Uncertainty of quantum channels via modified generalized variance and modified generalized Wigner-Yanase-Dyson skew information

Cong Xu, Zhaoqi Wu, Shao-Ming Fei

Uncertainty relation is a fundamental issue in quantum mechanics and quantum information theory. By using modified generalized variance (MGV), and modified generalized Wigner-Yanas…

Sum uncertainty relations based on $(α, β, γ)$ weighted Wigner-Yanase-Dyson skew information

Cong Xu, Zhaoqi Wu, Shao-Ming Fei

We introduce ( $α, β, γ$ ) weighted Wigner-Yanase-Dyson (( $α, β, γ$ ) WWYD) skew information and ( $α, β, γ$ ) modified weighted Wigner-Yanase-Dyson (( $α, β, γ$ ) MWWYD) skew information. We exp…

Skew information-based coherence generating power of quantum channels

Zhaoqi Wu, Lin Zhang, Shao-Ming Fei +1

We study the ability of a quantum channel to generate quantum coherence when it applies to incoherent states. We define the measure of coherence generating power (CGP) for a generi…
