- The upgraded system extends CV-QKD’s range to 100 km and 20 dB, supports multi-receiver network configurations, and features interchangeable receivers for increased efficiency and reduced costs.
- Designed as a plug-and-play solution, NOVA LQ® integrates with existing infrastructure, addressing growing cybersecurity threats while ensuring cost-effective implementation of quantum cryptography.
LuxQuanta, a leader in quantum cryptography, has announced the launch of the second generation of its NOVA LQ® quantum key distribution (QKD) system at Quantum Europe Space (Hall 6 – Stand 6A8) within the Quantum Flagship of the Mobile World Congress. This release, two years after the initial version, advances Continuous Variable Quantum Key Distribution (CV-QKD) technology, enhancing security for businesses and organizations preparing for quantum-era encryption.
The upgraded NOVA LQ® system extends the maximum range of CV-QKD technology to 100 km and 20 decibels (dB), more than doubling the previous version’s capabilities. It supports flexible network configurations with multi-receiver connectivity, enabling ring and star topologies where a single transmitter can connect to multiple receivers. Additionally, its receivers are interchangeable rather than fixed to specific transmitters, increasing network efficiency and reducing costs.
Designed as a fully integrated plug-and-play solution, NOVA LQ® features a compact design and a high key rate that supports multiple applications from a single connection. It is compatible with leading key management systems (KMS) and encryptors, ensuring seamless integration with existing network infrastructure. QKD technology leverages quantum physics to generate and distribute symmetric cryptographic keys securely, eliminating reliance on mathematical algorithms.
“LuxQuanta was created to develop a distinctive QKD technology, known as CV-QKD, that offers unique capabilities,” said Vanesa Díaz, CEO of LuxQuanta. “Today we have pushed its limits, 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 anticipating the post-quantum era. Our R&D team has made this possible by bringing to market a solution that represents the next generation of quantum cryptography.”
As quantum computing and artificial intelligence advance, concerns over the security of current cryptographic systems are growing. The NOVA LQ® system is designed to address these emerging threats while reducing operational and implementation costs. “QKD technology continues to establish itself as essential to safeguarding digital information, and the industry has a clear vision of what is needed to facilitate its implementation, with cost-effectiveness as its central axis. Our second generation of NOVA LQ® is a clear demonstration of our commitment to meet this need,” Díaz added.
