ParallelDo

class ParallelDo(pass_sequences, less_than, pick_first=False)

Bases: BasePass

The ParallelDo class.

This is a control pass that executes a sequence of workflows in parallel. The branch that is accepted can either be the first to complete or one selected by a provided ordering.

__init__(pass_sequences, less_than, pick_first=False)

Construct a ParallelDo.

Parameters:

• pass_sequences (Iterable[Workflow | Iterable[BasePass] | BasePass]) – The group of workflows to run in parallel.

• less_than (Callable[[Circuit, Circuit], bool]) – Return True if the first circuit is preferred to the second one. This will be used to determine which output circuit to select.

• pick_first (bool) – If true, then the pass will complete as soon as one of the workflows finishes and will return the first result. Defaults to False.

Attributes

name	The name of the pass.

Methods

execute(*args, **kwargs)	Map a function over iterable arguments in parallel.
get_connectivity(_, data)	Retrieve the current connectivity of the circuit.
get_model(_, data)	Retrieve the machine model from the data dictionary.
get_placement(_, data)	Retrieve the logical to physical qubit map from the data dictionary.
get_target(_, data)	Retrieve the target from the data dictionary.
in_parallel(data)	Return true if pass is being executed in a parallel.
run(circuit, data)	Perform the pass's operation, see BasePass for more.
