CustomF2QLayout
class CustomF2QLayout(layout)
Bases: GenericPass[DAGCircuit, DAGCircuit]
Sets the user-provided F2QLayout in the transpiler.
This pass simply populates the f2q_layout field of the property_set, with the value of layout.
It is the user’s responsibility to ensure that subsequently used transpilation passes (and plugins) are configured to adhere to this F2QLayout correctly.
Initializing this transpiler pass can be done with the arguments listed below.
Parameters
layout (F2QLayout) – the custom f2q_layout to use.
Attributes
layout
Type: F2QLayout
The user-provided mapping of FermionicRegister to QuantumRegister.
Methods
run
run(dag)
Runs this analysis pass.
Parameters
dag (DAGCircuit) – the DAG circuit representation of a FermionicCircuit.
Returns
The unchanged input. But the property_set of this transpilation pipeline will be updated.
Return type
Inherited Methods
execute
execute(passmanager_ir, state, callback=None)
Execute optimization task for input Qiskit IR.
Parameters
- passmanager_ir (IR) – Qiskit IR to optimize.
- state (PassManagerState) – State associated with workflow execution by the pass manager itself.
- callback (Callable[[Task, IR_OUT, PropertySet, float, int], None] | None) – A callback function which is called per execution of optimization task.
Returns
Optimized Qiskit IR and state of the workflow.
Return type
tuple[IR_OUT, PassManagerState]
name
update_status
update_status(state, run_state)
Update workflow status.
Parameters
- state (PassManagerState) – Pass manager state to update.
