Many people have obtained theorems that give necessary and sufficient conditions for a Banach space to be isometrically isomorphic to a Hilbert space. We pursue the analogous problem in the category of operator spaces: we give numerous conditions that characterize row and column Hilbert space. Our techniques enable the calculation of cb-distances between various operator Hilbert spaces.
