Quantifying Multipartite Entanglement Based on unified entropy
Yan Hong, Tongtong Xu, Limin Gao
In this paper, we investigate the characterization of multipartite entanglement based on the unified -entropy framework. For bipartite quantum states, we propose an entangle…
Discrimination of genuinely nonlocal sets without entanglement in multipartite systems
Ziying Hou, Huaqi Zhou, Limin Gao
Genuine nonlocality arises when a set of multipartite orthogonal states is locally indistinguishable under any bipartition of the subsystems. The entanglement-assisted discriminati…
Tight Trade-off Between Internal, Assisted, and External Entanglement
Limin Gao, Chenxiao Wang
We derive a tight and saturable monogamy relation for three-qubit pure states that bounds the sum of concurrence and concurrence of assistance by the entanglement with an external…
Entanglement-Assisted Discrimination of Nonlocal Sets of Orthogonal States
Ziying Hou, Huaqi Zhou, Limin Gao
Entanglement-assisted discrimination of orthogonal quantum states exhibiting quantum nonlocality is a frontier topic in quantum information theory. In this paper, we investigate th…
Tighter monogamy and polygamy relations in multiparty quantum systems
Chenxiao Wang, Limin Gao
The monogamy and polygamy properties of quantum entanglement characterize fundamental constraints on the distribution of entanglement in multipartite quantum systems. In this paper…
Efficient discrimination schemes for unextendible product bases with strong quantum nonlocality
Qiqi Feng, Huaqi Zhou, Limin Gao
Entanglement is a central resource in quantum information science, and it is therefore important to design local discrimination protocols that minimize entanglement cost. In this p…
