Activate genuine nonlocality from distinguishable sets in tripartite systems
Hui-Juan Zuo, Ying-Ying Lu, Shao-Ming Fei
A set of orthogonal quantum states in multipartite systems is of genuine nonlocality if it is locally indistinguishable in every bipartition. If it is locally reducible when the pa…

Unextendible and strongly uncompletable product bases
Xiao-Fan Zhen, Hui-Juan Zuo, Fei Shi +1
In 2003, DiVincenzo {\it et al}. put forward the question that whether there exists an unextendible product basis (UPB) which is an uncompletable product basis (UCPB) in every bipa…
