Benchmarking the development of quantum computing platforms requires accurate characterization of noise affecting gate implementations. Yet characterization protocols themselves use imperfectly implemented quantum operations. They must therefore be robust against the noise introduced by these operations. Many robust approaches rely on randomization over gate sets.

In this seminar, we will present a line of research on the theory and practical characterization of average gate-set noise. The aim is to move beyond fidelity estimates and obtain richer diagnostic information, including novel measures of crosstalk and improved predictions of circuit-level performance. We will describe general protocols and theoretical guarantees for learning linear properties of the average noise associated with a gate set, examine their implications for other characterization and mitigation methods, and discuss recent hardware-accelerated implementations on superconducting-qubit platforms.
