Unextendible product bases from orthogonality graphs
Fei Shi, Ge Bai, Xiande Zhang +2
Unextendible product bases (UPBs) play a key role in the study of quantum entanglement and nonlocality. A famous open question is whether there exist genuinely unextendible product…
Unextendible and uncompletable product bases in every bipartition
Fei Shi, Mao-Sheng Li, Xiande Zhang +1
Unextendible product basis is an important object in quantum information theory and features a broad spectrum of applications, ranging bound entangled states, quantum nonlocality w…
Strong quantum nonlocality and unextendibility without entanglement in -partite systems with odd
Yiyun He, Fei Shi, Xiande Zhang
A set of orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition, which shows the phenomenon of strong quantum nonlocality without entangle…
Strong quantum nonlocality for unextendible product bases in heterogeneous systems
Fei Shi, Mao-Sheng Li, Lin Chen +1
A set of multipartite orthogonal product states is strongly nonlocal if it is locally irreducible in every bipartition, which shows the phenomenon of strong quantum nonlocality wit…
Unextendible product operator basis
Mengyao Hu, Lin Chen, Fei Shi +2
Quantum nonlocality is associated with the local indistinguishability of orthogonal states. Unextendible product basis (UPB), a widely used tool in quantum information, exhibits no…
Strongly nonlocal unextendible product bases do exist
Fei Shi, Mao-Sheng Li, Mengyao Hu +4
A set of multipartite orthogonal product states is locally irreducible, if it is not possible to eliminate one or more states from the set by orthogonality-preserving local measure…
