Fast_Measure_Constant

Module: iqm.pulse.gates.measure

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

Bases: Fast_Measure_CustomWaveforms

Implementation of a faster measure with constant i and q waveforms.

Does not block the drive and flux channels of the locus qubits during the integration, but just during the probe pulse and extra calibrated dead time after it.

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).
parameters	Required calibration data, may be nested
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

Parameters:

• parent (QuantumOp)

• name (str)

• locus (Locus)

• calibration_data (OILCalibrationData)

• builder (ScheduleBuilder)

dependent_waves = 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.
