Averaged circuit eigenvalue sampling
Steven T. Flammia
We introduce ACES, a method for scalable noise metrology of quantum circuits that stands for Averaged Circuit Eigenvalue Sampling. It simultaneously estimates the individual error…

Pauli error estimation via Population Recovery
Steven T. Flammia, Ryan O'Donnell
Motivated by estimation of quantum noise models, we study the problem of learning a Pauli channel, or more generally the Pauli error rates of an arbitrary channel. By employing a n…
