LinearFunctionsSynthesis
class qiskit.transpiler.passes.LinearFunctionsSynthesis(*args, **kwargs)
Bases: HighLevelSynthesis
DEPRECATED: Synthesize linear functions.
Under the hood, this runs the default high-level synthesis plugin for linear functions.
The class qiskit.transpiler.passes.synthesis.linear_functions_synthesis.LinearFunctionsSynthesis is deprecated as of qiskit-terra 0.23.0. It will be removed no earlier than 3 months after the release date. Instead, use HighLevelSynthesis.
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 | None) – A callback function which is caller per execution of optimization task.
Returns
Optimized Qiskit IR and state of the workflow.
Return type
tuple[Any, qiskit.passmanager.compilation_status.PassManagerState]
name
run
run(dag)
Run the HighLevelSynthesis pass on dag.
Parameters
dag (DAGCircuit) – input dag.
Returns
Output dag with higher-level operations synthesized.
Raises
- TranspilerError – when the transpiler is unable to synthesize the given DAG
- (for instance, when the specified synthesis method is not available)****. –
Return type
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.
