State of play
TIME-SENSITIVEupdated 9 November 2026
QUBIT TECHNOLOGIES / HARDWARE APPROACHESIBM, Oak Ridge National Laboratory and AMD announced an error-correction research platform on 5 November. It connects an IBM Nighthawk r2 processor with the Umbra computing system at IBM’s Poughkeepsie site. The platform is designed to test low-latency decoding and control for future fault-tolerant machines.MAJOR HARDWARE COMPANIES / FULL-STACK PLAYERSIonQ reported third-quarter revenue of $173.8m on 5 November and raised its full-year revenue guidance to $505m–$515m. Quantinuum reported $9.1m for the same quarter and raised its guidance to $31m–$34m. Revenue, cash and accounting profit measure different parts of these companies’ finances.SOFTWARE / CLOUD / DEVELOPER PLATFORMSQuantinuum’s 5 November Nexus roadmap describes software for developing and running error-corrected programs on Helios. The company reports 215 organisations using Nexus. More codes, execution analytics and responsive hybrid workflows are planned for December; Apollo remains a 2029 hardware target.
