Rigetti Computing
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.

Rigetti Book QPU Reservation
Find an available reservation slot on a quantum processor, book it, and confirm the booking.
ARAZZORigetti Cancel Reservation
List a user's reservations, inspect the most relevant one, and cancel it, confirming the cancellation.
ARAZZORigetti Create Execution Engagement
Resolve a processor's default endpoint and create an engagement that grants credentialed access to execute on the QPU.
ARAZZORigetti Discover Quantum Processor
List available QPUs, then inspect one processor's metadata, instruction set architecture, and live accessors.
ARAZZORigetti Provision Endpoint and Engage
Create a private endpoint for a processor, poll until it reports healthy, then create an engagement against it.
ARAZZORigetti Reservation Readiness Check
Resolve the caller's identity and balance, read a processor's maintenance calendar, and surface available reservation slots before booking.
