qiskit.pulse.builder.align_left
align_left()
Left alignment pulse scheduling context.
Pulse instructions within this context are scheduled as early as possible by shifting them left to the earliest available time.
Examples:
from qiskit import pulse
d0 = pulse.DriveChannel(0)
d1 = pulse.DriveChannel(1)
with pulse.build() as pulse_prog:
with pulse.align_left():
# this pulse will start at t=0
pulse.play(pulse.Constant(100, 1.0), d0)
# this pulse will start at t=0
pulse.play(pulse.Constant(20, 1.0), d1)
pulse_prog = pulse.transforms.block_to_schedule(pulse_prog)
assert pulse_prog.ch_start_time(d0) == pulse_prog.ch_start_time(d1)Yields
None
Return type
AbstractContextManager[None]
