The best traders watch more than they trade. That’s what I’m trying to model here. Pay attention to the work that goes in, not the picks that come out.
Let’s get to the picks…
Alphabet (NASDAQ: GOOGL, NASDAQ: GOOG)
Alphabet has been at the forefront of quantum computing innovation since unveiling its Sycamore processor, which famously demonstrated quantum supremacy in 2019. Its ongoing investment into quantum circuits, quantum applications, and advanced machine learning models keeps it positioned as a research powerhouse. Recently, the company expanded its collaboration with Nvidia to accelerate quantum simulations using GPU-based architecture—a move that leverages Alphabet’s dominance in cloud computing and algorithms to push computation boundaries even further.
For traders looking at S&P 500 tech giants with real exposure to cutting-edge computation, GOOGL shares offer a unique entry point. While quantum computing remains a small slice of its business, the long-term advantage lies in Alphabet’s ability to integrate quantum systems into its cloud infrastructure and machine learning tools. As someone who has taught trading fundamentals to thousands of students, I always emphasize watching for companies that pair innovation with scale—Alphabet fits that strategy perfectly.
Still, valuation matters. While Alphabet maintains strong financials, its size means major quantum breakthroughs won’t immediately spike the stock like with small caps. But it’s this same stability that makes GOOGL a steady mover during sector rotations. Traders should keep an eye on articles, earnings calls, and quantum-related reviews, especially if Google announces new milestones that increase accessibility or reduce computational errors in quantum models.
Alphabet is a growth stock better suited to long-term portfolios than quick returns… but if you’re looking to leverage a small account in a Google trade, I’d look into the world of options, which give you the rights to trade a stock if it goes your way!
I don’t trade options—I leave it to pros like former hedge fund trader Jeff Zananiri. His Burn Notice strategy identifies the best overnight options trades out there—and his meticulous teaching style ensures you don’t miss the move.

IBM (NYSE: IBM)
IBM has quietly built one of the most mature quantum computing platforms in the world, with more than 75 systems deployed globally and a robust roadmap to scale to thousands of qubits. Unlike most competitors still refining their prototypes, IBM is already offering quantum applications through the cloud, targeting encryption, optimization, and advanced simulations. Its Qiskit platform and decades of experience in hardware innovation give IBM a technical edge, and it’s booked over $1 billion in revenue from quantum contracts since 2017.
From a trading standpoint, IBM is not your high-flyer. But for those building a diversified watchlist, it brings unmatched credibility to the quantum conversation. The company benefits from strategic collaborations with universities and federal agencies and is one of the few with meaningful partnerships across the finance and healthcare sectors. In my own market analysis and daily teaching, I highlight the importance of understanding both volatility and value—IBM doesn’t spike on news like small caps, but it commands long-term trust in institutional portfolios.
The challenge with IBM is accessibility—its quantum computing arm still represents a small portion of overall earnings. But it’s gaining traction fast, especially as its leadership shifts focus toward hybrid cloud and quantum integration. With growing demand for secure calculations and AI-enhanced data workflows, IBM could see performance lift as enterprise clients adopt quantum for real-world applications. Keep an eye on earnings transcripts and government grant announcements—those can be meaningful catalysts in otherwise steady price action.
Honeywell (NASDAQ: HON)
Honeywell might not be the first name that comes to mind when thinking about quantum stocks, but its ownership of Quantinuum places it squarely in the race. Quantinuum develops quantum circuits and software solutions with a focus on error correction and commercial viability. In 2025, it announced the opening of a new R&D center in New Mexico, a move supported by state and federal funding—a strong indicator of future expansion. Quantinuum’s photonics-based quantum system has already demonstrated innovations in data encryption and drug discovery simulations.
This is a pick where institutional finance meets next-gen technology. Honeywell’s integration of quantum systems into its existing aerospace, automation, and materials divisions allows it to deploy quantum solutions in ways other companies simply can’t. I teach my students to look for synergy between sectors, especially when exploring emerging tech. That synergy gives Honeywell a long-term advantage—and could lead to valuation growth as quantum becomes more embedded in its operational strategy.
For traders, the key is timing. Shares may not respond quickly to quantum-related news, but they offer access to one of the most credible quantum collaborations in the market. Honeywell’s Board of Directors has embraced diversification, and the company’s growing list of patents and performance milestones in quantum computing can act as catalysts. It’s not just about the buzz—it’s about sustained technical innovation and strategic positioning across sectors.
Honeywell’s push into quantum computing shows how legacy companies can adapt fast when the tech is worth it. They’re backing startups, building hardware, and positioning themselves early in a space with long-term upside. But Honeywell isn’t the only name traders should keep an eye on. There are other legit quantum plays that might offer more movement for active traders. Here’s a list of quantum computing stocks to watch right now.
IonQ (NYSE: IONQ)
IonQ is one of the most closely watched quantum computing stocks on the NYSE. As a pure-play in trapped-ion quantum technology, IonQ is attempting to leap ahead in a space where computation, algorithm accuracy, and quantum circuit scalability still pose massive challenges. The company has landed cloud computing partnerships with Amazon and Microsoft and reported Q4 2024 revenues of $11.7 million. But despite beating expectations, shares have pulled back, with traders reacting to slower-than-hoped adoption and a widening loss.
