    "abstract": "We derive an integral convex combination of product states for a range of\nseparable Werner states. Our method consists of expanding the sought-after\nlocal density operators in terms of Wigner operators. For dimension d=2, our\ndecomposition holds for the whole separable range of Werner states, while for\nd\u003e2 it is valid for a subset of separable Werner states. We illustrate the\ngeneral method with the explicit examples d=2 and d=3.",
