TLDR
- D-Wave Quantum stock has risen 3,700% in 12 months, driven by quantum annealing device sales reaching $3.1 million in Q2
- Rigetti Computing shares jumped 5,700% over the last year, securing $5.7 million in quantum system orders for 2026 delivery
- IonQ uses trapped-ion technology for better accuracy at room temperature, while D-Wave focuses on optimization problems
- Both D-Wave and Rigetti remain unprofitable with Q2 operating losses of $26.5 million and $19.9 million respectively
- Nvidia develops CUDA-Q software to integrate quantum computing with existing infrastructure, bridging traditional and quantum systems
D-Wave Quantum and Rigetti Computing have posted extreme stock gains over the past year. D-Wave shares climbed 3,700% while Rigetti soared 5,700%. The rallies come as investors shift focus from AI to quantum computing opportunities.
D-Wave reported second-quarter revenue of $3.1 million, up 42% year over year. The California company sells quantum annealing devices designed for optimization problems. These systems are already in commercial use, helping Turkish vehicle manufacturers improve efficiency and assisting Japanese drug discovery efforts.
Rigetti Computing announced purchase orders totaling $5.7 million in late September. The company expects to deliver two quantum computing systems in the first half of 2026. Rigetti positions itself as a hardware provider, supplying chips and processors to other companies developing quantum platforms.
Different Approaches to Quantum Technology
IonQ takes a trapped-ion approach to quantum computing. This method operates at room temperature and offers better accuracy than superconducting techniques. The company trades processing speed for improved precision, addressing one of quantum computing’s main challenges.
D-Wave specializes in quantum annealing rather than general-purpose computing. This technology targets optimization problems like logistics networks and AI model training. The company’s Q2 gross margin reached 82.46%, though it still operates at a loss.
Rigetti’s second-quarter revenue fell 42% to $1.8 million. The company lost $19.9 million in operations during the same period. Despite the revenue decline, Rigetti continues attracting research institutions testing quantum technology.
Current Financial Performance
D-Wave posted operating losses of $26.5 million in Q2. The company trades at a price-to-sales ratio of 336 with a market cap around $12 billion. IonQ carries a market cap of $21 billion with a gross margin of 1.14%.
Both D-Wave and Rigetti face profitability challenges. High cash burn rates continue as both companies develop and commercialize their technology. Revenue remains low compared to their market valuations.
Nvidia entered the quantum space through software development. The chip maker created CUDA-Q to integrate quantum computing units with existing infrastructure. Data center capital spending is expected to grow from $600 billion this year to $3-4 trillion by 2030.
The quantum computing industry points to 2030 as the target for commercial viability. Companies are working to solve accuracy and stability issues before widespread adoption can occur. D-Wave’s technology is already deployed in real applications, giving it an early commercial presence.
IonQ’s trapped-ion systems show promise for accuracy improvements. D-Wave’s quantum annealing serves specific use cases like the traveling salesman problem. Rigetti pursues a picks-and-shovels strategy, supplying hardware to platform developers.
All three quantum stocks carry high risk due to uncertain timelines. The technology may take years or decades to reach full commercial deployment. Extreme volatility marks the sector as companies burn cash while building their products.
