      REST API for submitting quantum circuits, managing jobs and sessions, inspecting backends and characterizations,
      and tracking cost and usage on the IonQ Quantum Cloud. Backends include the qpu.aria-1, qpu.aria-2, qpu.forte-1,
      qpu.forte-enterprise-1 trapped-ion QPUs and the IonQ noisy/ideal simulator (up to 29 qubits). Supports
      single-circuit, multi-circuit, native-gate, QAOA, and Quantum Function jobs. Authentication via Authorization
      header `apiKey $IONQ_API_KEY`.

      The previous-generation IonQ Quantum Cloud REST API (v0.3) for submitting and managing jobs, characterizations,
      backends, and reports. Superseded by v0.4 which adds Sessions, separated cost/results endpoints, and restructured
      characterizations. v0.3 remains supported for existing integrations.

  IonQ (NYSE IONQ) is a College Park, Maryland-based public trapped-ion quantum computing company. IonQ designs,
  manufactures, and operates trapped-ion quantum computers (Aria, Forte, Forte Enterprise, Tempo, Harmony) and delivers
  them through the IonQ Quantum Cloud REST API, on-premises Forte Enterprise systems, and partner clouds (AWS Braket,
  Microsoft Azure Quantum, Google Cloud). The platform supports submission of QIS and native-gate circuits,
  multi-circuit and Quantum Function jobs, reserved Sessions, error mitigation, and organization-level usage and cost
  reporting. IonQ's quantum networking, security (QKD), sensing, and space-infrastructure businesses extend the
  trapped-ion core into a broader quantum systems portfolio.
