class PortsSpin(parent: qcodes.instrument.base.InstrumentBase, name: str, *, microwave: str | None = None, gate: str | None = None, readout: str | None = None)

Bases: qcodes.instrument.InstrumentChannel

Submodule containing the ports.

microwave

Name of the element’s microwave port.

gate

Name of the element’s ohmic gate port.

readout

Name of the element’s readout port.

class ClocksFrequenciesSpin(parent: qcodes.instrument.base.InstrumentBase, name: str, *, f_larmor: float = math.nan, readout: float = math.nan)

Bases: qcodes.instrument.InstrumentChannel

Submodule containing the clock frequencies specifying the transitions to address.

f_larmor

Larmor frequency for the spin qubit

readout

Frequency of the ro clock.

class RxyGaussian(parent: qcodes.instrument.base.InstrumentBase, name: str, *, amp180: float = math.nan, duration: float = 2e-08, reference_magnitude_dBm: float = math.nan, reference_magnitude_V: float = math.nan, reference_magnitude_A: float = math.nan)

Bases: qcodes.instrument.InstrumentChannel

Submodule containing parameters for performing an Rxy operation.

The Rxy operation uses a Gaussian pulse.

amp180

Amplitude required to perform a $pi$ pulse.

duration

Duration of the control pulse.

class DispersiveMeasurementSpin(parent: qcodes.instrument.base.InstrumentBase, name: str, *, gate_pulse_amp: float = 0, **kwargs)

Bases: quantify_scheduler.device_under_test.transmon_element.DispersiveMeasurement

Submodule containing parameters to perform a measurement.

The measurement that is performed is using dispersive_measurement_spin().

gate_pulse_amp

Amplitude of the gate pulse.

class BasicSpinElement(name: str, **kwargs: Any)

Bases: quantify_scheduler.device_under_test.device_element.DeviceElement

A device element representing a Loss–DiVincenzo Spin qubit. The element refers to the intrinsic spin-1/2 degree of freedom of individual electrons/holes trapped in quantum dots. The charge of the particle is coupled to a resonator.

Examples

Qubit parameters can be set through submodule attributes

from quantify_scheduler import BasicSpinElement

qubit = BasicSpinElement("q1")

qubit.rxy.amp180(0.1)
qubit.measure.pulse_amp(0.25)
qubit.measure.pulse_duration(300e-9)
qubit.measure.acq_delay(430e-9)
qubit.measure.integration_time(1e-6)
...

reset: quantify_scheduler.device_under_test.transmon_element.IdlingReset

Submodule IdlingReset.

rxy: RxyGaussian

Submodule RxyGaussian.

measure: DispersiveMeasurementSpin

Submodule DispersiveMeasurementSpin.

pulse_compensation: quantify_scheduler.device_under_test.transmon_element.PulseCompensationModule

clock_freqs: ClocksFrequenciesSpin

Submodule ClocksFrequenciesSpin.

_generate_config() → dict[str, dict[str, quantify_scheduler.backends.graph_compilation.OperationCompilationConfig]]

Generate part of the device configuration specific to a single qubit.

This method is intended to be used when this object is part of a device object containing multiple elements.

generate_device_config() → quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig

Generate a valid device config.

The config will be used for the quantify-scheduler making use of the compile_circuit_to_device_with_config_validation() function.

This enables the settings of this qubit to be used in isolation.
