CouplerFluxPulseQubitACStarkPulseGate

Module: iqm.pulse.gates.cz

class iqm.pulse.gates.cz.CouplerFluxPulseQubitACStarkPulseGate(parent, name, locus, calibration_data, builder)

Bases: GateImplementation

Base class for CZ gates with coupler flux pulse and a qubit AC Stark pulse.

Analogous to the fast qubit flux pulse, the AC Stark pulse can tune the frequency of the qubit. Together with the coupler flux pulse, this can implement a fast qubit pulsed CZ gate.

Attributes

excluded_parameters	Parameters names to be excluded from self.parameters.
root_parameters
coupler_wave	Flux pulse Waveform to be played in the coupler flux AWG.
qubit_drive_wave	Qubit drive pulse waveform to be played in the qubit drive AWG.
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.

Parameters:

• parent (QuantumOp)

• name (str)

• locus (Locus)

• calibration_data (OILCalibrationData)

• builder (ScheduleBuilder)

coupler_wave: type[Waveform] | None

Flux pulse Waveform to be played in the coupler flux AWG.

qubit_drive_wave: type[Waveform] | None

Qubit drive pulse waveform to be played in the qubit drive AWG.

excluded_parameters: list[str] = []

Parameters names to be excluded from self.parameters. Inheriting classes may override this if certain parameters are not wanted in that class (also parameters defined by the waveforms can be excluded).

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
