Unification of non-classicality measures in interferometry (Physical Review A 97, 1, 012331)

Figure 1There has being a growing interesting in the various features of quantum mechanics that are distinctly non-classical, from entanglement to discord to more recent ideas of coherence. Could these various forms of non-classicality be understood in a unified operation framework? In this piece of we work, we propose a way to do this in the context of interferometry.
