Abstract:
Bell nonlocality and EPR steering are both important quantum features and quantum resources with wide applications in many quantum information processing tasks. We investigate the Bell nonlocality and steering in the framework of generalized probabilistic theories. We formulate the characterizations of Bell nonlocality and steering in this more general framework and present new insight into the essence of Bell nonlocality and steering.
