laboneq_applications.experiments.iq_blobs

This module defines the IQ_blob experiment.

In this experiment, we perform single-shot measurements with the qubits prepared in the states g, e, and/or f.

The IQ blob experiment has the following pulse sequence:

qb --- [ prepare transition ] --- [ measure ]

IQBlobExperimentOptions

Options for the iq_blobs experiment.

The purpose of this class is to change the default value of averaging_mode in BaseExperimentOptions.

Attributes:

Name	Type	Description
averaging_mode	AveragingMode	Averaging mode used for the experiment Default: AveragingMode.SINGLE_SHOT

averaging_mode: AveragingMode = workflow.option_field(AveragingMode.SINGLE_SHOT, description='Averaging mode used for the experiment') class-attribute instance-attribute

IQBlobExperimentWorkflowOptions

Options for the iq_blobs experiment workflow.

Attributes:

Name	Type	Description
do_analysis	bool	Whether to run the analysis workflow. Default: True

do_analysis: bool = workflow.option_field(True, description='Whether to run the analysis workflow.') class-attribute instance-attribute

create_experiment(qpu, qubits, states, options=None)

Creates an IQ-blob Experiment.

Parameters:

Name	Type	Description	Default
qpu	QPU	The qpu consisting of the original qubits and quantum operations.	required
qubits	Qubits	The qubit to run the experiments on.	required
states	Sequence[str]	The basis states the qubits should be prepared in. May be either a string, e.g. "gef", or a list of letters, e.g. ["g","e","f"].	required
options	IQBlobExperimentOptions | None	The options for building the experiment as an in stance of [IQBlobExperimentOptions]. See the docstring of this class for more details.	None

Returns:

Name	Type	Description
experiment	Experiment	The generated LabOne Q experiment instance to be compiled and executed.

Example

options = IQBlobExperimentOptions()
options.count(10)
setup = DeviceSetup()
qpu = QPU(
    qubits=[TunableTransmonQubit("q0"), TunableTransmonQubit("q1")],
    quantum_operations=TunableTransmonOperations(),
)
temp_qubits = qpu.copy_qubits()
create_experiment(
    qpu=qpu,
    qubits=[temp_qubits[0],temp_qubits[1]],
    states="ge",
    options=options,
)

experiment_workflow(session, qpu, qubits, states, temporary_parameters=None, options=None)

The IQ-blob experiment Workflow.

The workflow consists of the following steps:

• create_experiment
• compile_experiment
• run_experiment
• analysis_workflow

Parameters:

Name	Type	Description	Default
session	Session	The connected session to use for running the experiment.	required
qpu	QPU	The qpu consisting of the original qubits and quantum operations.	required
qubits	Qubits	The qubits to run the experiments on.	required
states	Sequence[str]	The basis states the qubits should be prepared in. May be either a string, e.g. "gef", or a list of letters, e.g. ["g","e","f"].	required
temporary_parameters	dict[str, dict | TransmonParameters] | None	The temporary parameters to update the qubits with.	None
options	IQBlobExperimentWorkflowOptions | None	The options for building the workflow as an instance of [TuneUpWorkflowOptions]. See the docstring of this class for more details.	None

Returns:

Name	Type	Description
WorkflowBuilder	None	The builder for the experiment workflow.

Example

options = experiment_workflow.options()
options.count(10)
qpu = QPU(
    qubits=[TunableTransmonQubit("q0"), TunableTransmonQubit("q1")],
    quantum_operations=TunableTransmonOperations(),
)
temp_qubits = qpu.copy_qubits()
result = experiment_workflow(
    session=session,
    qpu=qpu,
    qubits=[temp_qubits[0],temp_qubits[1]],
    states="ge",
