We quantify how well matrix product states approximate exact ground states of1-D quantum spin systems as a function of the number of spins and the entropyof blocks of spins. We also investigate the convex set of local reduced densityoperators of translational invariant systems. The results give a theoreticaljustification for the high accuracy of renormalization group algorithms, andjustifies their use even in the case of critical systems.

Matrix product states represent ground states faithfully
