Quandela is France's leading photonic quantum computing company, spun out of the Centre for Nanoscience and Nanotechnology (CNRS). It builds full-stack photonic quantum computers around its high-brightness single-photon sources — a core component it also sells to labs worldwide — and operates cloud-accessible photonic QPUs, with on-premises systems delivered to OVHcloud and European HPC centers.
Quandela is one of five companies in France's €500M PROQCIMA program targeting a 128-logical-qubit fault-tolerant demonstrator by 2030. A partnership with OVHcloud is making its processors available through sovereign European cloud infrastructure.
