ProbePulse_CustomWaveforms_noIntegration

Module: iqm.pulse.gates.measure

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

Bases: CustomIQWaveforms

Base class for implementing a probe line probe pulse with custom waveforms in the I and Q channels without any integration.

Similar to the ProbePulse_CustomWaveforms except that signal integration is removed.

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

duration_in_seconds	Duration of the Schedule of the gate implementation (in seconds).
get_locus_mapping_name	Get the name of the locus mapping stored in ScheduleBuilder.ChipTopology for this implementation.
probe_timebox	Returns a "naked" probe timebox that supports convenient multiplexing through MultiplexedProbeTimeBox.__add__.

Parameters:

• parent (QuantumOp)

• name (str)

• locus (Locus)

• calibration_data (OILCalibrationData)

• builder (ScheduleBuilder)

root_parameters: dict[str, Parameter | Setting] = {'amplitude_i': Parameter(name='', label='Readout channel I amplitude', unit='', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'amplitude_q': Parameter(name='', label='Readout channel Q amplitude', unit='', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'duration': Parameter(name='', label='Readout pulse duration', unit='s', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'frequency': Parameter(name='', label='Readout pulse frequency', unit='Hz', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None), 'phase': Parameter(name='', label='Readout pulse phase', unit='rad', 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.

probe_timebox(key='', feedback_key='', do_acquisition=False)

Returns a “naked” probe timebox that supports convenient multiplexing through MultiplexedProbeTimeBox.__add__.

This method can be used if the user wants to control the multiplexing explicitly. With two MultiplexedProbeTimeBox``es ``A and B the result A + B has all the ReadoutTrigger instructions on each probe channel of A and B multiplexed together and played simultaneously.

Parameters:

• key (str) – The readout results generated on this trigger will be assigned to f"{qubit}__{key}", where qubit goes over the component names in self.locus. If empty, the key “readout.result” will be used to maintain backwards compatibility.

• feedback_key (str) – The signals generated by this measure operation are routed using this key for fast feedback purposes. See __call__().

• do_acquisition (bool) – if False, no acquisitions are added.

Returns:

MultiplexedProbeTimeBox containing the ReadoutTrigger instruction.

Return type:

TimeBox

duration_in_seconds()

Duration of the Schedule of the gate implementation (in seconds).

Can be left unimplemented if the duration e.g. depends on the gate arguments. Subclasses can reimplement this method in case it makes sense in their context.

Return type:

float

classmethod get_locus_mapping_name(operation_name, implementation_name)

Get the name of the locus mapping stored in ScheduleBuilder.ChipTopology for this implementation.

By default, it is "<operation_name>.<implementation_name>". Inheriting classes may override this for different behaviour.

Parameters:

• operation_name (str) – name of the quantum operation.

• implementation_name (str) – name of the implementation

Returns:

name of the locus mapping

Return type:

str

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.
