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

device_element = BasicSpinElement("q1")

device_element.rxy.amp180 = 0.1
device_element.measure.pulse_amp = 0.25
device_element.measure.pulse_duration = 300e-9
device_element.measure.acq_delay = 430e-9
device_element.measure.integration_time = 1e-6
...

_generate_config() → dict[str, dict[str, qblox_scheduler.backends.graph_compilation.OperationCompilationConfig]][source]#

Generate part of the device configuration specific to a single qubit trapped in a quantum dot. A resonator to perform dispersive readout is attached to the gate to perform charge sensing.

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

generate_device_config() → qblox_scheduler.backends.graph_compilation.DeviceCompilationConfig[source]#

Generate a valid device config.

The config will be used for the qblox-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.

class ChargeSensor(/, name, **data: Any)[source]#

Bases: qblox_scheduler.device_under_test.device_element.DeviceElement

A device element representing a Charge Sensor connected to a tank circuit to perform dispersive readout.

Examples

Sensor parameters can be set through submodule attributes

from qblox_scheduler import ChargeSensor

sensor = ChargeSensor("s1")

sensor.measure.pulse_amp = 0.25
sensor.measure.pulse_duration = 300e-9
sensor.measure.acq_delay = 430e-9
