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…
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…
Quantifying nonclassical correlation via the generalized Wigner-Yanase skew information
Yan Hong, Xinlan Hao, Limin Gao
Nonclassical correlation is an important concept in quantum information theory, referring to a special type of correlation that exists between quantum systems, which surpasses the…
Several families of entanglement criteria for multipartite quantum systems based on generalized Wigner-Yanase skew information and variance
Yan Hong, Xinlan Hao, Limin Gao
Quantum entanglement plays a critical role in many quantum applications, but detecting entanglement, especially in multipartite or high-dimensional quantum systems, remains a chall…
