	abstract = {  We describe how randomized benchmarking can be used to reconstruct the unital
part of any trace-preserving quantum map, which in turn is sufficient for the
full characterization of any unitary evolution, or more generally, any unital
trace-preserving evolution. This approach inherits randomized benchmarking{\textquoteright}s
robustness to preparation and measurement imperfections, therefore avoiding
systematic errors caused by these imperfections. We also extend these
techniques to efficiently estimate the average fidelity of a quantum map to
unitary maps outside of the Clifford group. The unitaries we consider include
operations commonly used to achieve universal quantum computation in a
fault-tolerant setting. In addition, we rigorously bound the time and sampling
complexities of randomized benchmarking procedures.
