The fidelity of controlled quantum teleportation in a noisy environment
Wen-Jing Wei, Feng-Li Yan, Ting Gao
In this work, we investigate controlled quantum teleportation in the presence of noisy channels acting on the three-qubit resource state. We employ a series of generalized noisy ch…
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…
Symmetric joint measurement as a complement to the elegant joint measurement
Ying-Qiu He, Yu-Yan Zhang, Dong Ding +2
Traditional Bell state measurement (BSM) and product basis measurements (PBM) have been integral to nearly the entire development of quantum computing. Unlike the BSM and the PBM,…
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…
Strong quantum nonlocality without entanglement in every -partition
Huaqi Zhou, Ting Gao, Fengli Yan
Orthogonal product sets that are locally irreducible in every bipartition have the strongest nonlocality while also need a large number of quantum states. In this paper, we constru…
