qiskit.dagcircuit.DAGCircuit.substitute_node_with_dag

DAGCircuit.substitute_node_with_dag(node, input_dag, wires=None, propagate_condition=True)

Replace one node with dag.

Paramètres

• node (DAGOpNode) – node to substitute

• input_dag (DAGCircuit) – circuit that will substitute the node

• wires (list[Bit] | Dict[Bit, Bit]) – gives an order for (qu)bits in the input circuit. If a list, then the bits refer to those in the input_dag, and the order gets matched to the node wires by qargs first, then cargs, then conditions. If a dictionary, then a mapping of bits in the input_dag to those that the node acts on.

• propagate_condition (bool) – If True (default), then any condition attribute on the operation within node is propagated to each node in the input_dag. If False, then the input_dag is assumed to faithfully implement suitable conditional logic already.

Renvoie

maps node IDs from input_dag to their new node incarnations in self.
