Nvidia CEO Jensen Huang is getting quantum computing fever

Driving the news: Huang told VivaTech 2025 in Paris Wednesday that quantum computing is raring to go — something of a reversal from the outright skepticism he expressed earlier this year.

• "Today I can tell you there's an inflection point happening," Huang said.
• "It is clear now we are within reach of being able to apply quantum computing — quantum classical computing — in areas that can solve some interesting problems in the coming years," he added. "This is a really exciting time."

Context: Nvidia products and technologies are used in quantum development.

• And Huang announced Wednesday that the company's quantum algorithm stack will be paired with its Grace Blackwell 200 chip to accelerate quantum efforts.

The impact: His remarks delivered a burst of investor interest in quantum stocks.

• Quantum Computing Inc shares soared 25% Wednesday, while Rigetti Computing closed up 11%.

How it works: Classical computers, even the most powerful supercomputers, do their calculations through the binary manipulation of bits, which can be in only two states: on or off, 1 or 0.

• Quantum computers use the quantum state of an object to produce what's known as qubits. The complex math behind these qubits can be plugged into special algorithms to do calculations that would be impossible for a classical computer to perform.
• This could have huge implications for everything from drug discovery, to financial modeling, to AI development.

The bottom line: Huang's change of heart comes after he sent quantum stocks plunging in January when he told analysts that he thought "very useful quantum computers" were about 20 years away.
