Rigetti Computing Announces Update on 108-Qubit Quantum Computing System

BERKELEY, Calif., Jan. 9, 2026 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI), a leader in full-stack quantum-classical computing, has announced revisions to its development roadmap regarding the upcoming 108-qubit quantum computing system, known as Cepheus™-1-108Q. The company now anticipates that this system will reach general availability by the end of the first quarter of 2026.

Details on Cepheus-1-108Q Development

Rigetti Computing's CEO, Dr. Subodh Kulkarni, emphasized the significance of the extended timeline: “While we are making strong progress with Cepheus-1-108Q, we are taking more time to test and optimize the system to ensure the performance is up to our standards.” The delay is primarily attributed to complexities encountered during the development process, particularly related to the system’s tunable couplers.

Rigetti is keen on maintaining high standards for the system, aiming for a median two-qubit gate fidelity rate of 99.5%. Currently, the company has achieved a median two-qubit gate fidelity rate of 99% on the 108-qubit system, 99.7% on its 9-qubit system, and 99.6% on its 36-qubit system.

Technical Specifications and Architecture

The Cepheus-1-108Q system is constructed using twelve 9-qubit chiplets, taking advantage of Rigetti’s proprietary modular chip architecture. This makes it the highest qubit count system the company will release, setting the stage for it to be the largest modular quantum computing system in the industry.

Commitment to Quantum Computing

Rigetti Computing is dedicated to leading advancements in the field of quantum computing. The company’s quantum systems are built on superconducting qubits, recognized as an optimal choice due to their scalability, maturity, and fast gate speeds. Current systems boast gate speeds ranging from 50-70ns, which is approximately 1,000 times faster than other quantum computing modalities, such as ion traps and neutral atoms.

Global Impact and Future Outlook

Through its Rigetti Quantum Cloud Services (QCS) platform, the company enables enterprises, governmental entities, and academic institutions globally to engage in groundbreaking research and development. By providing high-performance integration with both public and private clouds, Rigetti enhances the practical applications of quantum computing.

In addition to its cloud services, Rigetti also sells on-premises quantum computing systems ranging from 9 to 108 qubits to support national laboratories and quantum computing centers. The innovative 9-qubit Novera QPU is specifically designed to integrate seamlessly with existing cryogenic and control infrastructure.

Upcoming Innovations and Manufacturing

Building on previous successes, Rigetti developed the first multi-chip quantum processor aimed at scalability, deploying the largest multi-chip quantum computer in 2025 with the Cepheus-1-36Q system. The company prides itself on its in-house manufacturing capabilities at Fab-1, the industry’s first dedicated quantum device manufacturing facility.
