Quobly bets quantum runs on existing chip fabs; €115M Series A, first product due 2026

Quobly is betting that the way to scale quantum computing is not a breakthrough in physics but a breakthrough in manufacturing: build qubits on FD-SOI silicon using proven 300mm semiconductor processes, then let the chip industry's yield engineering do the scaling. Founded in Grenoble in 2022 by CEA-Leti and CNRS researchers Maud Vinet and Tristan Meunier, the company argues that other qubit platforms hit a wall when each machine has to be hand-assembled, while silicon qubits can ride existing fabs.

The thesis attracted industrial money early: a €19M seed in 2023 (a European record for quantum hardware at the time), then €21M in May 2025 to industrialize its Q100T 100-qubit processor. In June 2026 Quobly closed a €115M Series A led by Bpifrance, STMicroelectronics and Nasdaq-listed SEALSQ, with the EIC, Blast and Air Liquide Venture Capital participating, and STMicroelectronics' R&D chief publicly framed the round as the moment quantum computing entered semiconductor-grade industrialization.

The company's first commercial system, Alloy Pioneer, is designed to slot into existing HPC and data-center environments with compatible footprint, power and utility requirements, and is scheduled for cloud access by the end of 2026 with on-site HPC deployment in 2027. Quobly had more than 100 employees as of the June 2026 round and offices in France, Singapore and Canada.
