Randomized benchmarking

Randomized benchmarking is a technique used in quantum computing to assess the fidelity and performance of quantum operations (gates) in quantum algorithms. It provides a way to characterize the accuracy and robustness of quantum gates against errors, which is crucial for fault-tolerant quantum computation. The main idea behind randomized benchmarking is to apply a sequence of randomly chosen quantum gates, followed by a specific gate that is supposed to reverse the effects of the preceding gates.
