[GitHub](https://github.com/qiskit/qiskit/tree/stable/0.46/qiskit/algorithms/amplitude_estimators/fae.py)

Bases: [`AmplitudeEstimatorResult`](/docs/api/qiskit/0.46/qiskit.algorithms.AmplitudeEstimatorResult "qiskit.algorithms.amplitude_estimators.amplitude_estimator.AmplitudeEstimatorResult")

The result object for the Faster Amplitude Estimation algorithm.

## Attributes

### circuit\_results

Return the circuit results. Can be a statevector or counts dictionary.

### confidence\_interval

Return the confidence interval for the amplitude (95% interval by default).

### confidence\_interval\_processed

Return the post-processed confidence interval (95% interval by default).

### estimation

Return the estimation for the amplitude in $[0, 1]$.

### estimation\_processed

Return the estimation for the amplitude after the post-processing has been applied.

### num\_first\_state\_steps

Return the number of steps taken in the first step of algorithm.

### num\_oracle\_queries

Return the number of Grover oracle queries.

### num\_steps

Return the total number of steps taken in the algorithm.

### post\_processing

Return a handle to the post processing function.

### shots

Return the number of shots used. Is 1 for statevector-based simulations.

### success\_probability

Return the success probability of the algorithm.

### theta\_intervals

Return the confidence intervals for the angles in each iteration.

## Methods

### combine

`combine(result)`

Any property from the argument that exists in the receiver is updated. :param result: Argument result with properties to be set.

**Raises**

[**TypeError**](https://docs.python.org/3/library/exceptions.html#TypeError) – Argument is None
