CollectLinearFunctions
class qiskit_transpiler_service.ai.CollectLinearFunctions(do_commutative_analysis: bool = True, min_block_size: int = 4, max_block_size: int = LINEAR_MAX_BLOCK_SIZE, collect_from_back: bool = False, num_reps: int = 10)
Bases: RepeatedCollectAndCollapse
Collects blocks of SWAP and CX as LinearFunction objects and stores the original sub-circuit to compare against it after synthesis.
Parameters
- do_commutative_analysis (bool(opens in a new tab), optional) – Enable or disable commutative analysis, defaults to True
- min_block_size (int(opens in a new tab), optional) – Set the minimum size for blocks generated during the collect linear functions pass, defaults to 4.
- max_block_size (int(opens in a new tab), optional) – Set the maximum size for blocks generated during the collect linear functions pass, defaults to 9.
- collect_from_back (bool(opens in a new tab), optional) – Specify if collect blocks in reverse order or not, defaults to False.
- num_reps (int(opens in a new tab), optional) – Specify how many times to repeat the optimization process, defaults to 10.
Methods
execute
execute(passmanager_ir, state, callback=None)
Execute optimization task for input Qiskit IR.
Parameters
- passmanager_ir (Any(opens in a new tab)) – Qiskit IR to optimize.
- state (PassManagerState) – State associated with workflow execution by the pass manager itself.
- callback (Callable(opens in a new tab) | None) – A callback function which is caller per execution of optimization task.
Returns
Optimized Qiskit IR and state of the workflow.
Return type
tuple(opens in a new tab)[Any(opens in a new tab), PassManagerState]
name
run
run(dag)
Run the CollectLinearFunctions pass on dag. :param dag: the DAG to be optimized. :type dag: DAGCircuit
Returns
the optimized DAG.
Return type
DAGCircuit
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.
