Struct ProbabilisticErrorCancellation 

pub struct ProbabilisticErrorCancellation { /* private fields */ }

Probabilistic Error Cancellation for error mitigation.

Decomposes noisy gates into ideal operations using quasi-probability sampling.

Implementations

impl ProbabilisticErrorCancellation

pub fn new() -> Self

Create a new PEC mitigator.

pub fn with_num_samples(self, samples: usize) -> Self

Set the number of Monte Carlo samples.

pub fn add_representation( self, gate_name: &str, representation: QuasiProbabilityRepresentation, ) -> Self

Add a quasi-probability representation for a gate.

pub fn gamma(&self) -> f64

Calculate the sampling overhead (gamma factor).

pub fn mitigate(&self, noisy_samples: &[f64]) -> Result<f64, MitigationError>

Apply PEC to get mitigated expectation value.
