Methods
from_instruction
static from_instruction(instruction, /, *, dag=None, deepcopy=False)
is_control_flow
is_control_flow()
Is the Operation contained in this node a control-flow operation (i.e. an instance of ControlFlowOp)?
is_controlled_gate
is_controlled_gate()
Is the Operation contained in this node a subclass of ControlledGate?
is_directive
is_directive()
Is the Operation contained in this node a directive?
is_parameterized
is_parameterized()
Does this node contain any ParameterExpression parameters?
is_standard_gate
is_standard_gate()
Is the Operation contained in this node a Qiskit standard gate?
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
