AIPermutationSynthesis
class qiskit_ibm_transpiler.ai.AIPermutationSynthesis(backend_name: str, replace_only_if_better: bool = True, max_threads: int | None = None)
Bases: AISynthesis
Synthesis for Permutation circuits (blocks of SWAP gates). Currently available for 65, 33, and 27 qubit blocks.
Parameters
- backend_name (str) – Name of the backend used for doing the AI Linear Function synthesis.
- replace_only_if_better (bool, optional) – Determine if replace the original circuit with the synthesized one if it’s better, defaults to True.
- max_threads (int, optional) – Set the number of requests to send in parallel.
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
execute
execute(passmanager_ir, state, callback=None)
Execute optimization task for input Qiskit IR.
Parameters
- passmanager_ir (Any) – Qiskit IR to optimize.
- state (PassManagerState) – State associated with workflow execution by the pass manager itself.
- callback (Callable) – A callback function which is caller per execution of optimization task.
Returns
Optimized Qiskit IR and state of the workflow.
Return type
name
run
run(dag)
Run a pass on the DAGCircuit. This is implemented by the pass developer.
Parameters
dag (DAGCircuit) – the dag on which the pass is run.
Raises
NotImplementedError – when this is left unimplemented for a pass.
synth_nodes
synth_nodes(nodes)
update_status
update_status(state, run_state)
Update workflow status.
Parameters
- state (PassManagerState) – Pass manager state to update.
- run_state (RunState) – Completion status of current task.
Returns
Updated pass manager state.
