A transformer that expands composite operations via cirq.decompose.

Used in the notebooks

Used in the tutorials

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.
