Quantum computers have the potential to outperform classical computers in a variety of tasks ranging from combinatorial optimization to machine learning to intrinsically evading the sign problem. However, current intermediate-scale quantum devices still suffer from a considerable level of noise. In this talk, I will present a novel bit-flip correction method to mitigate measurement errors on quantum computers, which can be applied to any operator, any number of qubits, and any realistic bit-flip probability. I will demonstrate the experimental realization of the method on IBM quantum hardware, which reduces the final measurement error by up to one order of magnitude. This talk is based on 2007.03663.
