ConvertIdToDelay
class ConvertIdToDelay(durations, gate='sx')
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 (
str) – 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__
__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.
Return type
QuantumCircuit
Returns
If on transformation pass, the resulting QuantumCircuit. If analysis pass, the input circuit.
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 (
Optional[Callable]) – A callback function which is caller per execution of optimization task.
Return type
tuple[Any, PassManagerState]
Returns
Optimized Qiskit IR and state of the workflow.
name
name()
Name of the pass.
Return type
str
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.
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.
Return type
PassManagerState
Returns
Updated pass manager state.
