French National Quantum Update: September 2026

Executive Summary

The summer break is definitely over.

France’s quantum sector focused on the manufacturing, software and commercial relationships needed to put quantum computers into wider use in September 2026. Quobly reported progress on chips made through an industrial semiconductor process, while Alice & Bob and Quandela outlined efforts to connect quantum processors with conventional computing infrastructure.

Quobly reported qubit readout and single- and two-qubit operations on devices fabricated at STMicroelectronics’ commercial 300 mm facilities in Crolles, France. The results provided an initial validation of its approach to manufacturing silicon quantum processors. The company also expanded its collaboration with CEA-Leti through access to the FAMES Pilot Line, where it can evaluate manufacturing processes for later processor generations.

Supporting infrastructure featured in two other Quobly agreements. The company signed a memorandum of understanding with Orange Quantum Systems to collaborate on testing silicon spin-qubit devices at scale. A separate industrial partnership with Absolut System will support the cooling systems needed for successive generations of Quobly’s computers, following an initial milestone in their cryogenic platform program.
