Our method consists of expanding the sought-after local density operators in terms of Wigner operators. For dimension d=2, our decomposition holds for the whole separable range of Werner states, while for d>2 it is valid for a subset of separable Werner states. We illustrate the general method with the explicit examples d=2 and d=3.7 pages, 1 figuresQuantum Physicstext
