- Abstract
We introduce modified generalized Wigner–Yanase–Dyson (MGWYD) skew information and modified weighted generalized Wigner–Yanase–Dyson (MWGWYD) skew information. By revisiting state-channel interaction based on MGWYD skew information, a family of coherence measures with respect to quantum channels is proposed. Furthermore, explicit analytical expressions of these coherence measures of qubit states are derived with respect to different quantum channels. Moreover, complementarity relations based on MGWYD skew information and MWGWYD skew information are also presented. Specifically, the conservation relations are investigated, while two interpretations of them including symmetry–asymmetry complementarity and wave-particle duality have been proposed.
