Want to Invest in Quantum Computing? 3 Stocks That Are Great Buys Right Now.
Summarize this article with:
Did a small quantum computing company just acquire a business that will give it a competitive advantage?I've excitedly monitored the field of quantum computing for roughly a decade now. This "next wave" of computing promises to solve complex problems that traditional computers can't touch. However, I've been reluctant to invest in pure-play quantum computing companies because the technology isn't fully developed. It could still be years before these businesses generate meaningful revenue, making investment difficult. That being said, I'm increasingly willing to make an exception for IonQ (IONQ +9.01%). Image source: Getty Images. Quantum computing companies are targeting systems with more than 1 million qubits, compared to the hundreds of qubits today. A system of over 1 million qubits will be so powerful that I believe it matters which company reaches this milestone first. This is why I'm starting to like IonQ. In short, IonQ is running with leaders in quantum hardware, yes. But the company is in the process of acquiring SkyWater Technology (SKYT +2.82%), which will make it a leader in manufacturing as well. This vertical integration will allow IonQ to iterate more quickly to improve its hardware. And it will also allow it to scale faster when the time comes.

However, for those looking for a more diversified quantum computing play, look no further than Alphabet (GOOG 1.08%)(GOOGL 1.08%). With over $400 billion in trailing-12-month revenue, it clearly doesn't need to win quantum to survive. Alphabet is a top quantum stock because it's been working on the problem for more than a decade and has virtually unlimited financial resources to throw at it. Moreover, the company's new Willow chip gets better at correcting its errors as the system scales, according to those working on the project.

Because qubits are hard to control, hard to read, and can be unstable, errors occur. Quantum computing companies are trying to improve hardware. But error-correcting software will likely always be an important part of making everything work. This is why I believe IBM (IBM +1.05%) would be a third quantum computing stock for investors to consider. IBM is working on hardware. But its quantum computing software development kit (SDK) appears to really be gaining momentum. It's open source and has been downloaded over 13 million times, which objectively makes the company a leader here. And, according to some reports, it's the most popular quantum computing SDK among developers. Therefore, it's possible that IBM could be a winner in quantum computing software even if another company wins in hardware. In summary, I believe three quantum computing stocks worth buying today are IonQ, Alphabet, and IBM because each has its own advantages. But I will temper expectations by saying that quantum computers still need to improve over the coming years, which means investors will need to be patient as the space develops.Read NextFeb 13, 2026 •By Harsh Chauhan2 Tech Stocks That Could Go ParabolicFeb 13, 2026 •By Sean WilliamsThe Quantum Computing Stock Risk Everyone (Even Wall Street Analysts) Is MissingFeb 12, 2026 •By Geoffrey SeilerCould Buying IonQ Today Set You Up for Life?Feb 12, 2026 •By Leo Sun2 Reasons IonQ Is the Top Quantum Computing Stock to Buy Right NowFeb 11, 2026 •By Adam SpataccoWhere Will IonQ Stock Be in 1 Year?Feb 10, 2026 •By John Ballard2 Top Quantum Computing Stocks to Buy in 2026About the AuthorJon Quast is a contributing writer for The Motley Fool covering consumer goods, technology, and cryptocurrency.
