Optimal Universal Uncertainty Relations
Tao Li, Yunlong Xiao, Teng Ma +4
We study universal uncertainty relations and present a method called joint probability distribution diagram to improve the majorization bounds constructed independently in [Phys. R…
Mutually exclusive uncertainty relations
Yunlong Xiao, Naihuan Jing
The uncertainty principle is one of the characteristic properties of quantum theory based on incompatibility. Apart from the incompatible relation of quantum states, mutually exclu…
Near-Optimal Variance-Based Uncertainty Relations
Yunlong Xiao, Naihuan Jing, Bing Yu +2
Learning physical properties of a quantum system is essential for the developments of quantum technologies. However, Heisenberg's uncertainty principle constrains the potential kno…
Enhanced Information Exclusion Relations
Yunlong Xiao, Naihuan Jing, Xianqing Li-Jost
In Hall's reformulation of the uncertainty principle, the entropic uncertainty relation occupies a core position and provides the first nontrivial bound for the information exclusi…
Strong entropic uncertainty relations for multiple measurements
Yunlong Xiao, Naihuan Jing, Shao-Ming Fei +4
In this paper, we study entropic uncertainty relations on a finite-dimensional Hilbert space and provide several tighter bounds for multi-measurements, with some of them also valid…
Improved Uncertainty Relation in the Presence of Quantum Memory
Yunlong Xiao, Naihuan Jing, Shao-Ming Fei +1
In Coles-Piani's recent remarkable version of the entropic uncertainty principle, the entropic sum is controlled by the first and second maximum overlaps between the two projective…
Weighted Uncertainty Relations
Yunlong Xiao, Naihuan Jing, Xianqing Li-Jost +1
Recently, Maccone and Pati have given two stronger uncertainty relations based on the sum of variances and one of them is nontrivial when the quantum state is not an eigenstate of…
Uniform Entanglement Frames
Yunlong Xiao, Naihuan Jing, Xianqing Li-Jost +1
We present several criteria for genuine multipartite entanglement from universal uncertainty relations based on majorization theory. Under non-negative Schur-concave functions, the…
Geometric Global Quantum Discord of Two-qubit States
Yunlong Xiao, Tao Li, Shao-Ming Fei +3
We consider the geometric global quantum discord (GGQD) of two-qubit systems. By analyzing the symmetry of geometric global quantum discord we give an approach for deriving analyti…
