Uncertainty of quantum channels based on symmetrized \r{ho}-absolute variance and modified Wigner-Yanase skew information

Cong Xu, Qing-Hua Zhang, Shao-Ming Fei

We present the uncertainty relations in terms of the symmetrized \r{ho}-absolute variance, which generalizes the uncertainty relations for arbitrary operator (not necessarily Hermi…

Uncertainty relations based on the $ρ$ -absolute variance for quantum channels

Cong Xu, Wen Zhou, Qing-Hua Zhang +1

Uncertainty principle reveals the intrinsic differences between the classical and quantum worlds, which plays a significant role in quantum information theory. By using $ρ$ -absolut…
