TensoredMeasFitter.readout_fidelity(cal_index=0, label_list=None)

Based on the results, output the readout fidelity, which is the average of the diagonal entries in the calibration matrices.

Paramètres

• cal_index (integer) – readout fidelity for this index in _cal_matrices

• label_list (list) – Returns the average fidelity over of the groups f states. In the form of a list of lists of states. If None, then each state used in the construction of the calibration matrices forms a group of size 1

QiskitError – If the calibration matrix has not been set for the object.

Additional Information:

The on-diagonal elements of the calibration matrices are the probabilities of measuring state “x” given preparation of state “x”.
