class ExperimentFunctional(qubit: int)

Bases: qilisdk.functionals.functional.Functional, abc.ABC, Generic[TResult_co]

Abstract base class for single-qubit experiment functionals.

This class serves as a generic interface for defining quantum characterization experiments such as Rabi or T1. Each subclass specifies a concrete ExperimentResult type and the corresponding sweep parameters.

Initialize the experiment functional.

Paràmetres:

qubit (int) – The physical qubit index on which the experiment is performed.

property qubit: int

The physical qubit index on which the experiment is performed.

Retorna:

Index of the qubit.

Tipus de retorn:

int

class RabiExperiment(qubit: int, drive_duration_values: numpy.ndarray)

Bases: ExperimentFunctional[qilisdk.experiments.experiment_result.RabiExperimentResult]

Rabi experiment functional for a single qubit.

This functional defines a standard Rabi oscillation experiment where the drive pulse duration is swept to measure the oscillatory response of the qubit under continuous driving.

Initialize a Rabi experiment functional.

Paràmetres:

• qubit (int) – The physical qubit index on which the experiment is performed.

• drive_duration_values (np.ndarray) – Array of drive pulse durations (in nanoseconds) used to sweep the experiment.

Bases: ExperimentFunctional[qilisdk.experiments.experiment_result.T1ExperimentResult]

T1 relaxation experiment functional for a single qubit.

This functional defines a standard T1 (energy relaxation) experiment, where the delay between excitation and measurement is varied to extract the relaxation time constant of the qubit.

Initialize a T1 experiment functional.

Paràmetres:

• qubit (int) – The physical qubit index on which the experiment is performed.

Bases: ExperimentFunctional[qilisdk.experiments.experiment_result.T2ExperimentResult]

T2 dephasing experiment functional for a single qubit.

This functional defines a Ramsey/spin-echo style T2 experiment, where the free-evolution delay between phase-sensitive pulses is swept to extract the qubit coherence time.

Initialize a T2 dephasing experiment functional.
