Quantinuum plans to expand its Nexus software alongside successive quantum hardware generations, adding tools for error correction and hybrid computing as the company targets a 2029 launch for Apollo, its planned universal, fully fault-tolerant system.
Announced Nov. 5, the roadmap groups development into three stages: building applications, optimizing them and deploying them. Quantinuum says the platform is intended to help developers carry applications forward as its hardware advances from Helios to Sol and Apollo. Nexus, launched in 2024, brings programming, validation, compilation and execution into one environment, available through cloud and on-premises access.
The company reported that 215 organizations used Nexus, with adoption nearly 20% higher than in the previous quarter. Job submissions increased tenfold in the 12 months through August 2026 compared with the preceding 12 months, according to Quantinuum’s quarterly release.
Quantinuum’s Sept. 29 pre-release included Guppy FT, a framework for work on error-correction designs and fault-tolerant program execution. The company says developers can encode programs for supported correction schemes, test them in emulation and execute supported programs on Helios.
Future Nexus releases are intended to automate more of the encoding, compilation and resource-management work. Quantinuum also plans to add diagnostics, error recovery and tools to coordinate quantum systems with classical computing, high-performance computing, cloud infrastructure and third-party software.
José Ignacio Latorre, director of the Centre for Quantum Technologies, said developer platforms “help us bridge that gap between quantum algorithm design and deployment.” Quantinuum’s quarterly release said Sol’s integration and assembly are targeted for the first quarter of 2027, with the system on track for the second half of that year.
Quantinuum expects the next Nexus release in December 2026, with expanded hybrid workflows, more supported error-correction codes and execution analytics.
