Quobly, the Grenoble-based developer of silicon-based quantum processors, has officially opened a Canadian subsidiary in Sherbrooke, Quebec. The expansion is designed to integrate Quobly into the North American quantum ecosystem, specifically targeting collaborations in silicon spin qubit research, advanced packaging, and cryogenic infrastructure. This move follows the company’s established R&D operations in France and Singapore, aligning with its 2032 industrial roadmap to deliver a fault-tolerant universal quantum computer.
The Sherbrooke facility will leverage the region’s existing microelectronics and quantum engineering infrastructure. Quobly has joined DistriQ, the Quebec quantum innovation hub, and will utilize the technological platforms of the C2MI (Centre de collaboration MiQro Innovation) and the Université de Sherbrooke’s Institut Quantique. These partnerships are intended to accelerate the development of cryo-electronics interfaces and hardware-software co-design. The company plans to recruit approximately ten engineers and researchers in Canada over the next three years to support these localized R&D activities.
Technically, Quobly’s approach relies on silicon spin qubits fabricated using standard CMOS/VLSI semiconductor processes. By utilizing Fully Depleted Silicon-On-Insulator (FD-SOI) technology, the company aims to manufacture qubits that are compatible with existing mass-production foundries, such as those operated by its partner STMicroelectronics. The platform’s key differentiators include compact qubit footprints (approx. 100nm²) and higher operating temperatures (up to 1.5 K) compared to superconducting modalities, which reduces the cooling overhead required for large-scale integration.
The Canadian expansion specifically targets the “materials-to-manufacturing” bottleneck by facilitating hybrid approaches that combine classical high-performance computing (HPC) with quantum processing units. This strategic presence in Quebec allows Quobly to interface with Montreal’s software ecosystem to optimize the middleware layers necessary for fault-tolerant operations. The initiative is supported by Investissement Québec International, reflecting a broader effort to verticalize the quantum supply chain between European semiconductor manufacturing and North American systems integration.
