InverseCancellation

class qiskit.transpiler.passes.InverseCancellation(*args, **kwargs)

Bases: TransformationPass

Cancel specific Gates which are inverses of each other when they occur back-to- back.

Initialize InverseCancellation pass.

প্যারামিটার:

gates_to_cancel -- list of gates to cancel

রেইজেস:

TranspilerError -- Initialization raises an error when the input is not a self-inverse gate or a two-tuple of inverse gates.

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).

Methods

name()

Return the name of the pass.

run(dag)

Run the InverseCancellation pass on dag.

প্যারামিটার:

dag (DAGCircuit) -- the directed acyclic graph to run on.

রিটার্নস:

Transformed DAG.
