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.

Geometric Global Quantum Discord of Arbitrarily Two-qubit States

Abstract

We study the geometric global quantum discord (GGQD) of two-qubit systems. We give an approach for deriving analytical formulae of GGQD for arbitrary two-qubit states. Detailed examples are presented.
