RestlessMixin

class RestlessMixin

A mixin to facilitate restless experiments.

This class defines the following methods:

• enable_restless()

• _get_restless_processor()

• _t1_check()

A restless enabled experiment is an experiment that can be run in a restless measurement setting. In restless measurements, the qubit is not reset after each measurement. Instead, the outcome of the previous quantum non-demolition measurement is the initial state for the current circuit. Restless measurements therefore require special data processing which is provided by sub-classes of the RestlessNode. Restless experiments are a fast alternative for several calibration and characterization tasks, for details see https://arxiv.org/pdf/2202.06981.pdf.

This class makes it possible for users to enter a restless run mode without having to manually set all the required run options and the data processor. The required options are rep_delay, init_qubits, memory, and meas_level. Furthermore, subclasses can override the _get_restless_processor() method if they require more complex restless data processing such as two-qubit calibrations. In addition, this class makes it easy to determine if restless measurements are supported for a given experiment.

Methods

RestlessMixin.enable_restless([rep_delay, ...])

Enables a restless experiment by setting the restless run options and the restless data processor.
