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…
Steered quantum coherence and quantum Fisher information in spin-chain system
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
In this paper, we investigate steered quantum coherence, i.e., the norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information…
Summation and product forms of uncertainty relations based on metric-adjusted skew information
Cong Xu, Qing-Hua Zhang, Shao-Ming Fei
Uncertainty principle is one of the most essential features in quantum mechanics and plays profound roles in quantum information processing. We establish tighter summation form unc…
Tighter sum uncertainty relations via weighted Wigner-Yanase-Dyson skew information
Cong Xu, Zhaoqi Wu, Shao-Ming Fei
We establish tighter uncertainty relations for arbitrary finite observables via weighted Wigner-Yanase-Dyson (WWYD) skew information. The results are also applic…
Detection of Network and Genuine Network Quantum Steering
Zhihua Chen, Kai Wu, Shao-Ming Fei
The quantum network correlations play significant roles in long distance quantum communication,quantum cryptography and distributed quantum computing. Generally it is very difficul…
Parameterized steering criteria via correlation matrices
Qing-Hua Zhang, Lemin Lai, Shao-Ming Fei
We study the steerability for arbitrary dimensional bipartite systems based on the correlation matrices given by local special unitary groups. We present families of steering crite…
