LinearFunctionsSynthesis

qiskit.transpiler.passes.LinearFunctionsSynthesis(*args, **kwargs) GitHub(opens in a new tab)

Bases: HighLevelSynthesis

DEPRECATED: Synthesize linear functions.

Under the hood, this runs the default high-level synthesis plugin for linear functions.

Deprecated since version 0.23.0

The class qiskit.transpiler.passes.synthesis.linear_functions_synthesis.LinearFunctionsSynthesis is deprecated as of qiskit-terra 0.23.0. It will be removed in the Qiskit 1.0 release. 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

Returns

Optimized Qiskit IR and state of the workflow.

Return type

tuple(opens in a new tab)[Any(opens in a new tab), qiskit.passmanager.compilation_status.PassManagerState]

name

name()

Name of the pass.

Return type

str(opens in a new tab)

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

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.

Return type

PassManagerState
