  description: 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.

  description: 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.

  description: 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.
name: Rigetti Computing
description: 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.
