Comparing Bell nonlocality and Einstein–Podolsky–Rosen steering based on the chained inequalities

Abstract A family of steering inequalities are constructed from the chained Bell inequalities in a systematic manner. Then, with the Werner state, the Einstein–Podolsky–Rosen steering is compared with the Bell nonlocality through the comparison between the steering threshold value and the nonlocal threshold value of the chain inequalities. In particular, the difference between them becomes larger as the number of local measurement settings increases.
