We review a recently developed theoretical approach to the experimental detection and quantification of bipartite quantum correlations (QCs) between a qubit and a d-dimensional system. Specifically, introducing a properly designed measure Q, the presented scheme allows us to quantify general QCs for arbitrary states of 2 circle times d systems without the need to fully reconstruct them by tomographic techniques. We take in exam the specifics of the required experimental architecture in nuclear magnetic resonance (NMR) and optical settings. Finally we extend this approach to models of open system dynamics and discuss possible advantages and limitations in such a context.
