      The Rigetti Quantum Cloud Services (QCS) HTTP API is the OpenAPI-specified REST surface for managing accounts,
      groups, users, billing, reservations, endpoints, engagements, and discovering quantum processor metadata including
      Instruction Set Architecture (ISA) and calibration. Authentication is OAuth2 (JWT bearer) issued via Okta. The API
      follows Google API Improvement Proposals (AIP) and is paired with a gRPC API for quantum program translation and
      controller execution against the QPU.

      gRPC Translation service that compiles native Quil programs into encrypted Controller Jobs for execution on a
      Rigetti QPU. Operations include TranslateQuilToEncryptedControllerJob and
      GetQuantumProcessorQuilCalibrationProgram. Authenticated with the same JWT bearer token used by the QCS HTTP API
      and consumed via qcs-sdk-rust/qcs-sdk-python or the Rust qcs-api-client-grpc crate.

      gRPC Controller service that executes encrypted Controller Jobs on a Rigetti QPU endpoint and returns measurement
      (readout) results. Operations include ExecuteControllerJob, BatchExecuteControllerJobs, GetControllerJobResults,
      CancelControllerJobs, and GetControllerJobStatus. Used through qcs-sdk-rust / qcs-sdk-python after obtaining a
      CreateEngagement token from the QCS HTTP API.

  Rigetti Computing (Nasdaq, RGTI) is a Berkeley, California-based quantum computing company building superconducting
  quantum processors and the full-stack software needed to program and operate them. Founded in 2013 by Chad Rigetti,
  the company designs, manufactures, and operates multi-chip superconducting QPUs at its Fab-1 in Fremont, CA and offers
  cloud-based access through Quantum Cloud Services (QCS). Rigetti also sells the Novera QPU (9-qubit) for on-premises
  customers and provides Quantum Foundry Services for custom development. The current generation system Cepheus-1-108Q
  (107 qubits, deployed April 2026) is accessed via a hybrid REST + gRPC API surface, programmed using the open Quil
  instruction language, the pyQuil Python library, and the multi-language qcs-sdk (Rust core with Python bindings).
  Rigetti's hardware is also available indirectly through AWS Braket, Microsoft Azure Quantum, and as a Qiskit provider
  via qiskit-rigetti.
