Quobly, formerly Siquance, was founded in 2022 to develop and commercialize a universal large-scale quantum computer using proven semiconductor-industry processes. At Quobly, we believe in the potential of quantum to solve problems classical computers cannot—and we have a viable industrial roadmap that will make a universal quantum computer a reality in the near future. Our goal is to make a positive impact on our digital future through quantum-enabled computing solutions for energy distribution, drug discovery, and more. Quobly, based in Grenoble, France, is a spinoff of the CEA, a major RTO, and CNRS, a leading center for academic research. The company will continue to develop a silicon spin qubit technology nurtured over two decades of research partnerships between these organizations. In simple terms, our research led to a major advance: turning transistors into quality quantum bits. We believe that that leveraging proven semiconductor-industry technologies, processes, and manufacturing capacities in Europe is the fastest and most cost-effective way to get a universal quantum computer to the market. Europe’s semiconductor giants already know how to fabricate millions of identical objects. We now know how to apply these capabilities to qubits.
