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 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…
