Struct MeasurementErrorMitigation 

pub struct MeasurementErrorMitigation { /* private fields */ }

Measurement error mitigation using calibration matrices

Corrects readout errors by inverting the noise transfer matrix measured through calibration circuits.

Implementations

impl MeasurementErrorMitigation

pub fn new(n_qubits: usize) -> Self

Create a new measurement error mitigation instance

Arguments

• n_qubits - Number of qubits

pub fn set_calibration_matrix(&mut self, matrix: Array2<f64>) -> Result<()>

Set the calibration matrix from measurements

The calibration matrix M[i][j] represents the probability of measuring bitstring i when bitstring j was prepared.

pub fn apply( &mut self, noisy_counts: &HashMap<String, usize>, ) -> Result<HashMap<String, f64>>

Apply measurement error mitigation to noisy counts

Arguments

• noisy_counts - Raw measurement counts from the quantum circuit

Returns

Mitigated counts (may contain negative values due to inversion)

pub fn from_error_rates( n_qubits: usize, readout_error_0: f64, readout_error_1: f64, ) -> Result<Self>

Generate calibration matrix from error rates

Arguments

• readout_error_0 - Probability of measuring 1 when prepared in |0⟩
• readout_error_1 - Probability of measuring 0 when prepared in |1⟩
