RGTI vs QBTS: A Detailed Look at Two Quantum Computing Stocks

Rigetti Computing (RGTI) and D-Wave Quantum (QBTS) are drawing strong investor attention as quantum computing becomes one of the most watched technology themes in 2026.

The Zacks report highlights a clear split: D-Wave appears stronger in near-term commercial traction, while Rigetti offers longer-term upside tied to gate-model quantum breakthroughs. D-Wave has benefited from record bookings and expanding system sales, while Rigetti is betting on superconducting quantum processors and future scalability.

Why Quantum Computing Stocks Are Gaining Attention

Quantum computing is seen as a possible next-generation technology that could solve complex problems faster than classical computers in areas like logistics, cybersecurity, chemistry, finance, and artificial intelligence. However, the sector is still early, risky, and highly speculative.

Recent government interest has also lifted the sector. Reports noted that U.S. quantum-related funding has supported companies including D-Wave and Rigetti, helping investors view the industry as strategically important.

D-Wave Quantum: Stronger Near-Term Business Momentum

D-Wave Quantum is known for quantum annealing, a specialized approach designed mainly for optimization problems. This makes D-Wave different from many quantum peers because its systems are already being used in practical commercial and government projects.

Compared with Rigetti, D-Wave appears to have a clearer near-term revenue story. Analysts have pointed to its bookings growth, system sales, and customer adoption as signs that QBTS may be better positioned in the short run.

The main strength of D-Wave is that it is not only selling a future vision. It is also trying to build today’s business through cloud access, enterprise use cases, and direct system sales. That gives investors more measurable data to track.

Rigetti Computing: A Long-Term Technology Bet

Rigetti Computing focuses on superconducting quantum processors, a gate-model approach that could become powerful if the technology scales successfully. This path may offer larger long-term potential, but it also requires major technical progress.

Rigetti reported strong first-quarter 2026 revenue growth, with sales rising to about $4.4 million, helped by demand for its Novera quantum processing units and related contracts.

Still, Rigetti remains a high-risk stock. Its revenue base is small, losses continue, and future success depends heavily on technical execution. For patient investors, RGTI may be attractive because its technology could become more valuable if superconducting quantum systems scale well.

Revenue, Risk, and Investor Expectations

Both companies are still in the early stage of commercialization. D-Wave has shown more visible business traction, while Rigetti has shown signs of revenue acceleration from a smaller base. A Motley Fool comparison noted that D-Wave generated much higher annual revenue than Rigetti, but both companies remain far from mature profitability.

This is important because quantum stocks often trade more on expectations than current earnings. When expectations are high, even small disappointments can cause large stock swings.

Which Stock Holds More Promise?

For investors focused on near-term commercial progress, QBTS may look more promising. D-Wave has stronger visible adoption, system sales, and business momentum.

For investors focused on long-term quantum computing breakthroughs, RGTI may offer greater speculative upside. Rigetti’s gate-model strategy could become more valuable if the company proves it can scale its technology.

Overall, the stronger near-term case appears to favor D-Wave Quantum, while the higher-risk, longer-term innovation case supports Rigetti Computing. Neither stock is low risk, and both should be viewed as speculative quantum computing plays rather than stable core holdings.

Final Takeaway

The comparison between RGTI and QBTS shows two very different paths in quantum computing. D-Wave is building a more commercial story today, while Rigetti is pursuing a deeper technology roadmap for tomorrow.

For now, QBTS seems better positioned for near-term promise, while RGTI remains an ambitious long-term bet. Investors should watch revenue growth, customer wins, cash burn, government funding, and technical milestones before making any decision.
