Abstract
We give explicit expressions for entanglement measures of Werner states in arbitrary dimensions in terms of concurrence and tangle. We show that an optimal ensemble decomposition for a joint density matrix of a Werner slate can achieve the minimum average concurrence and tangle simultaneously. Furthermore, the same decomposition also altains entanglement of formation for Werner slates.
