DAGNode
DAGNode(type=None, op=None, name=None, qargs=None, cargs=None, wire=None, nid=- 1)
Bases: object
Parent class for DAGOpNode, DAGInNode, and DAGOutNode.
Create a node
Methods
semantic_eq
static DAGNode.semantic_eq(node1, node2, bit_indices1=None, bit_indices2=None)
Check if DAG nodes are considered equivalent, e.g., as a node_match for nx.is_isomorphic.
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
Attributes
cargs
Returns list of Clbit, else an empty list.
condition
Returns the condition of the node.op
name
Returns the Instruction name corresponding to the op for this node
op
Returns the Instruction object corresponding to the op for the node, else None
qargs
Returns list of Qubit, else an empty list.
type
Returns the type object
wire
Returns the Bit object, else None.
