Summation and product forms of uncertainty relations based on metric-adjusted skew information

Cong Xu, Qing-Hua Zhang, Shao-Ming Fei

Uncertainty principle is one of the most essential features in quantum mechanics and plays profound roles in quantum information processing. We establish tighter summation form unc…

Tighter sum uncertainty relations via $(α, β, γ)$ weighted Wigner-Yanase-Dyson skew information

Cong Xu, Zhaoqi Wu, Shao-Ming Fei

We establish tighter uncertainty relations for arbitrary finite observables via $(α, β, γ)$ weighted Wigner-Yanase-Dyson ( $(α, β, γ)$ WWYD) skew information. The results are also applic…
