Lie Algebraic Uncertainty Relations
Xiaoli Hu, Naihuan Jing, Jian Zhang +1
Uncertainty relations impose fundamental constraints on quantum observables, yet optimal bounds are needed to determine their incompatibility through the minimum attainable uncerta…
Analytic Formulas for Quantum Discord of Special Families of N-Qubit States
Jianming Zhou, Xiaoli Hu, Honglian Zhang +1
Quantum discord, a key indicator of non-classical correlations in bipartite systems, has been recently extended to multipartite scenarios [Phys. Rev. Lett. 2020, 124:110401]. We pr…
A unifying separability criterion based on extended correlation tensor
Xiaofen Huang, Tinggui Zhang, Naihuan Jing
Entanglement is fundamental inasmuch because it rephrases the quest for the classical-quantum demarcation line, and it also has potentially enormous practical applications in moder…
Separability criteria based on the correlation tensor moments for arbitrary dimensional states
Xiaofen Huang, Naihuan Jing
As one of the most profound features of quantum mechanics, entanglement is a vital resource for quantum information processing. Inspired by the recent work on PT-moments and separa…
On super quantum discord for high-dimensional bipartite state
Jianming Zhou, Xiaoli Hu, Naihuan Jing
By quantifying the difference between quantum mutual information through weak measurement performed on a subsystem one is led to the notion of super quantum discord. The super vers…
Enhanced quantum channel uncertainty relations by skew information
Xiaoli Hu, Naihong Hu, Bing Yu +1
By revisiting the mathematical foundation of the uncertainty relation, skew information-based uncertainty sequences are developed for any two quantum channels. A reinforced version…
Uncertainty relations in the product form
Xiaofen Huang, Tinggui Zhang, Naihuan Jing
We study the uncertainty relation in the product form of variances and obtain some new uncertainty relations with weight, which are shown to be tighter than those derived from the…
