qiskit.dagcircuit.DAGNode

class DAGNode(type=None, op=None, name=None, qargs=None, cargs=None, condition=None, wire=None, nid=- 1)

Object to represent the information at a node in the DAGCircuit.

It is used as the return value from *_nodes() functions and can be supplied to functions that take a node.

Create a node

__init__(type=None, op=None, name=None, qargs=None, cargs=None, condition=None, wire=None, nid=- 1)

Create a node

Methods

__init__([type, op, name, qargs, cargs, …])	Create a node
semantic_eq(node1, node2)	Check if DAG nodes are considered equivalent, e.g., as a node_match for nx.is_isomorphic.

Attributes

cargs
condition
name
op	Returns the Instruction object corresponding to the op for the node, else None
qargs	Returns list of Qubit, else an empty list.
sort_key
type
wire	Returns the Bit object, else None.

property op

Returns the Instruction object corresponding to the op for the node, else None

property qargs

Returns list of Qubit, else an empty list.

static semantic_eq(node1, node2)
