B. Business Model and Services

Rigetti's business model is primarily focused on the design, development, and provision of quantum processing units (QPUs) and quantum computing as a service (QCaaS). The majority of its revenue comes from technology development contracts, with a longer-term vision of increasing revenues from QPU sales and recurring income generated from quantum computing systems delivered via the cloud. The Rigetti Quantum Cloud Services (QCS) platform directly offers users access to its quantum computing capabilities, as well as being integrated with major public cloud service providers.

Rigetti Quantum Processing Units

The organization's QPUs include state-of-the-art silicon-based chips that feature superconducting qubits, designed for rapid gate operation and efficient performance. The Novera™ QPU is the company’s first commercially available product, comprising a 9-qubit chip with tunable couplers for improved two-qubit operations, and a 5-qubit chip for testing. Rigetti’s quantum processors are engineered at Fab-1, the company’s proprietary wafer fabrication facility, allowing for rapid prototyping and development cycles.

Quantum Computing as a Service

Rigetti provides access to its quantum computers via its QCaaS model, which facilitates outreach to a diverse client base without the operational complications associated with traditional computer hardware management. This service offers significant reductions in overhead costs for high-performance quantum computing needs, even extending to hybrid quantum-classical computing environments.

C. Technology Development

Rigetti Computing has developed key technologies that form the foundation of its quantum processing capabilities. The company has made strides in gate fidelity, speed, and scalability—crucial factors for practical quantum computing. Its proprietary modular chip architecture allows for the assembly of multiple quantum processor chips, promoting both scalability and performance.

Superconducting Quantum Processors

The utilization of superconducting qubits positions Rigetti at the forefront of quantum technology, as this method allows for fast gate speeds and a clear pathway to scaling. The latest achievements include the Cepheus-1-36Q system, which features a modular design capable of combining multiple chiplets, showcasing the company's commitment to reducing error rates and enhancing performance.

Innovations in Computing Speed and Fidelity

Rigetti's quantum computers have demonstrated substantial improvements in gate speed and fidelity over time. The company reported achieving a median two-qubit gate fidelity of 99.6% with its Cepheus-1-36Q system and gate times averaging 76 nanoseconds. These advancements highlight Rigetti's ongoing drive to enhance computational performance through innovations in quantum architecture and manufacturing processes.

D. Research and Development

Rigetti maintains a robust commitment to research and development, with a specialized team composed of experts across various facets of quantum technology. The company’s Fab-1 facility supports this endeavor by enabling iterative design and testing cycles that are considerably shorter than those typical within the semiconductor industry.

Key Partnerships

The company has established strategic partnerships with a range of organizations across multiple sectors, including academia, government, and commercial enterprises. Its collaborators include Amazon Web Services, Standard Chartered Bank, and various U.S. government agencies such as DARPA and the Department of Energy. These partnerships are essential for driving forward key technologies and applications in quantum computing.

E. Market Opportunity

The demand for enhanced computational power has surged, driven by the growing need for solutions to complex problems across industries such as finance, healthcare, logistics, and energy. Rigetti foresees a sequential growth in market demand for its quantum computing solutions, directly correlating with advancements in the capabilities of its systems.

Quantum Advantage

Achieving "Quantum Advantage," a term defined by the point where quantum computers can solve problems beyond the reach of classical systems, remains a primary goal for Rigetti. The company asserts that systems with over 1,000 qubits, coupled with high fidelity and speed, are necessary to reach this pivotal milestone, which could unlock a variety of expansive applications across different fields.

Anticipated Maturation Phases

The evolution of quantum computing is expected to progress through several maturity stages, ultimately leading to large-scale fault-tolerant quantum computing (LFTQC). Rigetti’s multi-chip architecture is believed to establish a pathway to achieving these future capabilities.
