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…
Distribution of spin correlation strengths in multipartite systems
Bing Yu, Naihuan Jing, Xianqing Li-Jost
For a two-qubit state the isotropic strength measures the degree of isotropic spin correlation. The concept of isotropic strength is generalized to multipartite qudit systems, and…
Strong unitary uncertainty relations
Bing Yu, Naihuan Jing, Xianqing Li-Jost
In this paper we provide a new set of uncertainty principles for unitary operators using a sequence of inequalities with the help of the geometric-arithmetic mean inequality. As th…
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…
Quantum discord of X-states as optimization of one variable function
Naihuan Jing, Bing Yu
We solve the quantum discord completely as an optimization of certain one variable function for arbitrary two qubit X state. Exact solutions of the quantum discord are obtained for…
