MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server end of 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.

Monogamy Properties of Qubit Systems

Xue-Na Zhu and Shao-Ming Fei

Abstract

We investigate monogamy relations related to quantum entanglement for $n -$ qubit quantum systems.

General monogamy inequalities are presented to the $β$ th $(β \in (0, 2))$ power of concurrence, negativity and the convex-roof extended negativity, as well as the $β$ th $(β \in (0, \sqrt{2}))$ power of entanglement of formation. These monogamy relations are complementary to the existing ones with different regions of parameter $β$ .

In additions, new monogamy relations are also derived which include the existing ones as special cases.
