  Quantum Ricci curvature has been introduced recently as a new, geometric
observable characterizing the curvature properties of metric spaces, without
the need for a smooth structure. Besides coordinate invariance, its key
features are scalability, computability and robustness. We demonstrate that
these properties continue to hold in the context of nonperturbative quantum
gravity, by evaluating the quantum Ricci curvature numerically in
two-dimensional Euclidean quantum gravity, defined in terms of dynamical
triangulations. Despite the well-known, highly nonclassical properties of the
underlying quantum geometry, its Ricci curvature can be matched well to that of
a five-dimensional round sphere.
