DAGNode¶

class qiskit.dagcircuit.DAGNode(nid=-1)[source]¶

Parent class for DAGOpNode, DAGInNode, and DAGOutNode.

Create a node

Methods

static semantic_eq(node1, node2, bit_indices1, bit_indices2)[source]¶

Check if DAG nodes are considered equivalent, e.g., as a node_match for rustworkx.is_isomorphic_node_match().

Parameters:

node1 (DAGOpNode, DAGInNode, DAGOutNode) – A node to compare.
node2 (DAGOpNode, DAGInNode, DAGOutNode) – The other node to compare.
bit_indices1 (dict) – Dictionary mapping Bit instances to their index within the circuit containing node1
bit_indices2 (dict) – Dictionary mapping Bit instances to their index within the circuit containing node2

Returns:

If node1 == node2

Return type:

Bool
