    "abstract": "We address the problem of discriminating with minimal error probability two\ngiven quantum operations. We show that the use of entangled input states\ngenerally improves the discrimination. For Pauli channels we provide a complete\ncomparison of the optimal strategies where either entangled or unentangled\ninput states are used.",
