- class TensoredMeasFitter(results, mit_pattern, substate_labels_list=None, circlabel='')¶
Deprecated: Measurement correction fitter for a tensored calibration.
Initialize a measurement calibration matrix from the results of running the circuits returned by measurement_calibration_circuits.
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_clskwarg of the
QuantumInstanceclass's constructor (as a class not an instance). Anything outside of that usage does not have the normal user-facing API stability.
0.24.0 ভার্সন থেকে ডেপ্রিকেটেড: The class
qiskit.utils.mitigation.fitters.TensoredMeasFitteris 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.
results -- the results of running the measurement calibration circuits. If this is None, the user will set calibration matrices later.
mit_pattern (List[List[int]]) -- qubits to perform the measurement correction on, divided to groups according to tensors
substate_labels_list (List[List[str]]) -- for each calibration matrix, the labels of its rows and columns. If None, the labels are ordered lexicographically
circlabel (str) -- if the qubits were labeled
ValueError -- if the mit_pattern doesn't match the substate_labels_list
Add measurement calibration data
Based on the results, output the readout fidelity, which is the average of the diagonal entries in the calibration matrices.
Return a fitter object that is a subset of the qubits in the original list.
Return a measurement filter using the cal matrices.
