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.

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.
