Rigetti Computing builds and operates superconducting quantum computers. The core product is Rigetti's quantum processing unit (QPU), a superconducting chip that uses quantum mechanical properties to process information in ways classical computers cannot. Current systems include the 84-qubit Ankaa-3 and the 36-qubit Cepheus-1-36Q, the latter built using Rigetti's proprietary "chiplet" architecture, which tiles multiple smaller chips together. Rigetti's target customers today are government agencies, national laboratories, and academic institutions — not commercial enterprises. Rigetti acknowledges it is still roughly 3–5 years from achieving "quantum advantage," the point at which quantum computers can outperform classical computers on commercially meaningful problems. Rigetti sells access to its systems via cloud (through its own QCS platform and via AWS and Microsoft Azure) and through direct on-premises hardware sales. Today, the majority of revenue comes from government-funded R&D contracts with organizations like DARPA, the U.S. Department of Energy, the UK's NQCC, and India's C-DAC. QPU and systems sales, cloud subscriptions, chip foundry services, and professional services round out the revenue mix. Rigetti owns and operates Fab-1, an in-house fabrication facility in Fremont, California, enabling vertical integration from chip design through cloud delivery. Rigetti's roadmap targets 1,000+ qubits by end of 2027 and quantum advantage by 2028–2029.
