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…

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…
Quantifying multilevel coherence and multipartite correlation based on -affinity
Yan Hong, Mengjia Zhang, Limin Gao +2
Unlike standard quantum coherence, multilevel quantum coherence provides a hierarchical structure that enables a more refined characterization of quantum superposition. In this pap…
Detecting -nonstretchability via a class of informationally complete symmetric measurements
Yan Hong, Mengjia Zhang, Limin Gao +2
Characterizing multipartite entanglement is a fundamental problem in quantum information theory. The concept of -stretchability provides a framework for characterizing the struc…

Yan Hong, Yabin Xing, Limin Gao +2
The detection of multipartite entanglement in multipartite quantum systems is a fundamental and key issue in quantum information theory. In this paper, we investigate -nonsepara…
Efficient detection for quantum states containing fewer than unentangled particles in multipartite quantum systems
Yabin Xing, Yan Hong, Limin Gao +2
In this paper, we mainly investigate the detection of quantum states containing fewer than unentangled particles in multipartite quantum systems. Based on calculations about op…
Monogamy of Entanglement Measures Based on Fidelity in Multiqubit Systems
Limin Gao, Fengli Yan, Ting Gao
We show exactly that the th power of Bures measure of entanglement and geometric measure of entanglement, as special case of entanglement measures based on fidelity, obey a clas…
Monogamy of Logarithmic Negativity and Logarithmic Convex-Roof Extended Negativity
Li-Min Gao, Feng-Li Yan, Ting Gao
One of the fundamental traits of quantum entanglement is the restricted shareability among multipartite quantum systems, namely monogamy of entanglement, while it is well known tha…
Monogamy inequality in terms of entanglement measures based on distance for pure multiqubit states
Limin Gao, Fengli Yan, Ting Gao
Using very general arguments, we prove that any entanglement measures based on distance must be maximal on pure states. Furthermore, we show that Bures measure of entanglement and…

Limin Gao, Fengli Yan, Ting Gao
We investigate the tight monogamy and polygamy relations of multiparty entanglement for arbitrary quantum states. By using the power of the bipartite measure of entanglement, we es…
Tighter monogamy relations of multiqubit entanglement in terms of Rényi- entanglement
Limin Gao, Fengli Yan, Ting Gao
We present a class of tight monogamy relations in terms of Rényi- entanglement, which are tighter than the monogamy relations of multiqubit entanglement just based on the power…
