Fields

num_detectors: usize

Number of detectors in the circuit

num_observables: usize

Number of logical observables

errors: Vec<DEMError>

List of error mechanisms

coordinate_shifts: Vec<Vec<f64>>

Coordinate system shifts (for visualization)

detector_coords: HashMap<usize, Vec<f64>>

Implementations

impl DetectorErrorModel

pub fn new(num_detectors: usize, num_observables: usize) -> Self

Create a new empty DEM

pub fn from_circuit(circuit: &StimCircuit) -> Result<Self>

Generate a DEM from a Stim circuit

This performs error analysis by:

1. Identifying all error mechanisms in the circuit
2. Propagating each error through to detectors/observables
3. Recording which detectors/observables are affected

pub fn to_dem_string(&self) -> String

Convert DEM to Stim DEM format string

pub fn from_dem_string(s: &str) -> Result<Self>

Parse a DEM from string

pub fn sample(&self) -> (Vec<bool>, Vec<bool>)

Sample errors according to the DEM

Returns (detector_outcomes, observable_flips) for a single sample

pub fn sample_batch(&self, num_shots: usize) -> Vec<(Vec<bool>, Vec<bool>)>

Sample multiple shots

pub fn total_error_probability(&self) -> f64

Get the total error probability

pub fn num_error_mechanisms(&self) -> usize

Get number of error mechanisms

Trait Implementations

impl Clone for DetectorErrorModel

fn clone(&self) -> DetectorErrorModel

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DetectorErrorModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result
