Quobly is developing industrial silicon-based quantum computers designed to scale using the same semiconductor infrastructure that powers conventional chips. Rather than building exotic hardware, the company fabricates silicon spin qubits on standard 300mm wafers, engineering them for fault-tolerant systems that can eventually be deployed inside existing data centers.
The approach is built on the bet that quantum computing will only become practical at scale if it can ride the cost, yield, and manufacturing maturity of the established microelectronics industry. Quobly integrates control electronics into chip-based designs and works with semiconductor manufacturing partners including STMicroelectronics, having fabricated millions of qubit structures and filed dozens of patents.
Founded in 2022 in Grenoble, France, Quobly was co-founded by CEO Maud Vinet, a former CEA-Leti quantum program lead, alongside CTO Tristan Meunier and COO François Perruchot, combining deep academic physics with industrial semiconductor know-how. The company employs 90+ experts across multiple locations.
Quobly raised a €115 million (approximately $124 million) Series A to accelerate the industrialization of its silicon-based quantum computers, following an earlier €19 million round. It was also selected for France's PROQCIMA national quantum program alongside peers including Alice & Bob and Pasqal.
Quobly positions itself as the bridge between cutting-edge quantum research and manufacturable, scalable quantum hardware.
