Roadmap Target

Lyra (336 qubits, late 2026 narrow advantage target); 1,000+ qubits by end of 2027; utility-scale ~2027–2029

Cepheus-1-108Q uses a modular 12×9-qubit chiplet architecture and became generally available in April 2026. Rigetti's Q2 2026 results reported approximately 99.9% median 1Q fidelity, approximately 99.1% median 2Q fidelity and approximately 60 ns gate speed; the live system count remained 107 active at the last verification. Ankaa-3 (84Q) was the prior GA system.

Competing Approaches

Big tech companies using the same Superconducting approach

Superconducting

Willow (105 qubits) achieved below-threshold error correction (Dec 2024); first verifiable quantum advantage via the Quantum Echoes (OTOC) algorithm — 13,000× faster than the top classical supercomputer, published in Nature (Oct 2025); expanded into neutral-atom quantum computing (Mar 2026); reinforcement-learning calibration improved logical stability 3.5× and reduced surface-code quantum-memory errors below one per 1,000 cycles (Jul 2026)

Useful quantum computing beyond classical simulation by 2029

qubits

Nighthawk r2 (Aug 2026) combines 120 programmable qubits, 218 couplers and 120 independent reset elements; it executes 100,000+ circuits per second, up to 25× Heron throughput, and delivered accurate results on circuits with 7,500+ gates, achieving IBM's 2026 roadmap milestone. Experimental Loon (112 qubits) demonstrates fault-tolerant hardware building blocks; IBM completed its acquisition of HRL Laboratories in Aug 2026.

First examples of quantum advantage in 2026; fault-tolerant Starling (200 logical qubits, 100 million gates) in 2029; Blue Jay (2,000 logical qubits, 1 billion gates) by 2033+

Financial Story

FY 2025

Rigetti FY2025: Revenue grows YoY amid continued deep losses; $250M Quanta partnership anchors scale-up strategy

·Quanta Computer Collaboration Agreement signed Feb 2025: each party commits $250M+ over 5 years; Quanta also purchased ~$35M of common stock at ~$11.59/share in April 2025.
·Received $8.4M purchase order from India's C-DAC (Jan 2026) to deliver a 108-qubit quantum computer, with deployment expected H2 2026.
·Launched 36-qubit Cepheus-1-36Q multi-chip system in Q2 2025, achieving 99.6% median two-qubit gate fidelity — halving error rate vs. prior Ankaa-3 system.

FY 2024

Rigetti Computing burns cash in FY2024 while launching 84-qubit Ankaa-3 and securing Quanta deal

·Launched 84-qubit Ankaa-3 system in Q4 2024, halving two-qubit gate error rates to achieve 99.0% median iSWAP fidelity.
·Signed Collaboration Agreement with Quanta Computer in Feb 2025; Quanta to invest $250M+ over 5 years and purchase ~$35M of RGTI stock via private placement.
·Revenue primarily derived from government/public-sector technology development contracts; began QPU hardware sales in 2023.

Plans to release a 36-qubit modular system by mid-2025 (targeting 2x error rate reduction) and a 100+ qubit system by end of 2025. Quanta collaboration expected to fund component development. Additional capital raises likely required.

FY 2023

Rigetti Computing burns cash in quantum R&D push; runway extends only to mid-2025

·Launched 84-qubit Ankaa-2 system achieving 98% median 2-qubit fidelity (2.5x improvement over prior QPUs) and introduced Novera QPU, first commercially available 9-qubit product.
·Made first-ever QPU hardware sales in 2023, delivering 9-qubit systems to Fermilab and a national laboratory; expanding revenue model beyond cloud services.
·Secured multiple government contracts including DARPA IMPAQT and DARPA Quantum Benchmarking Phase 2; Innovate UK grant awarded post-period for 24-qubit system delivery.

Company targets 99% 2-qubit gate fidelity on Ankaa-3 (84-qubit) by end of 2024, then plans to scale to a 336-qubit Lyra system; near-term survival contingent on raising additional capital before early Q3 2025.

FY 2022

Rigetti Computing posts widening losses in FY2022 as quantum startup burns cash post-SPAC merger

·Completed Business Combination (SPAC merger) in March 2022, converting to public company on Nasdaq under ticker RGTI with warrants trading as RGTW.
·Revenue mix currently dominated by government/research development contracts; longer-term model targets recurring QCaaS cloud revenue from quantum computing access.
·Deployed Ankaa-1 84-qubit system internally for testing in March 2023; roadmap targets 336-qubit Lyra system contingent on achieving ≥99% gate fidelity milestones.

Management expects continued operating losses for the foreseeable future. Near-term focus is on refining Ankaa-1 84-qubit system performance, targeting external customer launch, then scaling to Ankaa-2 and eventually the 336-qubit Lyra system. Additional capital raise anticipated by late 2024/early 2025.

Supernova II SPAC posts $23.2M net loss in FY2021; Rigetti merger pending with $147.5M PIPE

·Signed merger agreement with Rigetti Computing (quantum computing); PIPE of ~$147.5M committed ($102.5M initial + $45M subsequent) at $10.00–$10.25/share.
·$345M raised in March 2021 IPO (34.5M units at $10.00) placed in trust; no operating revenue generated as SPAC has not yet completed a business combination.
·Material weakness identified in internal controls over accounting for complex financial instruments (warrants), triggering restatement of Q1 and Q2 2021 financials.

Completion of the Rigetti business combination is targeted; if not consummated by March 4, 2023, the SPAC must liquidate and redeem public shares at trust value (~$10.00/share). No operating revenue until deal closes.

The company, in consultation with auditor Marcum LLP and its Audit Committee, restated the affected financials in its Q3 2021 Form 10-Q filed November 15, 2021, with no expected impact on cash or trust account balances. Management acknowledged a material weakness in internal controls and that disclosure controls were ineffective as a result of the classification error.↗
