Summary:We provide a simple prescription to extract an effective Pauli noise model from classical simulations of a noisy experimental protocol for a unitary gate. This prescription yields the closest Pauli channel approximation to the error channel associated with the gate implementation, as measured by the Frobenius distance between quantum channels. Informed by these results, we highlight some puzzles regarding the quantitative treatment of coherent errors.
