DAGOpNode

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

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

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
