PRX_ModulatedCustomWaveForms

PRX_ModulatedCustomWaveForms#

class iqm.pulse.gates.prx.PRX_ModulatedCustomWaveForms(parent, name, locus, calibration_data, builder)#

Bases: PRX_CustomWaveforms

Base class for PRX gates with modulated frequency, hot-swappable waveforms.

The class takes baseband I and Q waveform as input, and modulates them with frequency in the root_parameters. The final pulse shape after modulation is:

\[A_I^{\delta}\Omega_I(t)\cos((\omega_d + \delta)t) - A_Q^{\delta}\Omega_Q(t)\sin((\omega_d + \delta)t)\]

where \(A_I\) is amplitude_i, \(A_Q\) is amplitude_q, \(\Omega\) is arbitrary waveform in baseband, \(\omega_d/2\pi\) is the drive frequency and \(\delta/2\pi\) is the modulated frequency.

Module: iqm.pulse.gates.prx

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

Parameters:
root_parameters: dict[str, Parameter | Setting] = {'amplitude_i': Parameter(name='', label='pi pulse amplitude of base band I waveform', unit='', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'amplitude_q': Parameter(name='', label='pi pulse amplitude of base band Q waveform', unit='', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'duration': Parameter(name='', label='pi pulse duration', unit='s', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'frequency': Parameter(name='', label='modulated pulse frequency', unit='Hz', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None)}#

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

classmethod _get_pulse(*, amplitude_i, amplitude_q, n_samples, **rest_of_calibration_data)#

Return the IQPulse with modulated arbitrary waveform based on the calibration data.

Parameters:
Return type:

IQPulse

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.
