  I review recent works showing that information geometry is a useful framework
to characterize quantum coherence and entanglement. Quantum systems exhibit
peculiar properties which cannot be justified by classical physics, e.g.
quantum coherence and quantum correlations. Once confined to thought
experiments, they are nowadays created and manipulated by exerting an exquisite
experimental control of atoms, molecules and photons. It is important to
identify and quantify such quantum features, as they are deemed to be key
resources to achieve supraclassical performances in computation and
communication protocols. The information geometry viewpoint elucidates the
advantage provided by quantum superpositions in phase estimation. Also, it
enables to link measures of coherence and entanglement to observables, which
can be evaluated in a laboratory by a limited number of measurements.
