Randomised Benchmarking: Difference between revisions

Randomized benchmarking is the certification technique which falls under the [[Fidelity Estimation]] functionality. Fidelity is a measure of the "closeness" of two quantum states. It expresses the probability that one state will pass a test to identify as the other. The randomised benchmarking protocols are used to determine the error probability per gate in a computational context and also gives an overall average fidelity for the noise in the gate. The figure of merit in these protocols is 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.
