Reducing the impact of time-correlated noise on zero-noise extrapolation
Zero-noise extrapolation is a quantum error mitigation technique that has typically been studied under the ideal approximation that the noise acting on a quantum device is not time-correlated. In this work, we investigate the feasibility and performance of zero-noise extrapolation in the presence of time-correlated noise. We show that, in contrast to white noise, time-correlated noise is harder to mitigate via zero-noise extrapolation because it is difficult to scale the noise level withoutdoi:10.48550/arxiv.2201.11792 fatcat:ttetzb5pvnhghbn44sn7mrdpdi
