LuxQuanta raises €8 million for quantum cybersecurity
The company plans to use the investment to expand its teams, scale production, and advance research in integrated photonics – a key technology for developing scalable, quantum-safe solutions
LuxQuanta, a spinoff of ICFO focusing on quantum cybersecurity, has announced the closing of its €8 million Series A funding round. Led by Big Sur Ventures, and with support of A&G as the main investor, the round also includes new investors GMV, Wayra, and the EIC Fund, alongside renewed commitments from existing investors Corning and GTD. The investment is further bolstered by the soft financing from the European Investment Committee (EIC) through the EIC Accelerator programme, following the €2.5 million grant awarded to LuxQuanta in March 2024.
The company plans to use the funding to scale production, advance research and development in quantum technologies and integrated photonics, expand its commercial, technical, and operational teams, and accelerate international market expansion.
The rise of quantum computing poses a significant risk to current encryption systems, but transitioning to quantum-safe infrastructures is a complex, long-term process. If public and private entities want to keep confidential data protected, immediate action is necessary.
LuxQuanta says its continuous-variable quantum key distribution (CV-QKD) technology is poised to democratise quantum-safe communications, delivering robust, scalable, and accessible solutions for telecommunications, governments, datacentres, financial institutions, critical infrastructures, and industrial and energy sectors.
The company’s flagship product NOVA LQ, launched in its second generation in March 2025, is designed to integrate seamlessly into existing optical networks while offering unmatched security and scalability. According to LuxQuanta, the product also offers high secret key rates, standards-based interoperability, and operational reliability.
“This Series A funding is a powerful validation of our vision to safeguard global communications in the quantum era,” said Vanesa Díaz, CEO of LuxQuanta. “With this investment, we will scale our operations, enhance our technology, and expand our global footprint. The journey to quantum-safe networks is critical, and it starts now. We’re committed to making quantum security accessible and reliable for organisations worldwide.”
Ismael Almazán, partner at Big Sur Ventures, commented: “LuxQuanta’s proven CV-QKD technology and successful deployments position it as a leader in quantum cybersecurity. Their focus on integrated photonics is a game-changer, and we’re thrilled to support their mission to set a global standard for quantum-safe infrastructure.”
LuxQuanta is headquartered in Barcelona with a business unit in Madrid. The company 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, LuxQuanta adds, a key technology for reducing costs and enhancing scalability to meet the growing global demand for quantum-safe solutions.
