LuxQuanta

LuxQuanta is a European quantum security company founded in 2021 and headquartered in Barcelona, Spain. It was born as a spin-off from ICFO – The Institute of Photonic Sciences, one of Europe's leading research centers in photonics and quantum technologies. The company brings together scientists, engineers, and industry experts to turn advanced quantum research into deployable security for real-world networks. Its mission is to turn cutting-edge European science into practical, scalable security that safeguards sensitive data for decades, strengthening sovereignty and trust across global critical infrastructure. LuxQuanta's core technology is Quantum Key Distribution (QKD), which uses quantum physics to generate and share encryption keys between two network nodes using light over optical fiber. Because quantum signals are extremely low-energy, any interception attempt alters the signal and makes it visible, producing an ultra-secure symmetric shared key resilient against today's and tomorrow's cryptographic threats. The company's flagship product is Nova lq®, a ready-to-deploy QKD system powered by LuxQuanta's Continuous Variable QKD (CV-QKD) technology. Nova lq® is designed for telecom networks and data centers, offering high speed, efficiency, and reach. Nova lq® differentiates itself through co-propagation in a single optical fiber, allowing the quantum signal to transmit alongside standard DWDM data channels without dedicated fiber; extended secure reach to 100 km for metropolitan communications across offices, data centers, and government networks; carrier-grade components engineered for on-premises deployment; and a compact 2U rack-mount form factor that is 50% smaller with integrated post-processing. The system targets sectors with long-lived sensitive data, including financial services, where it protects interbank settlement networks, SWIFT corridors, market data feeds, and core banking backbone links against "harvest now, decrypt later" threats. LuxQuanta positions itself as a leader in the QKD market in Europe, emphasizing innovation, leadership, trust, passion, and courage as core values. The company argues that post-quantum cryptography (PQC) migration alone does not protect the transport layer, and that a physical layer of quantum security beneath PQC stacks creates a layered, future-proof security architecture. By deploying CV-QKD at the telco POP-to-POP layer over existing fiber infrastructure, LuxQuanta aims to make quantum-safe security practical without network disruption. The company markets its solutions under the tagline "Ready. Quantum. Go."

LuxQuanta was founded in 2021 and is headquartered in Barcelona, Spain. It was established as a spin-off from ICFO – The Institute of Photonic Sciences, one of Europe's leading research centers in photonics and quantum technologies. The company was created to commercialize advanced quantum research into deployable security for real-world networks, bringing together scientists, engineers, and industry experts. From its origins, LuxQuanta focused on quantum communications and cryptographic technologies designed for the quantum era. Its mission is to turn cutting-edge European science into practical, scalable security that safeguards sensitive data for decades, strengthening sovereignty and trust across global critical infrastructure. The company has positioned itself as a European quantum security company protecting critical communications infrastructure against current and future cyber threats. LuxQuanta developed Continuous Variable QKD (CV-QKD) technology and brought to market Nova lq®, a ready-to-deploy Quantum Key Distribution system for telecom networks and data centers. Nova lq® is designed to balance efficiency, scalability, and integration, with features such as co-propagation in one optical fiber alongside standard DWDM data channels, extended secure reach to 100 km, carrier-grade components for on-premises deployment, and a compact 2U rack-mount form factor with integrated post-processing. The company has targeted sectors with long-lived sensitive data, particularly financial services, where it addresses "harvest now, decrypt later" threats to interbank settlement networks, SWIFT corridors, market data feeds, and core banking backbone links. LuxQuanta advocates deploying CV-QKD at the telco POP-to-POP layer over existing fiber infrastructure, arguing that post-quantum cryptography migration alone does not protect the transport layer and that a physical layer of quantum security beneath PQC stacks creates a layered, future-proof architecture. LuxQuanta states its ambition to lead the QKD market and unlock the potential of this technology in Europe, emphasizing values of innovation, leadership, trust, passion, and courage. The company markets its solutions under the tagline "Ready. Quantum. Go."
