Quantinuum maps out Nexus growth ahead of its 2029 fault-tolerant computer

Quantinuum has shared a clear plan for its software side as it heads towards fault tolerance. The Quantum Insider reports that the company has published a roadmap for Nexus, its cloud platform launched in 2024, turning it into a developer platform for fault tolerant applications

The hardware path runs from Helios today, to Sol, and then to Apollo in 2029, which Quantinuum describes as its first fully fault tolerant computer. Nexus is meant to grow alongside each machine so that customers can use new hardware features as soon as they arrive

According to the company, more than 200 organisations now use Nexus, up 45 percent in 2026, and job submissions rose tenfold in the year to August. Guppy FT and Guppy Algorithms shipped in September, and a December release will add hybrid workflows, more error correction codes and execution analytics

Users include Qubit Pharmaceuticals working with Singapore's Centre for Quantum Technologies, and RIKEN with the University of Tokyo, who simulated atomic nuclei on Quantinuum's Reimei system. Oracle Cloud is also integrating Nexus. CEO Rajeeb Hazra said the full stack approach means each hardware advance becomes something customers can build on

Roadmaps are promises rather than results, and the usage figures come from Quantinuum itself. Error correction automation also only works on Helios for now. Even so, a company that invests this much in software clearly expects its hardware to deliver, and developers like having tools ready before the big machines land

Is software the secret weapon in the quantum race? And does 2029 sound realistic for Apollo?
