Catenaa, Thursday, September 04, 2025- Nvidia’s venture capital arm is investing in Quantinuum for the first time, valuing the quantum computing company, which is controlled by Honeywell International, at $10 billion.
Quoting people familiar with the matter, Bloomberg reported that Nvidia is the latest big-name backer to join the ranks of Quantinuum’s investor roster through a $600 million funding round that could be announced as soon as Thursday.
Nvidia’s CEO, Jensen Huang, has reset his forecast for quantum computing this year, saying in June that the technology is reaching an inflection point and is becoming a practical computing technique sooner than previously expected.
Nvidia now provides software that will help its chips work with quantum devices, positioning the company to take advantage of advances that could disrupt its dominance of computing and data centers.
Quantum computing will be powerful enough in the coming years to help “solve some interesting problems” globally, Huang said. He said Nvidia’s entire quantum algorithm stack will be available and accelerated on its Grace Blackwell 200 chip.
Quantinuum is already a partner with Nvidia on that company’s Accelerated Quantum Research Center, a facility in Boston designed to advance the technology.
Honeywell, which owns about 54% of Quantinuum, is also participating in the financing, alongside QED Investors, JPMorgan Chase & Co, Mitsui, and Amgen, the Bloomberg report said.
The report couldn’t verify what portion of the $600 million round is being invested by Nvidia’s venture arm, which is part of the company’s wide-ranging investments in AI.
Other new investors in Broomfield, Colorado-based Quantinuum include venture capital firm Mesh and Korea Investment Partners, among others, the report said.
Quantinuum disclosed last week in a filing that 35 unnamed investors had participated in a funding round, which confirmed a previous Bloomberg News report.
