Abstract
Great progress has been made recently in establishing conditions for separa bility of a particular class of Werner densities on the tensor product spac e of n d-level systems (qudits). In this brief note we complete the process of establishing necessary and sufficient conditions for separability of th ese Werner densities by proving the sufficient condition for general n and d.
