<Function id="qiskit.pulse.builder.align_sequential" isDedicatedPage={true} github="https://github.com/qiskit/qiskit/tree/stable/0.22/qiskit/pulse/builder.py" signature="align_sequential()">
|
|
Sequential alignment pulse scheduling context.
|
|
|
|
Pulse instructions within this context are scheduled sequentially in time such that no two instructions will be played at the same time.
|
|
|
|
Examples:
|
|
|
|
```python
|
|
from qiskit import pulse
|
|
|
|
d0 = pulse.DriveChannel(0)
|
|
d1 = pulse.DriveChannel(1)
|
|
|
|
with pulse.build() as pulse_prog:
|
|
with pulse.align_sequential():
|
|
# this pulse will start at t=0
|
|
pulse.play(pulse.Constant(100, 1.0), d0)
|
|
# this pulse will also start at t=100
|
|
pulse.play(pulse.Constant(20, 1.0), d1)
|
|
pulse_prog = pulse.transforms.block_to_schedule(pulse_prog)
|
|
|
|
assert pulse_prog.ch_stop_time(d0) == pulse_prog.ch_start_time(d1)
|
|
```
|
|
|
|
