Genuinely entangled subspaces and strongly nonlocal unextendible biseparable bases in four-partite systems
Huaqi Zhou, Ting Gao, Fengli Yan
A set of orthogonal pure states is an unextendible biseparable basis (UBB), which means that its complementary subspace contains only genuinely entangled states. UBBs thus serve as…

Characterizing entanglement shareability and distribution in -partite systems
Hui Li, Ting Gao, Fengli Yan
Exploring the shareability and distribution of entanglement possesses fundamental significance in quantum information tasks. In this paper, we demonstrate that the square of bipart…

Strongest quantum nonlocality in -partite systems
Mengying Hu, Ting Gao, Fengli Yan
A set of orthogonal states possesses the strongest quantum nonlocality if only a trivial orthogonality-preserving positive operator-valued measure (POVM) can be performed for each…
