qiskit.transpiler.passes.Decompose

class Decompose(gate=None)

Expand a gate in a circuit using its decomposition rules.

Decompose initializer.

Parameters

gate (Optional[Type[Gate]]) – gate to decompose.

__init__(gate=None)

Decompose initializer.

Parameters

gate (Optional[Type[Gate]]) – gate to decompose.

Methods

__init__([gate])	Decompose initializer.
name()	Return the name of the pass.
run(dag)	Run the Decompose pass on dag.

Attributes

is_analysis_pass	Check if the pass is an analysis pass.
is_transformation_pass	Check if the pass is a transformation pass.

property 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.

property 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).

name()

Return the name of the pass.

run(dag)

Run the Decompose pass on dag.

Parameters

dag (DAGCircuit) – input dag.

Return type

DAGCircuit

Returns

output dag where gate was expanded.
