Shares of eponymous quantum computing company Quantum Computing Inc. (QUBT +12.53%) soared 11.6% through 11 a.m. ET Monday. And why?
That's not entirely clear. There's no significant quantum stock news out today, concerning either Quantum Computing stock in particular or quantum stocks in general. There is a story on Investor's Business Daily today, but it basically boils down to an observation:
Quantum stocks have done very well in 2025.

Quantum Computing in 2025
Make that most quantum stocks have done very well in 2025. Quantum Computing stock, it turns out, is the exception to the rule, with shares down 40%.
Quantum Computing specializes in "quantum optics and integrated photonics technology" to build "accessible and affordable quantum machines" designed to operate at room temperatures (i.e., no super-cooled). Which all sounds great, but Quantum Computing is doing barely $500,000 in annual revenue -- not a lot for a stock valued at $2.4 billion.
Analysts polled by S&P Global Market Intelligence anticipate rapid growth in sales in percentage terms, but even two years out, in 2027, they forecast no more than $15 million in revenue (which works out to about a 163-times price-to-sales ratio). And they don't see Quantum Computing earning any profit as far out as anyone is willing to make projections.

Is Quantum Computing stock a buy in 2026?
How can Quantum Computing change these forecasts?
Perhaps aiming to change the story, Quantum Computing pivoted last week, announcing it will buy semiconductor company Luminar Semiconductor from Luminar Technologies (LAZR 64.44%) for $110 million. Interim CEO Yuping Huang called this "a meaningful step forward in our strategy to develop and scale practical, integrated quantum solutions."
Quantum Computing investors may be happy if it just gets sales over the hump to single-digit millions.
