    "abstract": "We consider the problem of optimally discriminating two Pauli channels in the\nminimax strategy, maximizing the smallest of the probabilities of correct\nidentification of the channel. We find the optimal input state at the channel\nand show the conditions under which using entanglement strictly enhances\ndistinguishability. We finally compare the minimax strategy with the Bayesian\none.",
