A three-way collaboration rooted in FD-SOI manufacturing aims to turn quantum computing from a lab curiosity into an industrial product—without bespoke fabs or bleeding-edge nodes.

Quantum computing has no shortage of impressive laboratory results. What it still lacks, almost universally, is a credible path from those results to machines that can be manufactured, replicated, and deployed at scale. For Grenoble, France-based startup Quobly, that gap—rather than qubit physics itself—is the core problem to solve.
The company’s strategy is shaped by a deliberately unglamorous premise: If quantum processors are ever to move beyond bespoke demonstrators, they must be designed from the outset to live inside the constraints of the semiconductor industry. That conviction underpins the company’s reliance on fully depleted silicon-on-insulator (FD-SOI) technology and its close collaboration with STMicroelectronics (STMicro) and substrate supplier Soitec.
Rather than inventing an exotic qubit platform and worrying about scale later, Quobly is doing the opposite: starting with an industrial platform and accepting the constraints it imposes on qubit design.
