  title: Google Quantum Engine Calibrations Jobs API
  version: v1alpha1
  description: 'REST surface of the Google Quantum Engine service (`quantum.googleapis.com`,

    `google.cloud.quantum.v1alpha1.QuantumEngineService`). The Quantum Engine

    accepts hardware-compatible quantum circuits as **programs**, executes them

    as **jobs** on Google''s superconducting **processors** (Willow- and

    Sycamore-class), manages **reservations** of processor time, and exposes

    processor **calibration** snapshots. The canonical client is the

    `cirq-google` Python package (`cirq_google.Engine`).


    Access is restricted: callers must use a Google Cloud project with the

    Quantum Engine API enabled, be on the approved-user list, and authenticate

    using Application Default Credentials (OAuth 2.0 with the

    `https://www.googleapis.com/auth/cloud-platform` scope).
