Abstract

We present an asymptotically optimal generalized measurement for the joint extraction of classical information from a quantum tetrahedron for set of non-commuting observables. The optimal uncertainty in dihedral angles is shown to scale as an inverse of the surface area. However, clustering of many small tetrahedra leads to a faster convergence to a classical geometry.
