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 weighted Wigner-Yanase-Dyson skew information
Cong Xu, Zhaoqi Wu, Shao-Ming Fei
We introduce () weighted Wigner-Yanase-Dyson (() WWYD) skew information and () modified weighted Wigner-Yanase-Dyson (() 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…
Remarks on the Sequential Products
Liu Weihua, Wu Zhaoqi, Wu Junde
In this paper, we show that those sequential products which were proposed by Liu and Shen and Wu in [J. Phys. A: Math. Theor. {\bf 42}, 185206 (2009), J. Phys. A: Math. Theor. {\bf…
