摘要
We derive an integral convex combination of product states for a range of separable Werner states. 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.
