Quobly Tech Stack

Fault-tolerant quantum computers using semiconductor manufacturing

IT Services and IT Consulting Grenoble, Auvergne-Rhône-Alpes 51–200 employees Founded 2022 Privately Held

Quobly is building fault-tolerant quantum computers from semiconductor qubits, leveraging 15 years of collaborative research from CEA Leti and CNRS. The stack—Linux, Zynq, C/C++, Rust, Python, GDSII, Calibre—reflects a hardware-first engineering culture bridging semiconductor fab processes and quantum control. Active projects span quantum error correction schemes, control electronics, embedded firmware, and 300mm advanced technology development; the senior-weighted hiring mix (5 of 11 open roles) and focus on productizing research code signal a maturation phase moving from lab prototypes toward manufacturing-ready systems.

About Quobly

Quobly develops fault-tolerant quantum computers built on silicon-spin qubits manufactured using proven semiconductor processes. Founded in 2022 as a spinout from CEA Leti and CNRS, the company addresses the twin challenges of qubit design and industrial-scale production—two barriers blocking practical quantum systems. Based in Grenoble, the company now employs over 70 people and raised €19 million in seed funding in 2023. The team brings together semiconductor industry veterans and quantum physics researchers; current hiring is concentrated in France across engineering and research roles.
