TrivialF2QLayout

class TrivialF2QLayout

Bases: GenericPass[DAGCircuit, DAGCircuit]

Trivially maps \(n\) fermionic modes to \(n\) qubits.

This pass simply populates the f2q_layout field of the property_set, with a dictionary associating each FermionicRegister with an equally sized QuantumRegister.

Methods

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:

DAGCircuit

Inherited Methods

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()

Name of the pass.

Return type:

str

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
