My Three Favorite Quantum Computing Stocks for May 2026

May 11, 2026

Quantum computing might not be stealing the limelight from artificial intelligence (AI) at the moment, but its time could come. Many forecasts suggest that practical quantum computing could become a reality around 2030, which is, honestly, just around the corner. A number of companies are already making strides in this field, and I think there are a few that definitely deserve some attention.

On my purchase list for May, three companies stand out: IonQ (NYSE:IONQ), D-Wave Quantum (NYSE:QBTS), and Alphabet (NASDAQ:GOOG) (NASDAQ:Google). Each of these firms is a significant player in the quantum computing arena and is currently finding success. I have a feeling that by 2030, these companies could be at the forefront of the industry, and investing in them now might lead to considerable gains.

Will AI create the world’s first millionaire? Our team recently published a report on a lesser-known company named “Indispensable Monopoly,” which provides essential technology for both Nvidia and Intel.

1. IonQ

IonQ (NYSE:IONQ) is frequently cited as a leading choice for pure quantum computing, boasting high precision. The industry currently faces two main hurdles to widespread adoption. First, there’s the challenge of accuracy. Quantum computers frequently fall short of delivering precise results suitable for commercial use, and sometimes their output can blend in with background noise. Secondly, it’s all about the number of qubits in the system. Qubits, which are the basic units of quantum computing (as opposed to classical bits), need to be optimized to handle operations at a scale necessary for commercial applications, and firms are all racing to enhance these aspects of their technology.

IonQ is excelling in both areas, achieving a remarkable 99.99% two-qubit gate fidelity, surpassing its competitors. They’re also working on a 256-qubit system that aims for similar fidelity levels. If IonQ manages to pull this off, the demand for its products could skyrocket due to its superior technology.

Additionally, IonQ has formed numerous research collaborations and technology agreements, propelling significant growth. Revenue in the first quarter of 2026 jumped by 755% from the previous year, highlighted by the sale of their first 256-qubit unit—a sign that the future of quantum computing may not be as far off as it seems.

IonQ is certainly a top contender in the quantum landscape; investors should take note.

2. D-Wave Quantum

Quantum computing can be approached in various ways, and not all involve traditional gating methods. D-Wave Quantum (NYSE:QBTS) emphasizes solving optimization problems instead of relying solely on gate logic, establishing a unique niche in the market. Their quantum annealing computers are actively used to tackle industry challenges involving scheduling and logistics.

This focus has contributed to considerable growth, with revenue increasing by 179% from 2024 to 2025. If D-Wave can successfully carve out its niche even further, the potential for investment success seems promising.

3. Alphabet

Finally, there’s Alphabet (NASDAQ:GOOG) (NASDAQ:Google). As a major contender in this field, Alphabet has already made several breakthroughs in quantum technology. Interestingly, they don’t have to shout about their advancements as loudly as some others since they often compete for resources internally.

They’ve even discovered ways to breach security protocols in their cryptocurrencies, suggesting these need updates by 2029 to avoid vulnerabilities from potential quantum computing attacks. This indicates that Alphabet’s quantum technologies are maturing and could soon lead to significant developments, especially if they become the first quantum service available on cloud platforms.

Investing in Alphabet seems like a wise choice in this emerging field and might just be one of the safest options in quantum computing.

Should you buy IonQ stock now?

If you’re contemplating buying into IonQ, here are a few considerations:

Our analyst team has identified some of the best stocks to invest in right now, and oddly enough, IonQ isn’t on that list. These picks are believed to hold significant potential for the coming years.

So, it’s worth pondering your strategy—historically, investing in certain companies like Netflix or Nvidia could have resulted in remarkable returns. For example, a $1,000 investment in Netflix back in 2004 would now be worth nearly $471,827. And, similarly, a $1,000 investment in Nvidia from 2005 could grow to around $1,319,291.

It’s noteworthy that the stock advisor program boasts an average return of about 986%, which clearly outshines the S&P 500’s 207% return, showing exceptional performance. So, perhaps it’s a good time to tap into this investing community, structured for retail investors like you.
