Questions tagged [randomised-benchmarking]

The randomized benchmarking method yields estimates of the computationally relevant errors without relying on accurate state preparation and measurement. Since it involves long sequences of randomly chosen gates, it also verifies that error behavior is stable when used in long computations. (arXiv:0707.0963)
