Verifying full quantum network nonlocality in arbitrary configurations by nonlinear Bell-like inequalities
Shuyuan Yang, Jinchuan Hou, Kan He +1
Full quantum network nonlocality (FQNN) describes a scenario where all sources in a network are nonlocal. Existing criteria of FQNN can only be verified in star networks by violati…
Mutually-commuting von Neumann algebra models of quantum networks and violation of Bell-type inequalities
Shuyuan Yang, Jinchuan Hou, Kan He
Employing mutually-commuting von Neumann algebras to represent the algebra of observables on quantum systems provides a framework for studying quantum information theory in systems…
-Entanglement Measure for Multipartite Systems without Convex-Roof Extensions and its Evaluation
Jie Guo, Shuyuan Yang, Jinchuan Hou +2
Multipartite entanglement underpins quantum technologies but its study is limited by the lack of universal measures, unified frameworks, and the intractability of convex-roof exten…
Violating the bilocal inequality with separable mixed states in the entanglement-swapping network
Shuyuan Yang, Kan He
It has been showed that two entangle pure states can violate the bilocal inequality in the entanglement-swapping network, vice versa. What happens for mixed states? Whether or not…
