- class BaseGateFitter(description, backend_result, xdata, qubits, fit_fun, fit_p0, fit_bounds, circuit_names, series=None, expected_state='0')[source]¶
Bases:
qiskit.ignis.characterization.fitters.BaseFitterBase class for fitters of gate errors
See BaseFitter __init__
Methods
Add new execution results to previous execution results
Fit the curve.
Plot err data.
Attributes
- description¶
Return the fitter's purpose, e.g. 'T1'
- Return type
str
- fit_fun¶
Return the function used in the fit, e.g. BaseFitter._exp_fit_fun
- Return type
Callable
- measured_qubits¶
Return the indices of the qubits to be characterized
- Return type
List[int]
- params¶
Return the fit function parameters that were calculated by curve_fit
- Return type
List[float]
- params_err¶
Return the error of the fit function parameters
- Return type
List[float]
- series¶
Return the list of series for the data
- Return type
Optional[List[str]]
- xdata¶
Return the data points on the x-axis, the independenet parameter which is fit against
- Return type
Union[List[float],array]
- ydata¶
Return the data points on the y-axis
The data points are returning in the form of a list of dictionaries:
- ydata[i]['mean'] is a list, where item
no. j is the probability of success of qubit i for a circuit that lasts xdata[j].
- ydata[i]['std'] is a list, where ydata['std'][j] is the
standard deviation of the success of qubit i.
- Return type
