the fidelity-based nonbilocal measures are retrieved from that of MIN. Analytically, we evaluate the nonbilocal measure for any arbitrary pure state. The upper bounds of the nonbilocal measure based on fidelity are also obtained in terms of eigenvalues of correlation matrix. As an illustration, we have computed the nonbilocality for some popular input states.
