What Quobly does

Quobly is a French deep-tech company founded in 2022 as a spin-off of CEA-Leti and CNRS, headquartered in Grenoble, that develops silicon-based quantum processors built on 28nm FD-SOI technology and fabricated at STMicroelectronics' 300mm commercial fab in Crolles, France. Its quantum bits are encoded as electron spins trapped in quantum dots on silicon-28 substrates, with cryo-CMOS control electronics co-integrated on the same die, enabling operation at relatively high cryogenic temperatures (500 mK–1.5 K) and a 65-patent IP portfolio. The company has demonstrated fabrication of 2.4+ million qubits at industrial scale and targets a roadmap to fault-tolerant million-qubit systems by 2032.

Quobly's commercial offering centers on the Alloy product line, anchored by Alloy Pioneer — the first commercial silicon-spin quantum computer designed for rack-scale deployment in existing data centers — supported by the Alloy Forge quantum application development environment and the QLEO GPU-accelerated quantum emulator developed with QPerfect and integrated with NVIDIA CUDA-Q. Distribution is planned through two channels: OVHcloud's Quantum-as-a-Service platform (cloud access from late 2026) and direct enterprise sales to HPC facilities, research institutions, and government/defense organizations (HPC deployment from 2027). Primary target use cases are quantum chemistry and materials science, combinatorial optimization in logistics and finance, and sovereign defense applications.

The business model combines future hardware sales/leasing of the Alloy line with subscription-based cloud access (pay-per-use on OVHcloud) and software/emulator access revenue. The company has raised €134M+ to date (€19M seed in 2023 plus a €115M Series A in June 2026) led by Bpifrance, SEALSQ, and STMicroelectronics, with backing from EIC Fund, Air Liquide's ALIAD, and existing investors Quantonation, Innovacom, Supernova Invest, CEA, and CNRS. The team of 100+ (planned to double to 200) is 54% PhDs, and the company maintains R&D and commercial operations across Grenoble, Sherbrooke (Canada), and Singapore.

Core offering

Quobly develops silicon-based quantum computers built on FD-SOI (Fully Depleted Silicon-On-Insulator) technology on 300mm wafers using conventional semiconductor manufacturing at STMicroelectronics' Crolles fab. The company encodes quantum information in silicon spin qubits with cryo-CMOS control electronics co-integrated on the same die, and sells/leases its Alloy product line (starting with Alloy Pioneer) for cloud access and HPC deployment. Complementary offerings include the QLEO GPU-accelerated quantum emulator and the Alloy Forge quantum application development environment.

Product overview

Quobly is a quantum computing company developing silicon-based quantum computers built on proven semiconductor manufacturing processes (FD-SOI on 300mm wafers), targeting scalable, affordable, and data-center-ready quantum systems. Its commercial product lineup consists of the Alloy product line — anchored by Alloy Pioneer, the first commercial quantum computer planned for cloud deployment in late 2026 and HPC deployment in 2027 — complemented by Alloy Forge, a quantum application development environment for building and validating algorithms under realistic hardware constraints. Quobly also offers QLEO, a GPU-accelerated quantum emulator developed with QPerfect featuring NVIDIA CUDA-Q native compatibility, which serves as a bridging tool between classical simulation and future quantum hardware access on the OVHcloud Quantum Platform.
