upgrade:
|
|
- |
|
|
The pulse ``buffer`` option found in :class:`qiskit.pulse.Channel` and
|
|
:class:`qiskit.pulse.Schedule` was deprecated in Terra 0.11.0 and has now
|
|
been removed. To add a delay on a channel or in a schedule, specify it
|
|
explicitly in your Schedule with a Delay::
|
|
|
|
sched = Schedule()
|
|
sched += Delay(5)(DriveChannel(0))
|
|
- |
|
|
``PulseChannelSpec``, which was deprecated in Terra 0.11.0, has now been
|
|
removed. Use BackendConfiguration instead::
|
|
|
|
config = backend.configuration()
|
|
drive_chan_0 = config.drives(0)
|
|
acq_chan_0 = config.acquires(0)
|
|
|
|
or, simply reference the channel directly, such as ``DriveChannel(index)``.
|
|
- |
|
|
An import path was deprecated in Terra 0.10.0 and has now been removed: for
|
|
``PulseChannel``, ``DriveChannel``, ``MeasureChannel``, and
|
|
``ControlChannel``, use ``from qiskit.pulse.channels import X`` in place of
|
|
``from qiskit.pulse.channels.pulse_channels import X``.
