Spanish Companies GMV and LuxQuanta join forces to strengthen Europe’s quantum-safe future

GMV, a Spanish leader in cybersecurity, space and defense, and LuxQuanta, the Spanish pioneer and world leader in quantum key distribution (QKD) technologies, have established a strategic alliance to accelerate the real-world deployment of QKD technologies and strengthen Europe’s sovereignty in quantum-safe communications. This collaboration positions Spain at the forefront of Europe’s quantum-secure communication revolution, combining GMV’s proven Key Management System (KMS) and decades of cybersecurity experience with LuxQuanta’s field-proven Continuous-Variable QKD solutions.

For QKD networks to emerge globally, the path towards commercial, scalable, and long-range quantum communication relies on the synergy between terrestrial fiber networks and the space segment. The terrestrial layer enables secure quantum key exchanges across national and metropolitan infrastructures, forming the backbone of Europe’s quantum communication ecosystem. In parallel, the satellite segment ensures that quantum-safe communications can extend beyond ground links, enabling secure connections where fibre cannot reach, across borders and overseas, through a secure space-based quantum key infrastructure. 

LuxQuanta’s QKD technology, recognized for its robustness, interoperability, cost-effective installation, and successful field deployments, provides the physical layer for generating quantum keys securely over terrestrial infrastructures. Its Continuous Variable (CV-QKD) approach enables scalable and efficient integration into existing fibre networks, positioning LuxQuanta at the forefront of Europe’s quantum communication landscape. 

GMV, on the other hand, brings extensive experience managing encryption and key management systems in space missions such as Galileo, ensuring the reliability and operational maturity of complex, distributed key infrastructures. Its space heritage, combined with its 30-year record of cybersecurity innovation, reinforces its role as a trusted European leader in secure communications.

Together, LuxQuanta’s leadership in terrestrial quantum communications and GMV’s expertise in cybersecurity and space systems converge to deliver a comprehensive, field-proven ecosystem for quantum-safe communications, bridging fibre and space segments to meet the growing demand for secure, next-generation networks.

Under this national alliance, GMV’s space systems expertise enables the design and operation of the space segment, from satellite payload integration to ground-to-orbit link management. GMV’s Key Management Solution “QuKee” ensures full lifecycle management of quantum keys across complex networks, supporting auditing, redundancy, interoperability, and integration with post-quantum cryptographic infrastructures.

At the same time, LuxQuanta’s QKD technology, built around its NOVA LQ® Continuous Variable platform, provides the quantum layer for secure key generation in the network. Its systems are interoperable, field-proven, and cost-effective, enabling seamless integration into existing telecom optical fibre infrastructures. 

Together, they aim to deliver a Spanish-engineered, European-aligned quantum communication solution ready for industrial and governmental deployment, fully aligned with European initiatives such as the European Quantum Communication Infrastructure (EuroQCI), contributing Spanish technology and expertise to the continent’s collective post-quantum resilience.
