Abstract

We present a method to characterise qubit gates. Utilising the supermap formalism, we create a scheme for deterministic single-qubit gate analysis. Our approach introduces a new twirling process that is applied directly through fixed circuits. This method removes the requirement to average over random gates. The results enhance randomised benchmarking techniques and are suitable for experimental setups with multi-qubit control, focusing on the precise characterisation of single-qubit gates.
