StateTomographyFitter¶

class StateTomographyFitter(result, circuits, meas_basis='Pauli')[source]¶

Maximum-Likelihood estimation state tomography fitter.

Initialize state tomography fitter with experimental data.

Parameters

result (Result) – a Qiskit Result object obtained from executing tomography circuits.
circuits (List[QuantumCircuit]) – a list of circuits or circuit names to extract count information from the result object.
meas_basis (Union[TomographyBasis, str]) – (default: ‘Pauli’) A function to return measurement operators corresponding to measurement outcomes. See Additional Information (default: ‘Pauli’)
