One-way quantum deficit for systems
Biao-Liang Ye, Shao-Ming Fei
We investigate one-way quantum deficit for systems. Analytical expressions of one-way quantum deficit under both von Neumann measurement and weak measurement are prese…
Sum uncertainty relations based on Wigner-Yanase skew information
Bin Chen, Shao-Ming Fei, Gui-Lu Long
We study sum uncertainty relations for arbitrary finite quantum mechanical observables. Some uncertainty inequalities are presented by using skew information introduced by Wign…
Connecting the UMEB in with partial Hadamard matrices
Yan-Ling Wang, Mao-Sheng Li, Shao-Ming Fei +1
We study the unextendible maximally entangled bases (UMEB) in and connect it with the partial Hadamard matrix. Firstly, we show that for a…
Strong entropic uncertainty relations for multiple measurements
Yunlong Xiao, Naihuan Jing, Shao-Ming Fei +4
In this paper, we study entropic uncertainty relations on a finite-dimensional Hilbert space and provide several tighter bounds for multi-measurements, with some of them also valid…
Weighted Uncertainty Relations
Yunlong Xiao, Naihuan Jing, Xianqing Li-Jost +1
Recently, Maccone and Pati have given two stronger uncertainty relations based on the sum of variances and one of them is nontrivial when the quantum state is not an eigenstate of…
One-way Quantum Deficit and Decoherence for Two-qubit States
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
We study one-way quantum deficit of two-qubit states systematically from analytical derivations. An effective approach to compute one-way quantum deficit of two-qubit state…
