Rigetti Computing has announced a significant update to its development schedule, opting to delay the broader release of its next-generation quantum processor. The company’s new 108-qubit system, named Cepheus™‑1‑108Q, will now target general availability by the end of the first quarter of 2026, a shift from its earlier launch plan. This decision underscores a strategic pivot: emphasizing quality and precision over speed, even as the move may draw near-term skepticism from some market observers.
A Deeper Dive into the Schedule Change
On January 9, Rigetti formally updated its technology roadmap, pushing back the introduction timeline for its largest modular quantum processor to date. The delay is attributed to requirements for additional testing and optimization. Company leadership acknowledged meaningful progress but stated that internal quality benchmarks have not yet been fully met.
A primary technical challenge involves the complexity of “tunable couplers,” essential components that manage interactions between qubits. To address this, Rigetti has initiated another chip iteration cycle. The objective is to enhance overall system performance, with a specific focus on reducing error rates in two-qubit operations.
Performance Metrics Take Precedence
From a technical standpoint, Rigetti reports tangible advances. The current iteration of the 108-qubit system demonstrates a median two-qubit gate fidelity of 99%. However, the company’s internal target is more ambitious, aiming to elevate this figure to 99.5% before commercial release.
The firm’s capability is evidenced by its smaller-scale systems. Its 9-qubit processor achieves a median two-qubit fidelity of 99.7%, while the 36-qubit system reaches 99.6%. These results confirm the underlying technology’s potential; the core hurdle is replicating this high performance consistently on the much larger 108-qubit architecture.
Some market analysts view the revised schedule as a manageable setback. For instance, Wedbush Securities reaffirmed its “Outperform” rating on Rigetti shares on January 12, emphasizing that in the quantum computing sector, precision should rightly take precedence over a rushed launch.

Industry Challenges and Investor Sentiment
This roadmap adjustment highlights the inherent execution risks within the quantum industry. Scaling systems to higher qubit counts does not present a linear increase in complexity—technical hurdles, like those with the tunable couplers, can disrupt entire project timelines.
Rigetti’s 108-qubit machine is itself an intermediate step toward a more ambitious long-term goal: developing a system with over 1,000 qubits by 2027. As these targets become more advanced, the credibility of each milestone grows in importance.
A fundamental challenge remains: converting technical achievements into predictable revenue streams. Rigetti is not yet profitable, leading investors to scrutinize whether technological progress will translate into a sustainable business model.
Market sentiment is further contextualized by a report dated January 14, which noted net insider selling across several quantum computing stocks over the past three years, including Rigetti. Such activity fuels debate over whether current valuations appropriately reflect future potential or have run ahead of reality.
The stock’s price action reflects this blend of opportunity and uncertainty, exhibiting considerable volatility. While recently trading at $24.47—approximately 22% above its level from 30 days prior—the equity remains notably below its 52-week high.
Key Upcoming Milestones for Shareholders
Two forthcoming dates are particularly critical for investor assessment. The first is the end of Q1 2026, the new target for the Cepheus‑1‑108Q system’s general availability. This will serve as a practical test of the updated roadmap. The second is the next quarterly earnings report, anticipated between March 6 and 12, 2026. Management is expected to provide greater detail on how the revised timeline impacts revenue projections, cost structure, and the long-term plan for systems exceeding 1,000 qubits.
