GitHub

Bases: qiskit.transpiler.basepasses.TransformationPass

Unrolls instructions with custom definitions.

Parameters

equivalence_library (EquivalenceLibrary) – The equivalence library which will be used by the BasisTranslator pass. (Instructions in this library will not be unrolled by this pass.)
basis_gates (Optional[list[str]]) – Target basis names to unroll to, e.g. [‘u3’, ‘cx’]. Ignored if target is also specified.
target (Optional[Target]) – The Target object corresponding to the compilation target. When specified, any argument specified for basis_gates is ignored.

Methods

name

UnrollCustomDefinitions.name()

Return the name of the pass.

run

UnrollCustomDefinitions.run(dag)

Run the UnrollCustomDefinitions pass on dag.

Parameters

dag (DAGCircuit) – input dag

Raises

QiskitError – if unable to unroll given the basis due to undefined
decomposition rules** (such as a bad basis) or **excessive recursion. –

Returns

output unrolled dag

Return type

DAGCircuit

Attributes

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).
