Rigetti Computing Provides Update on 108-Qubit System
01/09/2026 08:00 AM • Rigetti Computing announced a delay in the general availability of its 108-qubit Cepheus-1-108Q quantum computing system to around the end of Q1 2026. The company cited the need for additional testing and optimization, particularly to address complexities with tunable couplers and achieve its 99.5% median two-qubit gate fidelity target. Despite the delay, Rigetti reported strong progress with current systems achieving 99% fidelity on the 108-qubit system, 99.7% on the 9-qubit system, and 99.6% on the 36-qubit system.
RGTI - While the company is delaying a major product launch, which is typically negative, the announcement demonstrates commitment to quality and performance standards. The company is making measurable progress on fidelity metrics and has a clear technical roadmap. The delay is framed as a strategic decision to optimize performance rather than a fundamental setback, and the company continues to operate existing systems successfully.
