Methods
Return the ZZ rate from the fit of the two curves
Add new execution results to previous execution results
Fit the curve.
Plot coherence data.
Plot ZZ data.
Return the characteristic time for the given qubit and series
Return the error of characteristic time for the given qubit and series
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
