UK-founded Quantinuum, controlled by Honeywell, has secured $600 million in new funding, valuing the company at $10 billion. Backers include Nvidia’s NVentures, Quanta Computer, QED, and longstanding investors like JPMorgan and Amgen.

Funding will speed up the launch of Helios, Quantinuum’s advanced system debuting this year, and fuel work on fault-tolerant computing. The company has partnered with Nvidia via the Accelerated Quantum Research Centre to bridge quantum and AI.

Global expansion continues into Qatar, Singapore, and the U.S., with Qatar committing $1 billion to its quantum program. Quantinuum now has 630 employees, most of them scientists and engineers.
