  Topological quantum computing with non-abelian anyons in a network of
one-dimensional chains relies on braiding operations. In real devices, a noisy
environment may compromise these braiding operations. In order to assess the
failure acquired during braiding with noisy parameters, I define three quality
measures. To keep the results as general as possible, I study these quality
measures in a model with minimal assumptions that still allows for different
kinds of noise.
