DAGDepNode
class DAGDepNode(type=None, op=None, name=None, qargs=None, cargs=None, condition=None, successors=None, predecessors=None, reachable=None, matchedwith=None, successorstovisit=None, isblocked=None, qindices=None, cindices=None, nid=- 1)
Bases: object
Object to represent the information at a node in the DAGDependency().
It is used as the return value from *_nodes() functions and can be supplied to functions that take a node.
Methods
copy
DAGDepNode.copy()
Function to copy a DAGDepNode object. :returns: a copy of a DAGDepNode object. :rtype: DAGDepNode
semantic_eq
static DAGDepNode.semantic_eq(node1, node2)
Check if DAG nodes are considered equivalent, e.g., as a node_match for nx.is_isomorphic.
Parameters
- node1 (DAGDepNode) – A node to compare.
- node2 (DAGDepNode) – The other node to compare.
Returns
If node1 == node2
Return type
Bool
Attributes
cargs
cindices
condition
Returns the condition of the node.op
isblocked
matchedwith
name
node_id
op
Returns the Instruction object corresponding to the op for the node, else None
predecessors
qargs
Returns list of Qubit, else an empty list.
