Layout2qDistance
class Layout2qDistance(*args, **kwargs)
Bases: qiskit.transpiler.basepasses.AnalysisPass
Evaluate how good the layout selection was.
Saves in property_set[‘layout_score’] (or the property name in property_name) the sum of distances for each circuit CX. The lower the number, the better the selection. Therefore, 0 is a perfect layout selection. No CX direction is considered.
Layout2qDistance initializer.
Parameters
- coupling_map (CouplingMap) – Directed graph represented a coupling map.
- property_name (str) – The property name to save the score. Default: layout_score
Methods
name
Layout2qDistance.name()
Return the name of the pass.
run
Layout2qDistance.run(dag)
Run the Layout2qDistance pass on dag. :param dag: DAG to evaluate. :type dag: 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).
