Struct CalibrationMatrix 

pub struct CalibrationMatrix { /* private fields */ }

Calibration matrix for measurement error mitigation.

Implementations

impl CalibrationMatrix

pub fn from_confusion_matrix(matrix: &[&[f64]]) -> Result<Self, MitigationError>

Create from a confusion matrix.

Arguments

• matrix - 2D array where M[i][j] = P(measure i | prepared j)

pub fn identity(num_qubits: usize) -> Self

pub fn apply_inverse(&self, probs: &[f64]) -> Result<Vec<f64>, MitigationError>

Apply the inverse calibration matrix to a probability vector.

pub fn num_states(&self) -> usize

Get the number of states (2^n).

pub fn num_qubits(&self) -> usize

Get the number of qubits.
