IonQ, QUBT, RGTI—Alphabet Soup Turns Into a Quantum Feast
Quantum computing breaks out of theory and into market reality as Nvidia, IBM, and others accelerate development—and investors rush in.

Quantum computing just got its biggest vote of confidence yet—and investors are already placing their bets.
On Wednesday morning, shares of several leading quantum computing companies surged after Nvidia CEO Jensen Huang made strikingly optimistic remarks at the GTC Paris developer conference. Huang, whose company has become synonymous with the AI revolution, told a packed room, “We are within reach” of deploying quantum computing to solve “some interesting problems in the coming years.” With that single sentence, the tide turned for an entire industry.
The markets didn’t hesitate. Quantum Computing Inc. (QUBT) rocketed over 30% in early trading. Rigetti Computing (RGTI) jumped more than 17%, and IonQ (IONQ), one of the most recognized players in the space, climbed a solid 7%. Meanwhile, the broader market stayed quiet—the S&P 500 remained flat.
Huang’s statement was more than just a passing comment. It signaled a shift in tone and timeline. Just a few months ago, in January, Huang warned that “very useful quantum computers” could still be 20 years away—a sobering remark that sent shockwaves through the nascent quantum sector. Since then, Nvidia has doubled down. The company hosted its first-ever “Quantum Day” this past March and announced a new quantum research center to be built in Boston. Now, the message is clear: Nvidia is not just watching from the sidelines. It wants in.
