IonQ CEO Tells Barron's It Wants to Become "Nvidia of Quantum Computing"

IonQ CEO Niccolo de Masi told Barron's it wants to become the Nvidia of quantum computing.

“We’re in the business of quantum just like Nvidia and Broadcom are in the business of classical GPUs,” de Masi told the news outlet. “I believe IonQ will be the Nvidia player. There will be other people that copy us and follow us; they have always copied and followed us.”

“We feel good about our competitive positioning because, at the end of the day, we are trying to drive ecosystem,” de Masi added.

D-Wave announces Advantage2

Investors are likely excited by news on Tuesday morning in which D-Wave announced the general availability of its sixth-generation Advantage2 quantum computing system, which the company says has a demonstrated ability to solve deeply complex problems that classical computers can’t.

“It’s what everybody aspired to achieve, and we’re quite excited about it,” CEO Alan Baratz told Fast Company in March, when the company announced that it had achieved “quantum supremacy” using the Advantage2.

Although some researchers have challenged D-Wave’s claims, investors appear to be on board for now.

Nvidia in Advanced Talks to Invest in PsiQuantum

Nvidia is in advanced talks to invest in quantum computing startup PsiQuantum, The Information reported on Sunday.

Reuters reported in March that PsiQuantum is raising at least $750 million from investors including BlackRock at a $6 billion pre-money valuation.

Quantum technology has the potential to perform types of calculations that would stump even the most powerful artificial intelligence systems that use Nvidia chips and could unlock a host of scientific and commercial applications, including cybersecurity.

Quantum Computing Inc rises, falls, and rises again

Hoboken-based Quantum Computing Inc. (Nasdaq: QUBT) has seen some volatility since it released its first-quarter 2025 earnings report last Thursday.

The company swung to a profit, reporting net income of $17 million, versus a net loss of $6.4 million last year. Shares surged double digits on Friday after the report, but then fell more than 8% on Monday, possibly due to some profit taking from investors who wanted to lock in their gains.
