When considering correlations shared by quantum systems composed by many parties, entangled states and separable states are often used as synonymous of quantum and classical states, respectively. A new perspective challenges such a commonly accepted view and acknowledges the existence of more-general-than-entanglement quantum correlations, represented by the so-called quantum discord. We give here a general overview on the topic and focus on a specific protocol bridging quantum discord and entanglement in optomechanical setting.
