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…
Impact of the Unruh effect on the estimation precision of Gaussian channel parameters
Shoukang Chang, Yawen Tang, Wei Ye +3
Gaussian quantum channels constitute a pivotal physical framework for characterizing the dynamics of Gaussian quantum states. Extensive scholarly attention has been devoted to the…
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…
Genuinely nonlocal sets without entanglement in multipartite systems
Ying-Ying Lu, Hai-Qing Cao, Hui-Juan Zuo +1
A set of multipartite orthogonal states is genuinely nonlocal if it is locally indistinguishable in every bipartition of the subsystems. If the set is locally reducible, we say it…
Strongest nonlocal sets with minimum cardinality in multipartite systems
Hong-Run Li, Hui-Juan Zuo, Fei Shi +1
Quantum nonlocality based on state discrimination describes the global property of the set of orthogonal states and has a wide range of applications in quantum cryptographic protoc…