As a trader and educator, I always tell people that the key isn’t just to chase momentum—it’s to understand the story behind the move. IonQ is one of the most speculative bets on the list. Its valuation reflects future potential, not present earnings. The company’s Board of Directors is focused on research and government collaborations, and it continues to generate headlines through academic articles and opinion reviews from the quantum community. That said, it needs more real-world quantum applications to justify its premium.
Right now, IONQ sits at a crossroads. It’s down from its highs, trading near support. That opens the door for bounce trades if the sector heats up again—especially with Nvidia and IBM spotlighting quantum innovations in 2025. For short-term traders, this volatility can be an advantage. But for anyone holding long, understand that errors in system performance or missteps in expansion could cause a sharp recalibration.
Nvidia (NASDAQ: NVDA)
Nvidia is better known for AI, but it’s making strategic moves into quantum computing. At its March 2025 GTC conference, the company spotlighted CUDA-Q—a new platform aimed at improving simulations and reducing errors in quantum calculations. Nvidia has also joined forces with Google Quantum AI, showing it’s not just dabbling in quantum, but pushing toward hardware and software integration in quantum chip development.
This is classic Nvidia strategy—combine strong partnerships with advanced technology, then commercialize at scale. As someone who has taught trading strategies based on real-time market behavior, I’ve seen how news from NVDA can move the entire AI and quantum sector. When NVDA spikes, other tickers like RGTI and QBTS often follow. Its dominance in data, algorithms, and GPU computation makes it a critical player in how quantum applications will be deployed.
Still, traders need to remember that NVDA is an S&P 500 heavyweight. It’s not going to triple in a week, but it often leads sector trends.
That said, traders with smaller accounts might want cheaper exposure to the sector. There are low-priced plays making moves too. Check out this list of quantum penny stocks worth watching.
Rigetti Computing Inc (NASDAQ: RGTI)
Rigetti Computing is a high-risk, high-reward name in the quantum space. After rallying in 2024, shares have dropped sharply following market-wide weakness and disappointing sentiment around IonQ’s earnings. But Rigetti still offers one of the more unique setups in quantum hardware, with a focus on hybrid quantum-classical algorithms and scalable quantum circuits. Its system is already accessible through public cloud platforms, giving it a head start on real-world deployment.
I like to remind students that volatility isn’t a red flag—it’s an opportunity. RGTI is a past runner that could spike again if the sector heats up. The company is still chasing key technical milestones, and its Board of Directors has approved multiple cost-cutting strategies to extend cash runway. That gives it time to build collaborations, pursue grants, and refine performance. But there’s still a real risk here: poor financial health and lack of consistent revenue remain challenges.
The benefit? Traders who time this correctly can catch sharp intraday moves—just like I’ve shown in live market sessions. RGTI can rally 30–50% in a single day on the right catalyst. Articles, insider buys, or news of government contracts could all trigger upside. Just don’t confuse trade setups with investment ideas. Penny stocks in speculative sectors should be traded with tight risk management and a plan. Always.
D-Wave Systems (NYSE: QBTS)
D-Wave is different from other quantum computing stocks—it specializes in annealing quantum computers, which are already being used for optimization problems. Unlike many companies still in research mode, D-Wave has sold quantum systems to research institutions.
The company just made one of the boldest claims we’ve seen in the quantum computing space this year — announcing it achieved “quantum supremacy” by solving a real-world problem that, according to the company, would take a classical supercomputer nearly one million years to complete.
That headline triggered a massive stock market rally. But then came the pushback—most meaningfully after a sharp drop from a share offering. It’s rare to see an early-stage quantum company actually delivering hardware—and real customers. It’s a high-risk play, but one that moves fast and can catch fire on the right catalyst.
Factors to Consider Before Investing in Quantum Computing Stocks
Quantum stocks come with risk, volatility, and big promise—but not every company is worth the hype. Before you commit, it’s smart to get a handle on which ones actually have momentum, funding, and something real behind the name. Don’t guess. Here’s a breakdown of quantum computing stocks to buy and why:
- Financial health: Many quantum companies are pre-revenue and burning cash. If a company is running low on capital, dilution is a real risk (see QBTS’s recent share offering).
- Industry partnerships: Companies like IBM, Google, and Honeywell have partnerships with universities, corporations, and governments. These relationships can drive funding and adoption.
- Intellectual property: Quantum computing is all about breakthroughs and patents. Companies with strong IP portfolios have an advantage.
- Real-world adoption: Quantum technology is still experimental. Companies that can prove real-world applications will be the first to turn a profit.
- Market risks: Quantum stocks move on hype, but real-world commercialization is still years away. That means these stocks can see massive swings.
Market Size and Growth Potential of Quantum Computing
The quantum computing market is projected to grow at a CAGR of over 30% in the next decade. Tech giants, government agencies, and financial institutions are all investing heavily in the space. AI, cybersecurity, and drug discovery are expected to be the biggest industries impacted by quantum computing.
But practical quantum computing is still years away. Until these companies can monetize their technology, stocks will move more on news and speculation than actual earnings.
