Abstract. During the last few years people are concentrating in studying the 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.
