LuxQuanta has unveiled the second generation of its Quantum Key Distribution (QKD) system, NOVA LQ®, at Mobile World Congress 2025. The new system, based on Continuous Variable QKD (CV-QKD) technology, enables secure key distribution over existing optical fiber networks, eliminating the need for dedicated dark fibers and reducing deployment costs. NOVA LQ® supports transmission alongside classical data traffic, achieving a maximum reach of 100 km (20 dB), a 200% improvement over its predecessor.
The system features a compact 2U design, multi-receiver connectivity for flexible network topologies, and compatibility with leading Key Management Systems (KMS) and encryptors. These advancements optimize space, enhance network scalability, and ensure seamless integration with both legacy and quantum-safe infrastructure. LuxQuanta’s NOVA LQ® is designed to address the growing need for quantum-safe cybersecurity as quantum computing and AI pose increasing threats to classical cryptographic systems.
The second-generation NOVA LQ® demonstrates LuxQuanta’s commitment to advancing QKD technology, combining cost-effectiveness with high performance to facilitate widespread adoption. By leveraging carrier-grade components and innovative design, the system aims to redefine quantum-safe communications for governments, financial institutions, and telecom providers.
