Decompose
class Decompose(gate=None, gates_to_decompose=None)
Bases: qiskit.transpiler.basepasses.TransformationPass
Expand a gate in a circuit using its decomposition rules.
Decompose initializer.
Parameters
- gate (
Optional[Type[Gate]]) – DEPRECATED gate to decompose. - gates_to_decompose (
Union[Type[Gate],List[Type[Gate]],List[str],str,None]) – optional subset of gates to be decomposed, identified by gate label, name or type. Defaults to all gates.
Methods
name
Decompose.name()
Return the name of the pass.
run
Decompose.run(dag)
Run the Decompose pass on dag.
Parameters
dag (DAGCircuit) – input dag.
Return type
DAGCircuit
Returns
output dag where gate was expanded.
Attributes
gate
Returns the gate
Return type
Gate
is_analysis_pass
Check if the pass is an analysis pass.
If the pass is an AnalysisPass, that means that the pass can analyze the DAG and write the results of that analysis in the property set. Modifications on the DAG are not allowed by this kind of pass.
is_transformation_pass
Check if the pass is a transformation pass.
If the pass is a TransformationPass, that means that the pass can manipulate the DAG, but cannot modify the property set (but it can be read).
