Quantum leader Quantinuum has raised $600 million at a $10 billion valuation, adding Nvidia’s NVentures, Quanta Computer, and QED to an investor pool that includes JPMorgan, Mitsui, Amgen, and Honeywell.

Proceeds will accelerate development of Helios, a next-generation system launching this year, and advance long-term goals in fault-tolerant quantum computing. Quantinuum has positioned itself as a full-stack player with industry-leading benchmarks.

It is deepening ties with Nvidia at the Accelerated Quantum Research Centre and pursuing partnerships blending AI and quantum. The company is also expanding globally with projects in Qatar, Singapore, and the U.S. Qatar’s collaboration forms part of a $1 billion national initiative.

Founded as Cambridge Quantum in 2014, Quantinuum now employs 630 staff across four continents. The raise signals heightened global investor confidence in the quantum race.
