StageInfo¶

class StageInfo(name: str, axis: str | None, factor: float, metadata: dict[str, Any])[source]¶

Bases: NamedTuple

Per-stage dry-run report.

factor is the ratio of logical circuits after this stage to circuits before it. factor > 1 is a fan-out (e.g. ParameterBindingStage, PauliTwirlStage); factor < 1 is a reduction (e.g. observable grouping in MeasurementStage collapsing N Pauli terms into M ≤ N commuting groups yields factor = M / N).
