qiskit.transpiler.passes.CheckMap

class CheckMap(*args, **kwargs)

Check if a DAG circuit is already mapped to a coupling map.

Check if a DAGCircuit is mapped to coupling_map by checking that all 2-qubit interactions are laid out to be physically close, setting the property is_swap_mapped to True or False accordingly.

CheckMap initializer.

Parameters

coupling_map (CouplingMap) – Directed graph representing a coupling map.

__init__(coupling_map)

CheckMap initializer.

Parameters

coupling_map (CouplingMap) – Directed graph representing a coupling map.

Methods

__init__(coupling_map)	CheckMap initializer.
name()	Return the name of the pass.
run(dag)	Run the CheckMap 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 CheckMap pass on dag.

If dag is mapped to coupling_map, the property is_swap_mapped is set to True (or to False otherwise).

Parameters

dag (DAGCircuit) – DAG to map.
