Want to Invest in Quantum Computing? 3 Stocks That Are Great Buys Right Now

Investing in a promising early stage technology can be risky. That's especially the case with smaller up-and-coming companies that have yet to generate profits. But sometimes less risky alternatives exist.

Do you want to invest in quantum computing? These three stocks are great buys right now -- and they won't keep you up at night.

1. Alphabet

Alphabet's (NASDAQ: GOOG) (NASDAQ: GOOGL) Google Quantum AI garnered a lot of attention last month. The unit announced that its Willow quantum chip ran a verifiable algorithm on hardware that was 13,000 times faster than the most powerful classical supercomputers. Such a feat is referred to as achieving quantum advantage. And it's a big deal.

Google Quantum AI still has a long way to go. It has checked off two of the six milestones on its quantum computing roadmap. However, Alphabet's team believes they will be able to build a practical quantum computer that can solve real-world problems by the end of the decade.

Quantum computing is only one potential growth driver for Alphabet, though. The company remains an advertising juggernaut with Google Search, YouTube, and other apps. Google Cloud is the fastest-growing of the big three cloud service providers. It should have tremendous growth opportunities as agentic AI adoption increases. Meanwhile, Alphabet's Waymo unit is leading the charge in what could be a massive robotaxi market.

Every major part of Alphabet's business delivered double-digit growth in the latest quarter. For the first time in its history, the company raked in revenue of over $100 billion. Alphabet's full-year revenue should be in the ballpark of $400 billion, with more than one-third of the amount in profits.

2. Amazon

You might not hear Amazon (NASDAQ: AMZN) mentioned all that often when the topic of quantum computing comes up. However, the company's Amazon Web Services (AWS) unit made waves in February 2025 with the introduction of its Ocelot quantum computing chip. Ocelot can reduce the costs of quantum error correction by up to 90% versus current chips.

AWS is also a top platform for organizations working with quantum computing. The cloud service provider's Amazon Braket supports building quantum software, researching quantum computing algorithms, and testing hardware that uses different approaches.

Of course, quantum computing isn't the main reason to consider investing in Amazon. That honor belongs to AWS, which remains No. 1 in the cloud services market. AWS continues to grow briskly, with revenue jumping 20% year over year in the third quarter of 2025. It's also Amazon's most profitable segment.

Don't ignore Amazon's other businesses, though. The company still reigns supreme in the e-commerce market. It has expanded into groceries, healthcare, and more. Amazon should easily generate sales of over $700 billion this year.

3. Microsoft

Microsoft (NASDAQ: MSFT) has its eyes set on the quantum computing opportunity, too. The tech giant believes it's onto something transformative with the development of topoconductors, a new type of material. Microsoft's Majorana 1 is the first quantum processor to use this breakthrough.

Like AWS, Microsoft's Azure cloud platform is also a hub for quantum computing. Like Alphabet's Google Quantum AI, Microsoft has also achieved two of the six milestones on its quantum computing roadmap.

Wall Street is arguably more bullish about Microsoft than any other quantum computing stock. All of the 57 analysts surveyed by S&P Global (NYSE: SPGI) in November rated Microsoft as a "buy" or "strong buy." The consensus 12-month price target reflects an upside potential of more than 16%.

What's the main reason for this optimism on Wall Street? Microsoft's opportunities related to AI. The company generated revenue of $77 billion and profits of $27.7 billion in its latest quarter, with its AI products and services providing a huge tailwind.
