class BasicAerJob(backend, job_id, fn, qobj)

BasicAerJob class.

_executor

executor to handle asynchronous jobs

Type

futures.Executor

매개변수

• backend – the backend used to run the job.

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

__init__(backend, job_id, fn, qobj)

Initializes the asynchronous job.

매개변수

• backend – the backend used to run the job.

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

Methods

__init__(backend, job_id, fn, qobj)	Initializes the asynchronous job.
backend()	Return the instance of the backend used for this job.
cancel()	Attempt to cancel the job.
cancelled()	Return whether the job has been cancelled.
done()	Return whether the job has successfully run.
in_final_state()	Return whether the job is in a final job state.
job_id()	Return a unique id identifying the job.
qobj()	Return the Qobj submitted for this job.
result([timeout])	Get job result.
running()	Return whether the job is actively running.
status()	Gets the status of the job by querying the Python’s future
submit()	Submit the job to the backend for execution.
wait_for_final_state([timeout, wait, callback])	Poll the job status until it progresses to a final state such as DONE or ERROR.

backend()

Return the instance of the backend used for this job.

cancel()

Attempt to cancel the job.

cancelled()

Return whether the job has been cancelled.

반환 형식

bool

done()

Return whether the job has successfully run.

반환 형식

bool

in_final_state()

Return whether the job is in a final job state.

반환 형식

bool

job_id()

Return a unique id identifying the job.

반환 형식

str

qobj()

Return the Qobj submitted for this job.

반환값

the Qobj submitted for this job.

반환 형식

Qobj

result(timeout=None)

Get job result. The behavior is the same as the underlying concurrent Future objects,

https://docs.python.org/3/library/concurrent.futures.html#future-objects

매개변수

timeout (float) – number of seconds to wait for results.

반환값

Result object

반환 형식

qiskit.Result

예외

• concurrent.futures.TimeoutError – if timeout occurred.

• concurrent.futures.CancelledError – if job cancelled before completed.

running()

Return whether the job is actively running.

반환 형식

bool

status()

Gets the status of the job by querying the Python’s future

반환값

The current JobStatus

반환 형식

qiskit.providers.JobStatus

예외

• JobError – If the future is in unexpected state

• concurrent.futures.TimeoutError – if timeout occurred.

submit()

Submit the job to the backend for execution.

예외

• QobjValidationError – if the JSON serialization of the Qobj passed

• during construction does not validate against the Qobj schema. –

• JobError – if trying to re-submit the job.

wait_for_final_state(timeout=None, wait=5, callback=None)

Poll the job status until it progresses to a final state such as DONE or ERROR.

매개변수

• timeout (Optional[float]) – Seconds to wait for the job. If None, wait indefinitely.

• wait (float) – Seconds between queries.

• callback (Optional[Callable]) –

  Callback function invoked after each query. The following positional arguments are provided to the callback function:

  • job_id: Job ID

  • job_status: Status of the job from the last query

  • job: This BaseJob instance

  Note: different subclass might provide different arguments to the callback function.

예외

JobTimeoutError – If the job does not reach a final state before the specified timeout.
