Abstract
We introduce () weighted Wigner-Yanase-Dyson (() WWYD) skew information and () modified weighted Wigner-Yanase-Dyson (() MWWYD) skew information. We explore the sum uncertainty relations for arbitrary mutually noncommutative observables based on () WWYD skew information. A series of uncertainty inequalities are derived. We show by detailed example that our results cover and improve the previous ones based on the original Wigner-Yanase (WY) skew information. Finally, we establish new sum uncertainty relations in terms of the () MWWYD skew information for arbitrary quantum channels.
