qiskit.pulse.builder.pad

pad(*chs)

Pad all availale timeslots with delays upon exiting context.

Parameters

chs (Channel) – Channels to pad with delays. Defaults to all channels in context if none are supplied.

Examples:

from qiskit import pulse

d0 = pulse.DriveChannel(0)
d1 = pulse.DriveChannel(1)

with pulse.build() as pulse_prog:
    with pulse.pad():
        with pulse.align_right():
            # this pulse will start at t=0
            pulse.play(pulse.Constant(100, 1.0), d0)
            # this pulse will start at t=80
            # a delay will be inserted from t=0 to t=80
            pulse.play(pulse.Constant(20, 1.0), d1)
assert pulse_prog.ch_start_time(d0) == pulse_prog.ch_start_time(d1)
assert pulse_prog.ch_stop_time(d0) == pulse_prog.ch_stop_time(d1)

Return type

AbstractContextManager[None]
