Measurement Mitigation Utils (
The user-facing API stability of this module is not guaranteed except for
its use with the
QuantumInstance (i.e. using the
TensoredMeasFitter classes as values for the
meas_error_mitigation_cls). The rest of this module should be treated as
an internal private API that can not be relied upon.
The measurement calibration is used to mitigate measurement errors.
The main idea is to prepare all \(2^n\) basis input states and compute
the probability of measuring counts in the other basis states.
From these calibrations, it is possible to correct the average results
of another experiment of interest. These tools are intended for use solely
QuantumInstance class as part of
Measurement correction fitter for a full calibration
Measurement correction fitter for a tensored calibration.
