Detector Error Model (DEM) for Stim circuit error analysis
A DEM describes how errors in a circuit propagate to detectors and observables. This enables efficient decoding without re-simulating the full circuit.
§DEM Format
The DEM file format consists of error instructions:
error(0.01) D0 D1
error(0.02) D2 L0Each error line specifies:
- Probability of the error occurring
- Which detectors are flipped by this error (D0, D1, …)
- Which logical observables are flipped (L0, L1, …)
