We construct a family of quantum error-correcting codes with parameters nn-2kk+1q which are defined in q-dimensional quantum systemswhere q is an arbitrary prime power. These codes are optimal in the sense that the minimum distance is maximal. It is shown that codes exist for all n satisfying 2≤n≤q or q2-q+2≤n≤q2.
