Errors and pseudothresholds for incoherent and coherent noise posted to the arXiv


In this paper, we study the distinctive effects that incoherent and coherent errors have on an encoded qubit.  We use the effective 1-qubit process matrix at the logical level to understand the fundamental differences between these kinds of errors.  The paper can be found at https://arxiv.org/abs/1605.03604.
