Core Technology

Rigetti's quantum computers are based on superconducting qubits, which are widely believed to be the leading qubit modality given their maturity, clear path to scaling, and fast gate speeds. Current Rigetti quantum computing systems achieve gate speeds of 50-70ns, which is about 1,000 times faster than other modalities such as ion traps and neutral atoms. Rigetti developed the industry's first multi-chip quantum processor for scalable quantum computing systems. Leveraging this proprietary technology, Rigetti deployed the industry's largest multi-chip quantum computer in 2025 with Cepheus-1-36Q, based on four 9-qubit chiplets tiled together. The company's distinctive chiplet-based architecture represents a fundamental departure from monolithic designs, enabling modular scaling by assembling quantum processors from smaller, interconnected components. This approach provides a practical pathway to building increasingly complex systems while maintaining performance standards. The Company designs and manufactures its chips in-house at Fab-1, the industry's first dedicated and integrated quantum device manufacturing facility. This vertical integration gives Rigetti unprecedented control over the entire quantum stack, from chip fabrication through system deployment and cloud delivery.

Competitive Advantage

Unlike monolithic designs, this architecture assembles quantum processors from smaller, interconnected 'chiplets,' offering a pathway to building increasingly complex and powerful systems. Rigetti's success in deploying the industry's largest multi-chip quantum computer in 2025, based on four 9-qubit chiplets tiled together, demonstrates the viability of this approach. Rigetti's core competitive advantage lies in its proprietary chiplet-based modular architecture, which provides superior scalability compared to traditional monolithic quantum processors. The Company's proprietary quantum-classical infrastructure provides high-performance integration with public and private clouds for practical quantum computing. The company's full-stack approach, combining in-house chip manufacturing, system integration, and cloud delivery through the Rigetti Quantum Cloud Services platform, creates multiple competitive moats. Additionally, Rigetti's achievement of gate speeds 1,000 times faster than competing modalities like ion traps provides significant computational advantages for time-sensitive quantum algorithms.

Challenges

Despite recent technical achievements, Rigetti faces significant challenges in scaling quantum systems while maintaining high fidelity rates. Building higher qubit count systems can uncover new challenges. We encountered complexities with our tunable couplers and have decided to run another iteration of our chip to further optimize the system and improve fidelity. During system testing, the Company identified tunable-coupler interactions between qubits that arise at higher qubit counts. These engineering complexities become more pronounced as systems scale beyond current capabilities. The quantum computing market remains highly competitive with well-funded rivals like IBM, Google, and Microsoft pursuing different technological approaches. Commercial viability remains a key challenge, as quantum computing applications are still largely experimental, requiring continued investment in R&D while revenue generation remains limited in the near term.

🔮 Looking Ahead

Rigetti is positioned at a critical inflection point as quantum computing transitions from research to commercial applications. The company's roadmap targeting 150+ qubit systems by late 2026 and 1,000+ qubit systems by 2027, combined with recent achievements in gate fidelity approaching 99.9%, suggests Rigetti is making meaningful progress toward practical quantum advantage. Strategic partnerships with government agencies through DARPA and AFRL contracts, coupled with international expansion into the UK and India, demonstrate growing market validation. However, the path forward requires continued execution on technical milestones while competing against well-funded rivals. Success will ultimately depend on Rigetti's ability to maintain its technological edge in chiplet-based architectures while scaling production and proving commercial viability of quantum applications across target industries including pharmaceuticals, finance, and logistics optimization.
