|
A new version of the providers interface has been added. This new interface,
|
|
which can be found in :mod:`qiskit.providers`, provides a new versioning
|
|
mechanism that will enable changes to the interface to happen in a
|
|
compatible manner over time. The new interface should be simple to migrate
|
|
existing providers, as it is mostly identical except for the explicit
|
|
versioning.
|
|
|
|
Besides having explicitly versioned abstract classes the key changes for
|
|
the new interface are that the :class:`~qiskit.providers.BackendV1`
|
|
method :meth:`~qiskit.providers.BackendV1.run` can now
|
|
take a :class:`~qiskit.circuits.QuantumCircuit` or
|
|
:class:`~qiskit.pulse.Schedule` object as inputs instead of ``Qobj``
|
|
objects. To go along with that options are now part of a backend class
|
|
so that users can configure run time options when running with a circuit.
|
|
The final change is that :class:`qiskit.providers.JobV1` can now be
|
|
synchronous or asynchronous, the exact configuration and method for
|
|
configuring this is up to the provider, but there are interface hook
|
|
points to make it explicit which execution model a job is running under
|
|
in the ``JobV1`` abstract class.
