About
LuxQuanta is a Barcelona-based quantum security startup founded in May 2021 as a spin-off from ICFO, the Institute of Photonic Sciences. The company specializes in quantum key distribution (QKD) systems and develops continuous variable QKD (CV-QKD) technology, which provides highly secure data encryption and is easier to integrate into existing optical network infrastructure. In March 2023, LuxQuanta launched NOVA LQ, a high-performing CV-QKD solution for intra-city networks. CEO Vanesa Diaz joined as business development manager in 2021 and became CEO a year later. In March 2025, the company launched Nova LQ, its second-generation CV-QKD system, at MWC 2025, reaching 100 km, a 200% improvement over its predecessor, in a 2U form factor compatible with lit fiber. Later in 2025, LuxQuanta won the 50,000 euro equity-free first prize at the Supernova All-Stars Competition during GITEX Europe 2025, placing it among Spain's top quantum computing companies. LuxQuanta also leads the QUARTER consortium, a 7 million euro European Commission project for quantum cryptography maturity and EuroQCI readiness. In October 2025, LuxQuanta closed an EUR 8M Series A led by Big Sur Ventures.
