DAG Circuits

DAGCircuit()	Quantum circuit as a directed acyclic graph.
DAGNode([nid])	Parent class for DAGOpNode, DAGInNode, and DAGOutNode.
DAGOpNode(op[, qargs, cargs])	Object to represent an Instruction at a node in the DAGCircuit.
DAGInNode(wire)	Object to represent an incoming wire node in the DAGCircuit.
DAGOutNode(wire)	Object to represent an outgoing wire node in the DAGCircuit.
DAGDepNode([type, op, name, qargs, cargs, ...])	Object to represent the information at a node in the DAGDependency().
DAGDependency()	Object to represent a quantum circuit as a directed acyclic graph via operation dependencies (i.e.
