We discuss the problem of separating consistently the total correlations in a bipartite quantum state into a quantum and a purely classical part. A measure of classical correlations is proposed and its properties are explored.

- Quantum-enhanced measurements without entanglement (2017, methodology): “Such correlations are usually referred to under the collective name of quantum discord (Henderson and Vedral, 2001; Ollivier and Zurek, 2001), see also (Adesso et al., 2016; Modi et al., 2012) for recent reviews.”
