-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…
Witnessing nonlocality in quantum network of continuous-variable systems by generalized quasiprobability functions
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
Gaussian measurements can not be used to witness nonlocality in Gaussian states as well as the network nonlocality in networks of continuous-variable (CV) systems. Thus special non…
Multipartite correlation measures and framework for multipartite quantum resources theory
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
In recent years, it has been recognized that properties of multipartite physical systems, such as genuine multipartite entanglement, can be considered as important resources for qu…
Detecting -nonseparability and -partite Entanglement with Generalized Skew Information and Mutually Unbiased Measurements
Xiaofei Qi, Yuyang Pang, Jinchuan Hou
Multipartite quantum entanglement, as a core quantum resource, is fundamental to the advancement of quantum science and technology. In multipartite quantum systems, there are two k…
