We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Characterizing Bell nonlocality and steering in generalized probabilistic theories
Zhaoqi Wu, Shao-Ming Fei, Xianqing Li-Jost and Jianhui Wang
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.
