Update on the 2026 leg. On 7 April 2026 Rigetti announced general availability of Cepheus-1-108Q, a 108-qubit system built from twelve interconnected 9-qubit chiplets, running at a 99.1% median two-qubit gate fidelity. That is the 100+ qubi

Update on the 2026 leg. On 7 April 2026 Rigetti announced general availability of Cepheus-1-108Q, a 108-qubit system built from twelve interconnected 9-qubit chiplets, running at a 99.1% median two-qubit gate fidelity. That is the 100+ qubit chiplet system the roadmap dated 2025, delivered about three months after the end of that year, so the earlier off-track reading stands. The next step on the roadmap is 150+ qubits in 2026; Rigetti says it will keep improving the system through 2026, and we are not scoring that step before its deadline. urn:symbiq:ledger:rigetti-roadmap-2025-2027:checkin:2026-09-23:1 2026-09-23T00:00:00Z 2026-09-23T00:00:00Z

The 2025 interim target, a 100+ qubit chiplet-based system, slipped. On 9 January 2026 Rigetti said it was revising its roadmap and that its 108-qubit Cepheus-1-108Q was "now expected to reach general availability around the end of the first quarter of 2026". Under this claim's criteria an interim slip still leaves PARTIALLY_VERIFIED open if the 2027 target is substantially met. urn:symbiq:ledger:rigetti-roadmap-2025-2027:checkin:2026-08-27:0 2026-08-27T00:00:00Z 2026-08-27T00:00:00Z

Captured at seed. Worth noting for context: Rigetti's public roadmap has moved before -- an earlier iteration of this same roadmap targeted 100+ qubits with 99.5% median two-qubit fidelity specifically "by the end of 2025," reported the same week -- so the 2025 leg of this claim is the nearest-term thing to watch first. urn:symbiq:ledger:rigetti-roadmap-2025-2027:tracked:2026-08-27:0 2026-08-27T00:00:00Z 2026-08-27T00:00:00Z

Claim captured, with its resolution criteria and the sources that will settle it. Resolves by 2027-12-31.

Resolves by 2027-12-31 (+30 day grace). Criteria: Resolves VERIFIED if Rigetti has, by 31 Dec 2027 (plus grace), shipped or operated a system matching each named year's qubit-count target within that year -- checked against Rigetti's own quarterly technical updates and independent reporting, not press-release qubit counts alone (this project's own recurring lesson: a qubit count without connectivity/fidelity context is close to meaningless -- see race.html). PARTIALLY_VERIFIED if the 2025/2026 interim targets slip but the 2027 endpoint is still substantially met. NOT_VERIFIED if the 2027 target is missed outright.
