    "abstract": "We analyze the Pauli-channel estimation with mixed nonseparable states. It\nturns out that within a specific range entanglement can serve as a nonclassical\nresource. However, this range is rather small, that is entanglement is not very\nrobust for this application. We further show that Werner states yield the best\nresult of all Bell diagonal states with the same amount of entanglement.",
