Module Contents#

class LatchReset(portclock: tuple[str, str], t0: float = 0, duration: float = 4e-09)[source]#

Bases: qblox_scheduler.operations.hardware_operations.pulse_library.LatchReset

Operation that resets the feedback trigger addresses from the hardware.

Currently only implemented for Qblox backend, refer to ResetFeedbackTriggersStrategy for more details.

class SimpleNumericalPulse(samples: numpy.ndarray | list, port: str, clock: str = BasebandClockResource.IDENTITY, gain: complex | float | operations.expressions.Expression | collections.abc.Sequence[complex | float | operations.expressions.Expression] = 1, reference_magnitude: qblox_scheduler.operations.pulse_library.ReferenceMagnitude | None = None, t0: float = 0)[source]#

Bases: qblox_scheduler.operations.hardware_operations.pulse_library.SimpleNumericalPulse

Wrapper on top of NumericalPulse to provide a simple interface for creating a pulse where the samples correspond 1:1 to the produced waveform, without needing to specify the time samples.

Parameters:

  • samples – An array of (possibly complex) values specifying the shape of the pulse.

  • port – The port that the pulse should be played on.

  • clock – Clock used to (de)modulate the pulse. By default the baseband clock.

  • gain – Gain factor between -1 and 1 that multiplies with the samples, by default 1.

  • reference_magnitude – Scaling value and unit for the unitless samples. Uses settings in hardware config if not provided.

  • t0 – Time in seconds when to start the pulses relative to the start time of the Operation in the TimeableSchedule.

Example

from qblox_scheduler.operations.hardware_operations.pulse_library import (
    SimpleNumericalPulse
)
from qblox_scheduler import TimeableSchedule

waveform = [0.1,0.2,0.2,0.3,0.5,0.4]

schedule = TimeableSchedule("")
schedule.add(SimpleNumericalPulse(waveform, port="q0:out"))
