JobV1

class qiskit.providers.JobV1(backend, job_id, **kwargs)

Bases : Job, ABC

Class to handle jobs

This first version of the Backend abstract class is written to be mostly backwards compatible with the legacy providers interface. This was done to ease the transition for users and provider maintainers to the new versioned providers. Expect, future versions of this abstract class to change the data model and interface.

Initializes the asynchronous job.

Paramètres:

• backend (Backend | None) – the backend used to run the job.

• job_id (str) – a unique id in the context of the backend used to run the job.

• kwargs – Any key value metadata to associate with this job.
