Implementing Averaged Circuit Eigenvalue Sampling with Pauli Twirling

ORAL

Abstract

We present progress towards implementing averaged circuit eigenvalue sampling (ACES) using coupled transmon qubits. ACES is a protocol for simultaneously estimating individual Pauli error rates for all gates in a given gate set using a collection of circuits [1]. We experimentally investigate the ACES protocol for measuring gate error rates and the effects of gate-specific Pauli twirling on the accuracy of the estimation procedure. We also extend the protocol to simultaneously estimate state-preparation and measurement (SPAM) errors and investigate the benefits of Pauli twirling the final measurements for accurate estimation of all errors.
