tsim.core.graph.prepare_graph

Signature

def prepare_graph(circuit: Circuit, *, sample_detectors: bool) -> SamplingGraph

Public import paths

• from tsim.sampler import prepare_graph

Prepare a circuit for compilation.

This function performs the graph preparation phase:

1. Parse the stim circuit into a ZX graph
2. Build the sampling graph (compose with adjoint, add outputs)
3. Reduce the graph via zx.full_reduce
4. Transform error basis via Gaussian elimination (e → f)
5. Clear the scalar (safe before stabilizer rank decomposition)

Parameters

Name	Type	Description
circuit	Circuit	The quantum circuit to prepare.
sample_detectors	bool	If True, prepare for detector sampling. If False, prepare for measurement sampling.

Returns

SamplingGraphA SamplingGraph containing the reduced graph and error transformation.
