  We devise a protocol in which general non-classical multipartite correlations
produce a physically relevant effect, leading to the creation of bipartite
entanglement. In particular, we show that the relative entropy of quantumness,
which measures all non-classical correlations among subsystems of a quantum
system, is equivalent to and can be operationally interpreted as the minimum
distillable entanglement generated between the system and local ancillae in our
protocol. We emphasize the key role of state mixedness in maximizing
non-classicality: Mixed entangled states can be arbitrarily more non-classical
than separable and pure entangled states.
