qiskit.transpiler.passes.CheckCXDirection
class CheckCXDirection(*args, **kwargs)
Deprecated: use qiskit.transpiler.passes.CheckGateDirection pass instead.
CheckGateDirection initializer.
Parameters
coupling_map (CouplingMap) – Directed graph representing a coupling map.
__init__
__init__(coupling_map)
CheckGateDirection initializer.
Parameters
coupling_map (CouplingMap) – Directed graph representing a coupling map.
Methods
__init__(coupling_map) | CheckGateDirection initializer. |
name() | Return the name of the pass. |
run(dag) | Run the CheckGateDirection 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 CheckGateDirection pass on dag.
If dag is mapped and the direction is correct the property is_direction_mapped is set to True (or to False otherwise).
Parameters
dag (DAGCircuit) – DAG to check.
