Rigetti vs D-Wave: Which Quantum Computing Stock Holds More Promise?

Rigetti (RGTI) and D-Wave (QBTS) employ distinct quantum computing strategies: Rigetti targets universal, gate-based systems with superconducting qubits, while D-Wave focuses on quantum annealing for immediate enterprise optimization. D-Wave projects 181.5% sales growth for 2025 and has seen significant YTD stock gains, contrasting with Rigetti's projected 19.65% sales decline, yet Rigetti holds stronger growth and momentum scores due to technical advancements and a $250M partnership. Both are Zacks #3 (Hold), with Rigetti positioned for long-term potential in the quantum race, despite D-Wave's current commercial traction.

Analysis

Rigetti (RGTI) and D-Wave (QBTS) represent a fundamental strategic divergence in the quantum computing sector. Rigetti is pursuing the development of universal, gate-based quantum machines using a modular superconducting chiplet architecture. A key technical milestone is its Cepheus-1-36Q system, which has reportedly halved two-qubit error rates and achieved a median gate fidelity of approximately 99.5%, signaling progress toward scalable, higher-quality hardware. In contrast, D-Wave focuses on the more immediate commercialization of quantum annealing with its sixth-generation Advantage2 system, targeting enterprise optimization problems and securing paying customers today. This strategic split is mirrored in their financial outlooks and go-to-market models. D-Wave projects extraordinary year-over-year sales growth of 181.5% for 2025, driven by its enterprise adoption strategy. Conversely, Rigetti's sales are estimated to decline by 19.65% in the same period, reflecting its reliance on lumpy government contracts, such as a recent $5.8 million award from the U.S. Air Force. Despite the starkly different revenue trajectories, both companies are projected to narrow their losses per share significantly. Investor sentiment, as reflected by Zacks scores, appears to favor Rigetti's long-term potential; RGTI holds a strong 'A' Momentum score, supported by its technical roadmap and a $250 million scaling partnership, whereas QBTS has a 'D' Momentum score despite its 213.5% year-to-date stock surge and near-term revenue growth. Both stocks carry a Zacks Rank #3 (Hold) and an 'F' for Value, indicating that the market has priced in significant future potential for this speculative sector.

Key Decisions for Investors

• Investors must choose between Rigetti's long-term, high-risk play on universal quantum computing, which is supported by technical momentum, and D-Wave's near-term commercial strategy focused on the niche quantum annealing market.
• For Rigetti (RGTI), monitor the achievement of its roadmap milestones, particularly the delivery of a 100+ qubit system by year-end 2025, as its valuation is heavily dependent on future technical execution rather than current financials, which show a projected revenue decline.
• For D-Wave (QBTS), focus on its ability to convert enterprise pilot programs into significant, recurring revenue streams, as this is critical to justifying its strategy against a backdrop of weaker growth and momentum scores compared to RGTI.
• Given that both stocks are rated 'Hold' and carry premium valuations ('F' Value score), it may be prudent to await more definitive catalysts, such as sustained profitability or a clear technological advantage, before committing significant capital.
