Barcelona-based deep-tech company LuxQuanta recently announced that it has closed a Series A funding round of €8 million, led by Big Sur Ventures and with A&G as the largest investor. New participants in the round include GMV, Wayra and the EIC Fund, alongside renewed support from existing investors Corning and GTD, and soft-financing from the European Innovation Council (EIC) via the EIC Accelerator program after a €2.5 million grant awarded in March 2024.
LuxQuanta’s mission is to industrialize and democratize Continuous-Variable Quantum Key Distribution (CV-QKD) technology, positioning the company to serve telecommunications firms, governments, data centres, financial institutions, and critical infrastructures. The funding will support scaling production, further research and development in quantum technologies and integrated photonics, expansion of commercial, technical and operational teams, and accelerated international market expansion.
The company’s flagship product, NOVA LQ, launched its second generation in March 2025 and is designed to integrate into existing optical networks, supporting both point-to-point (P2P) and point-to-multipoint (P2MP) configurations, achieving high secret key rates and operating over substantial channel losses. The technology adheres to industry standards (ETSI GS QKD 014 and SKIP) and is built for operational reliability with production-grade hardware.
Founded in May 2021 as a spin-off from the photonic R&D centre ICFO in Barcelona, LuxQuanta has already achieved multi-million-euro sales across dozens of European countries and has deployed in Asia-Pacific, Latin America, and the United States.
The participation of investors such as Big Sur Ventures, A&G, Wayra, GMV, and the EIC Fund reflects strategic confidence in LuxQuanta’s potential to set a global standard in quantum-safe infrastructure and accelerate the transition of global communications networks into the quantum era.
