QBBias_Measure_CustomWaveforms

Module: iqm.pulse.gates.measure

class iqm.pulse.gates.measure.QBBias_Measure_CustomWaveforms(parent, name, locus, calibration_data, builder)

Bases: Measure_CustomWaveforms

Base class of a measure with an additional fast flux voltage pulse to bias the measured qubit.

Attributes

dependent_waves	If set True, the Q channel waveform is considered to depend on the I channel's waveform so that they share the waveform parameters, (e.g. a DRAG PRX implementation).
root_parameters	Parameters independent of the of Waveforms.
wave_i	Waveform for the I channel.
wave_q	Waveform for the Q channel.
id	Unique str identifier, needed for certain caching properties.
sub_implementations	Single-component sub-implementations for factorizable gates with len(locus) > 1, otherwise empty.

Methods

get_additional_components
locus_mapping_function	One-qubit loci with readout and fast flux.

Parameters:

• parent (QuantumOp)

• name (str)

• locus (Locus)

• calibration_data (OILCalibrationData)

• builder (ScheduleBuilder)

locus_mapping_function()

One-qubit loci with readout and fast flux.

Parameters:

Parameters independent of the of Waveforms. Inheriting classes may override this to include parameters common to all such implementations.

dependent_waves: bool = True

If set True, the Q channel waveform is considered to depend on the I channel’s waveform so that they share the waveform parameters, (e.g. a DRAG PRX implementation). If not provided, will be initialised as True.
