|
|
A new method :meth:`~qiskit.dagcircuit.DAGCircuit.compose` has been added to
|
|
the :class:`~qiskit.dagcircuit.DAGCircuit` class for composing two circuits
|
|
via their DAGs.

dag_left.compose(dag_right, edge_map={right_qubit0: self.left_qubit1,
|
|
right_qubit1: self.left_qubit4,
|
|
right_clbit0: self.left_clbit1,
|
|
right_clbit1: self.left_clbit0})

deprecations:
|
|
- |
|
|
The ``DAGCircuit.compose_back()`` and ``DAGCircuit.extend_back()`` methods
|
|
are deprecated and will be removed in a future release. Instead you should
|
|
use the :meth:`qiskit.dagcircuit.DAGCircuit.compose` method, which is a more
|
|
general and more flexible method that provides the same functionality.
