Robust Extraction of Tomographic Information via Randomized Benchmarking

Quantum processing tomography typically reconstructs an unknown quantum dynamical operation by measuring its effects on known states of a quantum device. Taking a different approach of comparing the operation of interest to a set of finite and easily implementable reference operations, a new method can reconstruct any quantum operation reliably.
