      abstract     = {We develop a classical bit-flip correction method to
                      mitigate measurement errors on quantum computers. This
                      method can be applied to any operator, any number of qubits,
                      and any realistic bit-flip probability. We first demonstrate
                      the successful performance of this method by correcting the
                      noisy measurements of the ground-state energy of the
                      longitudinal Ising model. We then generalize our results to
                      arbitrary operators and test our method both numerically and
                      experimentally on IBM quantum hardware. As a result, our
                      correction method reduces the measurement error on the
                      quantum hardware by up to one order of magnitude. We finally
                      discuss how to preprocess the method and extend it to other
                      error sources beyond measurement errors. For local
                      Hamiltonians, the overhead costs are polynomial in the
                      number of qubits, even if multiqubit correlations are
                      included.},
