Readout-Error Mitigation#

Readout-Error Mitigation (REM) is an error mitigation technique in which inverted transition / confusion matrices are applied to the noisy measurement results. This technique may also go by other names such as “measurement error mitigation” or “readout confusion inversion”. For more discussion of the theory of REM, see the section What is the theory behind REM?.
