QESEM is a characterization-based error mitigation technique that achieves unbiased estimates with substantially reduced runtime cost compared to probabilistic error cancellation while outperforming zero-noise extrapolation on utility-scale circuits.
Here, we exemplify our protocol by calibrating aRZZ (π/6) on all the two-qubit gate pairs ofibm_torino
