A -partite entanglement measure of -partite quantum states
Yan Hong, Xianfei Qi, Ting Gao +1
The concept of \textquotedblleft the permutationally invariant part of a density matrx\textquotedblright constitutes an important tool for entanglement characterization of multiqub…
Detection of multipartite entanglement via quantum Fisher information
Yan Hong, Xianfei Qi, Ting Gao +1
In this paper, we focus on two different kinds of multipartite correlation, -nonseparability and -partite entanglement, both of which can describe the essential characteristi…
The verification of a requirement of entanglement measures
Xianfei Qi, Ting Gao, Fengli Yan
The quantification of quantum entanglement is a central issue in quantum information theory. Recently, Gao \emph{et al}. ( \href{http://dx.doi.org/10.1103/PhysRevLett.112.180501}{P…
Strong superadditivity relations for multiqubit systems
Xianfei Qi, Ting Gao, Fengli Yan
We investigate the distributions of quantum coherence characterized by superadditivity relations in multipartite quantum systems. General superadditivity inequalities based on the…
