  title: IBM Quantum Submit Job and Poll Results
  summary: Submit a Qiskit Runtime primitive job, poll until it reaches a terminal state, and fetch the final result.
  description: >-
    The canonical end-to-end Qiskit Runtime execution flow. The workflow first
    confirms the target backend is online and reports its queue depth, then
    invokes a Sampler or Estimator primitive with the supplied program id and
    PUBs, polls the job status until it reaches a terminal Completed, Failed, or
    Cancelled state, and finally retrieves the job's result payload. Every step
    spells out its request inline — including the bearer token, Service-CRN, and
    IBM-API-Version headers — so the flow can be read and executed without
    opening the underlying OpenAPI descriptions.
