BernoulliDistribution

class BernoulliDistribution(p, low=0, high=1)

Bases: qiskit.aqua.components.uncertainty_models.univariate_distribution.UnivariateDistribution

The Univariate Bernoulli Distribution.

Distribution with only two values (low, high) and the corresponding probabilities represented by a single qubit.

Parameters

• p (float) – Probability

• low (float) – Low value

• high (float) – High value
