DAG Circuits (qiskit.dagcircuit)#

Circuits as Directed Acyclic Graphs#

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 (DAG) via operation dependencies (i.e.

Exceptions#

exception qiskit.dagcircuit.DAGCircuitError(*msg)[código fonte]#

Base class for errors raised by the DAGCircuit object.

Set the error message.

exception qiskit.dagcircuit.DAGDependencyError(*msg)[código fonte]#

Base class for errors raised by the DAGDependency object.

Set the error message.

Utilities#

BlockCollapser(dag)

This class implements various strategies of consolidating blocks of nodes in a DAG (direct acyclic graph).

BlockCollector(dag)

This class implements various strategies of dividing a DAG (direct acyclic graph) into blocks of nodes that satisfy certain criteria.

BlockSplitter()

Splits a block of nodes into sub-blocks over disjoint qubits.
