DAGOpNode

class qiskit.dagcircuit.DAGOpNode(op, qargs=(), cargs=(), dag=None)

Bases: DAGNode

Object to represent an Instruction at a node in the DAGCircuit.

Create an Instruction node

Attributes

op

qargs

cargs

sort_key

name

Returns the Instruction name corresponding to the op for this node

Methods

semantic_eq

static semantic_eq(node1, node2, bit_indices1, bit_indices2)

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
