CompleteMeasFitter¶

class CompleteMeasFitter(results, state_labels, qubit_list=None, circlabel='')[source]¶

Bases : object

Deprecated: Measurement correction fitter for a full calibration

Initialize a measurement calibration matrix from the results of running the circuits returned by measurement_calibration_circuits

A wrapper for the tensored fitter

Avertissement

This class is not a public API. The internals are not stable and will likely change. It is used solely for the measurement_error_mitigation_cls kwarg of the QuantumInstance class’s constructor (as a class not an instance). Anything outside of that usage does not have the normal user-facing API stability.

Obsolète depuis la version 0.24.0: The class qiskit.utils.mitigation.fitters.CompleteMeasFitter is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/qi_migration.

Paramètres

results – the results of running the measurement calibration circuits. If this is None the user will set a calibration matrix later.
state_labels (List[str]) – list of calibration state labels returned from measurement_calibration_circuits. The output matrix will obey this ordering.
qubit_list (List[int]) – List of the qubits (for reference and if the subset is needed). If None, the qubit_list will be created according to the length of state_labels[0].
circlabel (str) – if the qubits were labeled.

Methods

`add_data`	Add measurement calibration data
`readout_fidelity`	Based on the results, output the readout fidelity which is the normalized trace of the calibration matrix
`subset_fitter`	Return a fitter object that is a subset of the qubits in the original list.

Attributes

cal_matrix¶: Return cal_matrix.

filter¶: Return a measurement filter using the cal matrix.

qubit_list¶: Return list of qubits.

state_labels¶: Return state_labels.
