Although quantum computing is not currently a primary revenue source for Alphabet, the company is likely the stock of choice in this industry in 2025. That may disappoint investors, as the company does not mention quantum computing in its earnings releases, nor does it report any revenue or funding tied to that technology.

Quantum Computing Inc. (NASDAQ: QUBT) just crossed into the green for the year after a 25.4% single-day surge. It is by far the best-performing quantum computing stock today and the poster child for the quantum-computing melt-up that followed Nvidia CEO Jensen Huang’s unexpectedly bullish comments at the GTC Paris conference.

Quantum computing stocks have been quite volatile over the past six months. Instead, I prefer more mature companies that can devote significant capital to quantum computing research, rather than relying on external funding.
