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…
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…
Strong quantum nonlocality without entanglement in -partite system with even
Huaqi Zhou, Ting Gao, Fengli Yan
In multipartite systems, great progress has been made recently on the study of strong quantum nonlocality without entanglement. However, the existence of orthogonal product sets wi…
Orthogonal product sets with strong quantum nonlocality on plane structure
Huaqi Zhou, Ting Gao, Fengli Yan
In this paper, we consider the orthogonal product set (OPS) with strong quantum nonlocality. Based on the decomposition of plane geometry, we present a sufficient condition for the…
Optimal convex approximations of quantum states based on fidelity
Huaqi Zhou, Ting Gao, Fengli Yan
We investigate the problem of optimally approximating a desired state by the convex mixing of a set of available states. The problem is recasted as finding the optimal state with t…
Entanglement resource theory of quantum channel
Huaqi Zhou, Ting Gao, Fengli Yan
Quantum channels can represent dynamic resources, which are indispensable elements in many physical scenarios. To describe certain facets of nonclassicality of the channels, it is…
Noise effects and perfect controlled remote state preparation
Yuan-hua Li, Zisheng Wang, Hua-qing Zhou +1
We investigate all possible noise environments for controlled remote state preparation. We find that the optimal efficiency is not only dependent on the isolate decay rate but also…
