Tighter monogamy and polygamy relations of quantum entanglement in multi-qubit systems
Wen-Wen Liu, Zi-Feng Yang, Shao-Ming Fei
We investigate the monogamy relations related to the concurrence, the entanglement of formation, convex-roof extended negativity, Tsallis-q entanglement and R'enyi-α entanglement,…
Uncertainty regions of observables and state-independent uncertainty relations
Lin Zhang, Shunlong Luo, Shao-Ming Fei +1
The optimal state-independent lower bounds for the sum of variances or deviations of observables are of significance for the growing number of experiments that reach the uncertaint…
Necessary conditions on effective quantum entanglement catalysts
Yu-Min Guo, Yi Shen, Li-Jun Zhao +4
Quantum catalytic transformations play important roles in the transformation of quantum entangled states under local operations and classical communications (LOCC). The key problem…
Tighter constraints of multiqubit entanglement in terms of unified entropy
Ya-Ya Ren, Zhi-Xi Wang, Shao-Ming Fei
We present classes of monogamy inequalities related to the -th () power of the entanglement measure based on the unified-() entropy, and polygamy inequalities rela…
Quantum Information Masking of Hadamard Sets
Bao-Zhi Sun, Shao-Ming Fei, Xianqing Li-Jost
We study quantum information masking of arbitrary dimensional states. Given a set of fixed reducing pure states, we study the linear combinations of them, such that they all have t…
Tighter monogamy and polygamy relations for a superposition of the generalized -class state and vacuum
Le-Min Lai, Shao-Ming Fei, Zhi-Xi Wang
Monogamy and polygamy relations characterize the distributions of entanglement in multipartite systems. We investigate the monogamy and polygamy relations with respect to any parti…
