Co mposite quantum systems can be in generic states characterised not only by entanglement but also by more general quantum correlat ions .The inter-relation between these two quantities ensures of non-locality is still not comp letely understood. 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 d iscord is one of such correlation measure that creates new challenges among the physicists and mathemat icians. New quantificat ion of quantum discord is one of the fascinating area .The analytic formu la has been introduced only two qubit X states only. So in this paper we study for the investigation of the difficu lties in finding the analytic expression of quantum discord in general two and higher dimension quantum systems.
