qiskit.transpiler.passes.UnrollCustomDefinitions
class UnrollCustomDefinitions(*args, **kwargs)
Unrolls instructions with custom definitions.
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 (list[str]) – Target basis names to unroll to, e.g. [‘u3’, ‘cx’].
__init__
__init__(equivalence_library, basis_gates)
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 (list[str]) – Target basis names to unroll to, e.g. [‘u3’, ‘cx’].
Methods
__init__(equivalence_library, basis_gates) | Unrolls instructions with custom definitions. |
name() | Return the name of the pass. |
run(dag) | Run the UnrollCustomDefinitions 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. |
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).
name
name()
Return the name of the pass.
run
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
