Attributes
-
backend_result¶ Return the execution results
- Return type
Union[Result,List[Result]]
-
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
List[Dict]
