Monogamy inequalities of entanglement of assistance in systems
Xue-Na Zhu, Gui Bao, Zhi-Xiang Jin +2
The monogamy relations characterize the distribution of quantum correlations among the multipartite quantum systems. We study the monogamy relations of the entanglement of assistan…

On fully entangled fraction of arbitrary quantum states
Xue-Na Zhu, Gui Bao, Ming Li +2
We study the fully entangled fraction of quantum states based on the Bloch representation of density matrices. Analytical upper bounds on the fully entangled fraction are obtained…

Classifying coherence with a finite set of witnesses
Xue-Na Zhu, Zhi-Xiang Jin, Gui Bao +1
Coherence is a fundamental resource in quantum information processing, which can be certified by a coherence witness. In order to detect all the coherent states, we introduce a use…
