LuxQuanta, a deep-tech company specializing in quantum cybersecurity, closed an €8 million ($9.3 million) series A funding round. The funding will allow the company to scale production, advance R&D in quantum technologies and integrated, expand its commercial, technical, and operational teams, and accelerate international market expansion.

With headquarters in Barcelona and a business unit in Madrid, LuxQuanta plans to relocate to larger facilities, ramp up production, and selectively expand into new markets in Europe and beyond. The funding will also fuel advancements in integrated photonics, positioning LuxQuanta to meet the growing global demand for quantum-safe solutions, it said. According to the company, its continuous-variable quantum key distribution (CV-QKD) technology is poised to democratize quantum-safe communications, delivering robust, scalable, and accessible solutions for telecommunications, governments, data centers, financial institutions, critical infrastructures and industrial and energy sectors. LuxQuanta launched the second generation of its flagship product, NOVA LQ, in March. The product is designed to ease the transition to quantum-safe infrastructure by integrating seamlessly into existing optical networks while offering unmatched security and scalability. The technology implements the rigorously tested Gaussian-modulated coherent-state (GMCS) CV-QKD protocol, proven secure against collective attacks under finite-size conditions. It supports point-to-point (P2P) and point-to-multipoint (P2MP) configurations, halving costs for network expansion while maintaining security, according to the company. LuxQuanta was founded in May 2021 as a spin-off from ICFO, the Barcelona-based R&D center focused on photonic sciences.
