MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Entanglement Monogamy Relations of Qubit Systems

Xue-Na Zhu and Shao-Ming Fei

Abstract

We investigate the monogamy relations related to the concurrence and the entanglement of formation. General monogamy inequalities given by the $\alpha$th power of concurrence and entanglement of formation are presented for $N$-qubit states.

The monogamy relation for entanglement of assistance is also established. Based on these general monogamy relations, the residual entanglement of concurrence and entanglement of formation are studied.

Some relations among the residual entanglement, entanglement of assistance and three tangle are also presented.
