Quantum average correlations and complementarity relations via metric-adjusted skew information
Xiaoyu Ma, Qing-Hua Zhang, Cong Xu
We investigate quantum average correlations and complementarity relations based on metric-adjusted skew information. Several natural averaging procedures are considered, including…
Quantum average correlation based on average coherence
Xiaoyu Ma, Qing-Hua Zhang, Cong Xu
This paper studies the quantification and structural properties of quantum average correlation based on average coherence. Motivated by two mathematically equivalent approaches to…
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…
Quantifying nonclassical correlations relative to local channels
Cong Xu, Tao Li, Ruonan Ren +2
Nonclassical correlations are significant physical resources with extensive applications in quantum information processing. We introduce the modified Wigner-Yanase-Dyson skew infor…
Tightening the entropic uncertainty relations with quantum memory in a multipartite scenario
Cong Xu, Qing-Hua Zhang, Tao Li +1
The quantum uncertainty principle stands as a cornerstone and a distinctive feature of quantum mechanics, setting it apart from classical mechanics. We introduce a tripartite quant…
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…
