Error Mitigation

Error mitigation involves post-processing the results of a computation to reduce the impact of errors. This is typically done by applying statistical techniques to the results of the computation, such as extrapolation or bootstrapping, to reduce the noise and errors present in the data. Extrapolation involves fitting a model to the data and using it to estimate the true value of a quantity. Bootstrapping involves resampling the data and using the resampled data to estimate the uncertainty in the measurement.
