Struct ZeroNoiseExtrapolation 

pub struct ZeroNoiseExtrapolation { /* private fields */ }

Zero-Noise Extrapolation for error mitigation

ZNE runs the same circuit at different noise levels and extrapolates the result to the zero-noise limit.

Implementations

impl ZeroNoiseExtrapolation

pub fn new(method: ExtrapolationMethod) -> Self

Create a new ZNE instance with default scale factors

pub fn with_scale_factors( method: ExtrapolationMethod, scale_factors: Vec<f64>, ) -> Result<Self>

Create ZNE with custom scale factors

pub fn apply(&self, noisy_values: &[f64], noise_scales: &[f64]) -> Result<f64>

Apply ZNE to a set of noisy expectation values

Arguments

• noisy_values - Expectation values at different noise scales
• noise_scales - Corresponding noise scale factors

pub fn scale_factors(&self) -> &[f64]

Get the scale factors
