Struct MaximumLikelihoodAE 

pub struct MaximumLikelihoodAE {
    pub schedule: Vec<usize>,
    /* private fields */
}

Maximum Likelihood Amplitude Estimation (MLAE)

Uses classical maximum likelihood estimation on measurement outcomes to achieve optimal statistical efficiency.

Fields

schedule: Vec<usize>

Number of Grover iterations to use

Implementations

pub fn with_exponential_schedule(max_power: usize, num_qubits: usize) -> Self

Create with exponential schedule: [0, 1, 2, 4, 8, …, 2^k]

pub fn estimate( &self, oracle: &dyn AmplitudeOracle, shots_per_iteration: usize, ) -> Result<(f64, f64), QuantRS2Error>
