Abstract
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 applicable to the(α,γ)weighted Wigner-Yanase-Dyson((α,γ)WWYD)skew information and the weighted Wigner-Yanase-Dyson(WWYD)skew information.We also present tighter lower bounds for quantum channels and unitary channels via(α,β,γ)modified weighted Wigner-Yanase-Dyson((α,β,γ)MWWYD)skew information.Detailed examples are provided to illustrate the tightness of our uncertainty relations.
