 ==Functionality Description==
-Randomized benchmarking is the certification technique which is used to find the average error rate and the average fidelity of a noisy quantum circuit. Here, the error probability per gate is determined in computational context and the overall average fidelity of the noise in the gates is calculated. The [[figure of merit]] in this case is thus the average gate fidelity and the average error rate. The computationally relevant errors are yielded in these protocols without relying on accurate quantum state preparation and measurement.
+Randomized benchmarking refers to a collection of methods that aim to reliably estimating the magnitude of an average error of a quantum gate set in a robust fashion against state preparation and measurement error. One key [[figure of merit]] here is average gate fidelity. It achieves this goal by applying sequences of feasible quantum gates of varying length, so that small errors are amplified leading to reliable estimation.
