Honeywell announced an approximately $600 million equity capital raise for Quantinuum, developer of the world's highest-performing quantum computer, at a pre-money equity valuation of $10 billion.

Quanta Computer, NVentures (NVIDIA's venture capital arm) and QED Investors have joined existing shareholders JPMorganChase, Mitsui, Amgen, Cambridge Quantum Holdings, Serendipity Capital and Honeywell — all of whom have reinvested in this round. The round also includes participation from new investors MESH and Korea Investment Partners.

This capital raise will support Quantinuum's advancement of quantum computing at scale, which includes continued progress toward the upcoming launch of Helios, the company's next generation quantum computing system that is expected to launch this year. It will also support Quantinuum's path to becoming the first to perform universal fault-tolerant computing.

A full-stack quantum computing provider, Quantinuum is accelerating commercially useful quantum computing with commercially available quantum computers that are the undisputed leaders in performance. Along with some of the most used developer tools and end-applications such as InQuanto, the company's solutions are driving breakthrough scientific discoveries, economic growth and sustainable development.

Quantinuum will work with NVIDIA as a founding collaborator on breakthroughs at the NVIDIA Accelerated Quantum Research Center.  Additionally, Quantinuum has entered strategic partnerships aimed at innovative quantum computing solutions that will expand the capabilities of classical artificial intelligence and realize next-generation technologies. Quantinuum recently announced partnerships and collaborations with RIKEN, SoftBank Corp., Infineon and STFC Hartree Center, as well as expansions into New Mexico, Qatar and Singapore.

Vimal Kapur, Chairman and CEO of Honeywell: "Quantinuum continues to meet and exceed our stated objectives — strategically, technically and commercially. We have complete confidence in Quantinuum's ability to continue to lead the quantum revolution and create long-term value for its investors and customers."

Scot Baldry, Chief Technology Officer of JPMorganChase: "We have seen firsthand the transformative potential of Quantinuum's technology. We are looking forward to continuing our work together to help accelerate innovation and move closer toward solving real-world problems through quantum applications."

Dr. Rajeeb Hazra, President & CEO of Quantinuum: "We are proud to partner with investors who share deep conviction in our vision for the future of quantum and AI. With the continued support of our customers and supply chain partners, this new funding will further extend our leadership, accelerate our roadmap and strengthen the entire quantum ecosystem."
