Quobly is a French silicon quantum computing company building spin-qubit processors through semiconductor manufacturing. It spun out of CEA-Leti and partners closely with STMicroelectronics, aiming to make quantum chips with industrial CMOS-style processes.
After a EUR 19M seed phase and EUR 21M project funding, Quobly announced a EUR 115M Series A in June 2026 to bring silicon-based quantum computers to market and accelerate international commercialization.
In September 2026, Quobly demonstrated readout, single-qubit gates and two-qubit gates on one industrially fabricated QSOI chip, made Alloy Forge available through qBraid, and expanded pilot-line access with CEA-Leti as it prepares Alloy Pioneer cloud access by year-end.
