Tighter entropic uncertainty relations in the presence of quantum memories for complete sets of mutually unbiased bases
Qing-Hua Zhang, Cong Xu, Jing-Feng Wu +1
Entropic uncertainty relations provide an information-theoretic framework for quantifying the fundamental indeterminacy inherent in quantum mechanics. We propose more stringent qua…
A note on Wigner-Yanase skew information-based uncertainty of quantum channels
Qing-Hua Zhang, Jing-Feng Wu, Shao-Ming Fei
The variance of quantum channels involving a mixed state gives a hybrid of classical and quantum uncertainties. We seek certain decomposition of variance into classical and quantum…
Between a Stone and a Hausdorff Space
Jingyi Wu, James Owen Weatherall
We consider the duality between General Relativity and the theory of Einstein algebras, in the extended setting where one permits non-Hausdorff manifolds. We show that the duality…
Parameterized Multi-observable Sum Uncertainty Relations
Jing-Feng Wu, Qing-Hua Zhang, Shao-Ming Fei
The uncertainty principle is one of the fundamental features of quantum mechanics and plays an essential role in quantum information theory. We study uncertainty relations based on…
A note on uncertainty relations of metric-adjusted skew information
Qing-Hua Zhang, Jing-Feng Wu, Xiaoyu Ma +1
The uncertainty principle is one of the fundamental features of quantum mechanics and plays a vital role in quantum information processing. We study uncertainty relations based on…
A note on uncertainty relations of arbitrary N quantum channels
Qing-Hua Zhang, Jing-Feng Wu, Shao-Ming Fei
Uncertainty principle plays a vital role in quantum physics. The Wigner-Yanase skew information characterizes the uncertainty of an observable with respect to the measured state. W…
