<br> <br><p>Quantum discord in a bipartite system can be dynamically revealed and quantified through purely local operations on one of the two subsystems. To achieve this, the local detection method harnesses the influence of initial correlations on the reduced dynamics of an interacting bipartite system. This article’s aim is to provide an accessible introduction to this method and to review recent theoretical and experimental progress.</p><br><br> <br><br><br><br> <br><p>Experimental achievements in the last decades have established the precise quantum control of individual quantum systems Wineland (2013); Haroche (2013). Furthermore, recent efforts are focussed on the assembly and monitoring of interacting quantum systems, with various applications in the context of quantum information Bloch et al. (2008); Häffner et al. (2008); Schneider et al. (2012); Blatt and Roos (2012). The efficient characterization of the underlying quantum s
