Rigetti is a company specializing in superconducting quantum computers. Its core hardware operates within a dilution refrigerator, cooling the quantum processing unit (QPU) to millikelvin temperatures to maintain coherence. The official website emphasizes "Quantum. Quick." and claims that its 9-qubit QPU (Novera) is ready to ship immediately to help research teams quickly get started with quantum experiments and R&D. The core of their system consists of the superconducting QPU, dilution refrigerator, microwave signal chain, and measurement architecture. The company also publishes technical specifications for several of its processors (Ankaa-3), including qubit counts and gate fidelities, and continuously releases results from its quantum algorithm and system R&D.
Products / Services
▲ The Novera QPU. Rigetti's advanced quantum processing units (QPUs) share what is called the "Ankaa-class architecture," which is used in systems ranging from the large Ankaa systems to the 9-qubit R&D device.

Novera QPU (9 Qubits)
Positioning: A directly purchasable superconducting quantum processor, aimed at rapid deployment in research environments.
Status: Claimed to be "ready to ship today."
Cloud and Partner Access: Quantum Cloud Services (QCS) is Rigetti's "quantum-first" cloud computing platform. It uses the Quil SDK software tool, allowing users to write quantum programs in Quil and compile them for execution on simulators or on real quantum processors via QCS.
Deployed Quantum Processors: Rigetti's quantum processors are universal gate-model quantum computers based on tunable superconducting qubits. Ref

New research includes, for example, Coherent control using light: a microwave-to-optical quantum transducer with up to 1.18% conversion efficiency, which was used to demonstrate optically-driven Rabi oscillations of a superconducting qubit.
▲ Two optical fields (ω±) are coupled into the transducer via a waveguide. These two modes are resonant with the transducer's hybrid optical mode, which is generated by the capacitive coupling (CC) of a coupled paperclip resonator and a microwave LC resonator.
