  description: 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`.

  description: 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 Superseded by v0.4 which adds Sessions, separated cost/results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.

description: 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.
