Quantum computing is back in focus as policymakers push national strategies, enterprises pilot real workloads, and traders chase the AI–quantum crossover. Between fresh technical milestones, new developer toolkits, and growing government support, this corner of tech is setting up for another round of momentum.

Here are three quantum computing stocks I’m watching right now!
3 Top Quantum Computing Penny Stocks to Watch in September
| Stock Ticker | Company | Performance (YTD) |
| NASDAQ: RGTI | Rigetti Computing Inc | |
| NYSE: QBTS | D-Wave Quantum Inc | |
| NYSE: IONQ | IONQ Inc |
The market has tightened up, but quantum momentum hasn’t disappeared — it’s just flowing toward the names with hard catalysts. Traders are rewarding technical breakthroughs, enterprise adoption, and government funding … and punishing everything else.
That’s why these three stand out right now:
- Clear near-term catalysts, from milestone fidelity results to AI-integration announcements and Wall Street coverage.
- Alignment with the quantum + AI crossover story, one of the strongest narratives of 2025.
- Liquid charts with obvious levels for both breakout and breakdown setups.
I’m not saying these are “buy and hold” stocks — they’re highly speculative, and that’s the point.

But here are the three quantum names I’m watching most closely…
Rigetti Computing (NASDAQ: RGTI) — Breakthrough Fidelity, Modular Scale
Rigetti has been one of the sector’s wildest runners into 2025, and the story just got stronger. The company reported 99.5% median two-qubit gate fidelity on its 36-qubit system, cutting error rates roughly in half vs. Ankaa-3. Rigetti’s architecture tiles modular 9-qubit chiplets — a practical pathway to scaling past 100+ qubits on near-term timelines. Add in its $5.48M U.S. Air Force award for ABAA fabrication and collaborations with Quanta Computer, Iowa State, and Lawrence Livermore, and you’ve got both validation and funding lining up.
Catalysts to watch
- Next chip tapes/tiling updates toward higher-qubit systems
- Additional U.S. government grants or procurement news
- Follow-on partnerships that move from research to revenue
This is a high-beta name where news drives price. If buyers push through recent range highs (think mid- to high-teens), momentum traders may pile on. If the stock loses the mid-teens on volume, I’m watching the prior base area as the next decision zone.
D-Wave Quantum (NYSE: QBTS) — Quantum–AI Toolkit, Enterprise Traction
D-Wave is the annealing leader with live systems in market: Advantage/Advantage2, the Ocean tools, and Leap cloud access for hybrid classical-quantum workflows. The latest spark: a Quantum AI toolkit that plugs directly into PyTorch, lowering the barrier for ML teams to experiment with quantum methods inside familiar stacks. Early demos include quantum-assisted image generation, and customers like Japan Tobacco and Triumph are already building optimization and AI applications on D-Wave.
Catalysts to watch
- Developer adoption of the PyTorch-integrated toolkit and case studies
- New Advantage2 performance disclosures and uptime/availability stats
- Enterprise wins in logistics, scheduling, and portfolio optimization
When leaders sit just under highs, I watch for clean breakouts and holds to trigger momentum buying. If consolidation fails and price slips into the mid-teens, I’m looking for prior breakout zones to act as support.

IonQ (NYSE: IONQ) — Well-Capitalized Leader With an Aggressive Roadmap
IonQ is the best-known pure-play in gate-model quantum, distributing systems via AWS, Azure, and Google Cloud and co-developing algorithms and hardware. The company’s footprint keeps expanding — from AstraZeneca collaborations in quantum chemistry to a long-term plan that targets a cryptographically relevant machine by 2028 and multi-million-qubit scale by 2030. Recent Street notes highlighted IonQ’s revenue potential into 2030, and a large cash reserve (management has cited ~$1.6B) gives it runway to execute.
Catalysts to watch
- System performance milestones (error rates, algorithm depth)
- New cloud partnerships, pricing tiers, and usage metrics
- Healthcare/chemistry customer wins and roadmap updates
For higher-priced leaders, I favor break-and-hold patterns over prior yearly highs as momentum triggers. If momentum fades, I watch for higher lows to form around prior multi-month bases.
Bottom Line
- Rigetti is the speculative hardware breakout with fresh fidelity gains and government backing.
- D-Wave is the enterprise-ready annealing play tapping directly into AI/ML workflows.
- IonQ remains the sector’s blue-chip: deep partnerships, capital, and a bold roadmap.
I’m tracking catalysts, letting price confirm, and trading the plan — not the promise.
