ConvertIdToDelay

class ConvertIdToDelay(*args, **kwargs)[source]

Bases: TransformationPass

Convert qiskit.circuit.library.standard_gates.IGate to a delay of the corresponding length.

Convert qiskit.circuit.library.IGate to a Convert qiskit.circuit.Delay.

Parameters:

  • duration – Duration of the delay to replace the identity gate with.

  • gate – Single qubit gate to extract duration from.

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

__call__(circuit, property_set=None)

Runs the pass on circuit.

Parameters:

  • circuit (QuantumCircuit) – The dag on which the pass is run.

  • property_set (PropertySet | dict | None) – Input/output property set. An analysis pass might change the property set in-place. If not given, the existing property_set attribute of the pass will be used (if set).

Returns:

If on transformation pass, the resulting QuantumCircuit. If analysis pass, the input circuit.

Return type:

QuantumCircuit

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, PassManagerState]

name()

Name of the pass.

Return type:

str

run(dag)[source]

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.

Return type:

DAGCircuit

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
