From a pragmatic point of view, RB protocols thereby define benchmarks that can be used to compare different digital quantum devices.In important instances ([[Standard Randomised Benchmarking]]), the benchmark can be related to the average gate fidelity, rendering RB protocols flexible certification tools. To this end, a group structure of the gate set is made use to achieve two goals: On the one hand, this is to control the theoretical prediction of error-free sequences. | From a pragmatic point of view, RB protocols thereby define benchmarks that can be used to compare different digital quantum devices.In important instances ([[Standard Randomised Benchmarking]]), the benchmark can be related to the average gate fidelity, rendering RB protocols flexible certification tools.

RB is most prominently considered for Clifford gates and has been extended to other finite groups. Assumptions on having identical noise levels per gate have been lessened ([[Standard Randomised Benchmarking]]) and [[Randomised Benchmarking with confidence]] introduced. RB schemes have been generalized to other measures of quality, such as relative average gate fidelities ([[Interleaved Randomised Benchmarking]]), the unitarity [[Purity Benchmarking]], measures for losses [[Robust characterization of loss rates]], leakage [[Robust characterization of leakage errors]], addressibility [[ Characterization of addressability by randomized benchmarking]] or even tomographic schemes that combine data from multiple RB experiment. | RB is most prominently considered for Clifford gates and has been extended to other finite groups.
