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.
This paper was started last summer when Conor Smith visited the Brown Lab. In the picture, Mauricio, Conor, and Livia celebrate during Conor's farewell lunch.
