# CheckMap
|
||
|
||
<Class id="qiskit.transpiler.passes.CheckMap" isDedicatedPage={true} github="https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/transpiler/passes/utils/check_map.py#L21-L94" signature="qiskit.transpiler.passes.CheckMap(*args, **kwargs)" modifiers="class">
|
||
Bases: [`AnalysisPass`](qiskit.transpiler.AnalysisPass "qiskit.transpiler.basepasses.AnalysisPass")
|
||
|
||
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 on adjacent qubits in the global coupling map of the device, setting the property set field (either specified with `property_set_field` or the default `is_swap_mapped`) to `True` or `False` accordingly. Note this does not validate directionality of the connectivity between qubits. If you need to check gates are implemented in a native direction for a target use the [`CheckGateDirection`](qiskit.transpiler.passes.CheckGateDirection "qiskit.transpiler.passes.CheckGateDirection") pass instead.
|
||
|
||
CheckMap initializer.
|
||
|
||
**Parameters**
|
||
|
||
* **coupling\_map** (*Union\[*[*CouplingMap*](qiskit.transpiler.CouplingMap "qiskit.transpiler.CouplingMap")*,* [*Target*](qiskit.transpiler.Target "qiskit.transpiler.Target")*]*) – Directed graph representing a coupling map.
|
||
* **property\_set\_field** ([*str*](https://docs.python.org/3/library/stdtypes.html#str "(in Python v3.12)")) – An optional string to specify the property set field to store the result of the check. If not default the result is stored in `"is_swap_mapped"`.
|
||
|
||
## Attributes
|
||
|
||
### is\_analysis\_pass
|
||
|
||
<Attribute id="qiskit.transpiler.passes.CheckMap.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.
|
||
</Attribute>
|
||
|
||
### is\_transformation\_pass
|
||
|
||
<Attribute id="qiskit.transpiler.passes.CheckMap.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).
|
||
</Attribute>
|
||
|
||
## Methods
|
||
|
||
### execute
|
||
|
||
<Function id="qiskit.transpiler.passes.CheckMap.execute" github="https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/passmanager/base_tasks.py#L72-L118" signature="execute(passmanager_ir, state, callback=None)">
|
||

|
||
|
||
**Parameters**
|
||
|
||
* **passmanager\_ir** ([*Any*](https://docs.python.org/3/library/typing.html#typing.Any "(in Python v3.12)")) – Qiskit IR to optimize.
|
||
* **state** ([*PassManagerState*](qiskit.passmanager.PassManagerState "qiskit.passmanager.compilation_status.PassManagerState")) – State associated with workflow execution by the pass manager itself.
|
||
* **callback** ([*Callable*](https://docs.python.org/3/library/collections.abc.html#collections.abc.Callable "(in Python v3.12)") *| None*) – A callback function which is caller per execution of optimization task.
|
||
|
||
**Returns**
|
||
|
||
Optimized Qiskit IR and state of the workflow.
|
||
|
||
**Return type**
