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…

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…

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…

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…
