    "abstract": "We give explicit expressions for entanglement measures of Werner states in\narbitrary dimensions in terms of concurrence and tangle. We show that an\noptimal ensemble decomposition for a joint density matrix of a Werner state can\nachieve the minimum average concurrence and tangle simultaneously. Furthermore,\nthe same decomposition also attains entanglement of formation for Werner\nstates.",
