qiskit.algorithms.AmplitudeEstimation.compute_confidence_interval

static AmplitudeEstimation.compute_confidence_interval(result, alpha=0.05, kind='likelihood_ratio')

Compute the (1 - alpha) confidence interval.

Parameters

• result (AmplitudeEstimationResult) – An amplitude estimation result for which to compute the confidence interval.

• alpha (float) – Confidence level: compute the (1 - alpha) confidence interval.

• kind (str) – The method to compute the confidence interval, can be ‘fisher’, ‘observed_fisher’ or ‘likelihood_ratio’ (default)

Return type

Tuple[float, float]

Returns

The (1 - alpha) confidence interval of the specified kind.

Raises

• AquaError – If ‘mle’ is not in self._ret.keys() (i.e. run was not called yet).

• NotImplementedError – If the confidence interval method kind is not implemented.
