EU Funds QKD Certification Push With QUARTERNEXT

July 6, 2026 — A six-member European consortium called QUARTERNEXT launched with a four-year mandate and an EU budget line behind it. Its mission: take continuous-variable quantum key distribution (CV-QKD) from laboratory demonstrations to certified, industrial-grade hardware fit for deployment across Europe’s critical infrastructure.

The bottom line for security leaders: this project will not change what you should be doing right now (migrating to post-quantum cryptography remains the priority), but it will change the medium-term planning picture. If QUARTERNEXT delivers certified QKD products through Europe’s Nostradamus certification infrastructure, enterprise CISOs in EU-regulated sectors may face QKD as a compliance and procurement fact within five to seven years, regardless of their personal assessment of the technology.

Funded under the Digital Europe Programme’s IRIS² QCI call (DIGITAL-IRIS2-2025-QCI-01), QUARTERNEXT brings together six organizations across three countries. Luxquanta, a Barcelona-based CV-QKD hardware developer, coordinates the consortium. The remaining partners are Quside (quantum random number generators, Spain), Chilas (tunable narrow-linewidth photonic laser sources, Netherlands), fragmentiX (quantum-age secret-sharing appliances, Austria), Telefónica (telecommunications operator, Spain), and the Austrian Institute of Technology (AIT) (Austria’s largest research and technology organization).

The project’s 48-month roadmap targets four deliverables. First, compact CV-QKD transmitter and receiver units integrating narrow-linewidth lasers and high-performance quantum random number generators. Second, a software-defined key management system for scalable distribution across complex networks. Third, a secret-sharing appliance with higher data rates and standa…
