cirq.expand_composite

A transformer that expands composite operations via cirq.decompose.

cirq.expand_composite(
    circuit: 'cirq.AbstractCircuit',
    *,
    context: Optional['cirq.TransformerContext'] = None,
    no_decomp: Callable[[cirq.Operation], bool] = (lambda _: False)
)

For each operation in the circuit, this pass examines if the operation can be decomposed. If it can be, the operation is cleared out and replaced with its decomposition using a fixed insertion strategy.

Transformation is applied using cirq.map_operations_and_unroll, which preserves the moment structure of the input circuit.

circuit Input circuit to transform.
context cirq.TransformerContext storing common configurable options for transformers.
no_decomp A predicate that determines whether an operation should be decomposed or not. Defaults to decomposing everything.
