qiskit.transpiler.passes.CheckGateDirection

class CheckGateDirection(*args, **kwargs)

Check if the two-qubit gates follow the right direction with respect to the coupling map.

CheckGateDirection initializer.

Parameters

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

__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.

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 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.
