The Problem Involving the Quantification of Quantum Discord

Abstract

For the last few years, people are concentrating on studying different aspects of non-locality of quantum mechanics. Many correlation measures have been introduced and well-studied. Quantum discord is one of such correlation measures that creates new challenges among the physicists and mathematicians. New quantification of quantum discord is one of the fascinating areas. In this paper, we study for the investigation of the difficulties in finding the analytic expression of quantum discord.
