Rigetti Computing is building the world’s most powerful computers to help solve humanity’s most pressing and important problems. These systems will perform computations that today’s fastest supercomputers are incapable of : unlocking entirely new classes of problems and offering a direct path to solutions. We are scientists, engineers, builders, and visionaries. We believe quantum computing is going to significantly affect health care, how we treat disease, how we generate energy, and how we feed humanity. Rigetti is the only company deploying full-stack solutions for hybrid classical/quantum computing. Our 19-qubit quantum computer is available online through our Forest platform, and the first commercially useful applications are already under exploration.
We were founded in 2013 by Chad Rigetti, and are located Berkeley and Fremont, California.
Key people at Rigetti Computing.
Rigetti Computing is a full-stack quantum computing company building superconducting quantum processors and integrated systems to power the next generation of quantum coherent supercomputing. Its mission is to accelerate the development of practical quantum computers by tightly integrating hardware, software, and cloud infrastructure, with the goal of achieving quantum advantage—where quantum systems outperform classical supercomputers on real-world problems. Rigetti focuses on scalable, high-fidelity superconducting qubits and has pioneered multi-chip quantum processors using a chiplet-based architecture, enabling modular scaling while improving yield and control.
The company serves enterprise, government, and research clients through its Rigetti Quantum Cloud Services platform and on-premises quantum systems, targeting applications in optimization, materials science, and machine learning. A key differentiator is its quantum-classical hybrid approach, including innovations like quantum preconditioning that enhance classical solvers with quantum assistance. Rigetti’s growth momentum is reflected in its roadmap: from its 36-qubit multi-chip Cepheus-1-36Q system to a planned 100+ qubit system with 99.5% fidelity by late 2025, positioning it as a leader in the race toward fault-tolerant, quantum-coherent supercomputing.

Rigetti Computing was founded in 2013 by Chad Rigetti, a former researcher at IBM and Yale with deep expertise in superconducting qubits and quantum information. The idea emerged from Rigetti’s conviction that quantum computing would require tight vertical integration—designing chips, control systems, and software in-house—to overcome the noise and scalability challenges that plagued early quantum hardware. Starting in Berkeley, California, the company quickly advanced from a three-qubit processor in 2016 to cloud-accessible quantum systems by 2017, launching its Forest platform to give developers access to real quantum hardware and simulators.
Early traction came from partnerships with national labs, academic institutions, and enterprise clients, validating its full-stack model. Rigetti raised significant venture capital, including rounds led by Andreessen Horowitz and Vy Capital, and in 2021 began selling on-premises quantum systems with qubit counts from 24 to 84. The company went public via SPAC in 2022, signaling its transition from a research-focused startup to a publicly traded player in the quantum race. Its in-house Fab-1 facility in Fremont, California, further solidified its control over the quantum stack, enabling rapid iteration on chip design and manufacturing.

Rigetti is riding the convergence of three major trends: the maturation of superconducting qubit technology, the growing demand for quantum-accelerated computing in optimization and simulation, and the push toward quantum-coherent supercomputing—where quantum processors act as co-processors tightly integrated with classical HPC infrastructure. The timing matters because classical computing is hitting physical and economic limits in areas like logistics, materials discovery, and financial modeling, creating a pull for quantum-enhanced solutions.
Market forces are aligning in Rigetti’s favor: governments and enterprises are increasing quantum R&D budgets, national labs are deploying on-premises systems, and cloud providers are expanding quantum offerings. Rigetti’s chiplet-based, modular architecture positions it well to scale faster than monolithic designs, while its quantum preconditioning work demonstrates a pragmatic path to utility in the NISQ era. By advancing both hardware and hybrid algorithms, Rigetti is helping define what quantum-coherent supercomputing looks like in practice—tight integration of quantum and classical resources to solve problems that are intractable today.

Rigetti is on a clear trajectory toward quantum advantage, targeting a 1,000+ qubit, 99.9% fidelity, error-corrected system within roughly 3–4 years. The next 12–24 months will be critical: delivering the 100+ qubit system with 99.5% fidelity, demonstrating meaningful quantum utility in optimization and simulation, and improving the economics of its chiplet-based manufacturing. Success here could solidify its position as a leader in superconducting quantum computing and make it a core component in future quantum-coherent supercomputing infrastructures.
Trends that will shape Rigetti’s journey include the race for fault tolerance, the evolution of quantum error correction, and the integration of quantum processors into classical HPC workflows. As quantum moves from lab curiosity to enterprise tool, Rigetti’s full-stack, hybrid approach gives it a strong edge in delivering practical value. Over time, its influence may extend beyond hardware to shaping standards in quantum-classical integration and quantum software stacks—making Rigetti not just a quantum computer builder, but a foundational player in the emerging era of quantum-coherent supercomputing.
