LuxQuanta, a deep tech company specializing in quantum cybersecurity, has closed an €8 million ($9.3 Million USD) Series A funding round. The round was led by Big Sur Ventures, with A&G as the largest investor, and included participation from GMV, Wayra, and the EIC Fund, alongside existing shareholders Corning, and GTD. This investment is bolstered by a €2.5 million ($2.9 million USD) grant from the European Investment Committee (EIC) through the EIC Accelerator program.
The funding will accelerate the international rollout of LuxQuanta’s Continuous-Variable Quantum Key Distribution (CV-QKD) technology. The company’s flagship product, NOVA LQ®, is designed to integrate into existing optical networks while offering security and scalability. Key features of the system include compliance with ETSI GS QKD 014 and SKIP interfaces, a high secret key rate (>100 kbps at 4 dB loss, 1 kbps at 16 dB), and support for point-to-point and point-to-multipoint configurations.
With this funding, LuxQuanta plans to scale production, advance research in quantum technologies and integrated photonics, and expand its commercial and technical teams. The company’s CEO, Vanesa Díaz, noted that the investment will help the company make quantum security accessible and reliable for organizations in telecommunications, government, data centers, and critical infrastructure.
