Abstract: With the advent of quantum information theory, which concerns the general study of information processing capability of quantum systems and ushers a new vista full of challenging mathematical problems and marvelous physical potentialities, quantum correlations are playing an increasingly instrumental and significant role in the description and exploitation of nature. In this talk, we present an overview of some quantitative and informational aspects of quantum correlations. We focus on two prominent and widely studied notions of quantum correlations: discord and entanglement. In particular, we identify entanglement as the minimal shadow of discord over extended systems in terms of state dilations.
