Top Quantum Computing Stocks to Buy in 2025: The Ultimate Growth Play

Quantum computing isn't sci-fi anymore—it's a trillion-dollar race. And these stocks are leading the charge.

Why now? Because classical computing is hitting its limits. AI demands more. Drug discovery needs more. Cybersecurity craves more. Enter quantum.

The Contenders

While Big Tech pours billions into R&D, smaller pure-plays offer asymmetric upside. Some names trade at laughable multiples—because Wall Street still prices quantum like it's 2028.

The Catch

Volatility comes standard. These stocks move 10% on vaporware press releases. But when real quantum advantage hits? Early investors win big.

So forget crypto gambles—this is where the real disruptive money will flow. Just don't expect your broker to understand why.

Alphabet has been working on quantum for years

Before quantum computing grabbed headlines,(GOOG 0.27%) (GOOGL 0.31%) was already investing heavily in the field. It has poured a sizable portion of its massive R&D budget and top-tier talent into the effort, leading to milestones like reaching "quantum supremacy" -- beating a classical computer in a highly limited task -- in 2019. This is exactly where Alphabet excels -- transforming revolutionary science into revolutionary technology.

Alphabet has resources few can match

Onlyand, to a lesser extent,, can match Alphabet's R&D firepower, both from a financial and personnel perspective. At any point, the company could direct the full weight of its R&D budget toward quantum -- tens of billions of dollars. And when the time comes to commercialize the technology, Alphabet can quickly and readily deploy it through its existing cloud infrastructure.

Alphabet gives you much of the upside with almost none of the risks

If the technology takes five, 10, or more years to reach its potential, Alphabet's steady cash flows mean it never has to worry about where it will find its next six months of funding. That's certainly not true for,, and companies like them. And in the meantime, with Alphabet, you get a mature, highly successful tech company at the forefront of artificial intelligence and a stock that trades at a discount to many of its big tech peers.
