LuxQuanta launches second generation of QKD system, NOVA LQ®, at MWC 2025

Barcelona, Spain, 5th March 2025 - LuxQuanta, a European pioneer in Quantum Cryptography, has today announced the launch of the second generation of its Quantum Key Distribution system, NOVA LQ®, at Mobile World Congress 2025.

Launching two years after the product's first iteration, the new generation of NOVA LQ® pushes the boundaries of Continuous Variable Quantum Key Distribution (CV-QKD) technology. This new product enables QKD operation alongside classical data in existing optical fiber infrastructure. NOVA LQ® eases the transition to quantum-safe cybersecurity.

QKD leverages the principles of quantum physics to securely generate and distribute symmetric cryptographic keys between two locations without relying on mathematical algorithms. The quantum signal, transmitted through standard optical fibre, carries the information needed to generate cryptographic keys, which are secured by the laws of quantum physics.

The emergence of powerful quantum computers and artificial intelligence (AI) are increasing concerns over the security and reliability of current cryptographic systems, which today protect all communications, including highly sensitive data across all industries. As quantum-safe security alternatives become increasingly urgent, organisations and institutions are preparing for present and future threats. NOVA LQ® aims to ease this transition, designed to reduce operational and deployment costs while ensuring network scalability.

Built with carrier-grade components and capable of using lit optical fibres, NOVA LQ® can transmit the quantum signal along classical data traffic to ensure full compatibility with existing optical networks. This feature removes the need to use dedicated dark fibers and  optimises optical network infrastructure, which is the most expensive resource.

Combining speed and efficiency, the second generation of NOVA LQ® pushes the maximum reach of CV-QKD technology to provide 100km (20dB) of maximum reach, more than 200% improvement over the previous generation.

NOVA LQ® also enables flexible network configuration with multi-receiver connectivity for Ring and Star-type network topologies, connecting a single transmitter with multiple receivers. In addition, the receivers are interchangeable, unpaired with the transmitters, increasing network flexibility and efficiency while optimising costs.

A fully embedded, plug-and-play solution, the new generation of NOVA LQ® features a compact 2U design, reducing its form factor. This, combined with the high key rate that allows the feeding of multiple applications with a single connection, optimises the space at customer premises by reducing its footprint.

     Fully compatible with leading Key Management Systems (KMS) and encryptors, NOVA LQ® provides interoperability that seamlessly integrates with legacy and quantum-safe network infrastructure within the user’s own network infrastructure. These features combine to provide increased performance and reliability with cost-effective deployment.

Vanesa Diaz, CEO, LuxQuanta, said: “QKD continues to establish itself as an essential technology for safeguarding our digital information, and the industry has a clear vision of what is needed to facilitate its deployment with cost-effectiveness at its core.

Our second generation of NOVA LQ® is a clear demonstration of our commitment to meeting this need. From the start, LuxQuanta has been developing a distinctive QKD technology known as CV-QKD, offering unique capabilities. Today, we have pushed its limits even further, delivering unprecedented performance while ensuring a cost-effective solution.

Our goal is to shape the future of QKD, paving the way for widespread adoption, and our R&D team has made it possible by bringing to market a solution that represents the next generation of quantum cryptography.”
