Let's build a Quantum Secure Network together

A Quantum Secure Network (QSN) is an operational communication infrastructure that combines quantum key generation, secure key lifecycle management, network orchestration and interoperability within a unified product solution. Rather than protecting individual communication links, Quantum Secure Networks (QSN) embed security directly into the network architecture, enabling trusted connectivity across distributed environments. 

Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) is the technological foundation of Falqon® Quantum Secure Networks (QSN). It removes detector-side vulnerabilities from the QKD security model and enables secure key distribution across scalable multi-user network architectures. This makes it well suited for building resilient, operational quantum secure communication infrastructure.

With the advancement of quantum computing, organisations are preparing for the eventual arrival of Q-Day, the point at which sufficiently powerful quantum computers could compromise widely used public-key cryptography. This risk is already driving action through “Harvest Now, Decrypt Later” (HNDL), where encrypted data is collected today for potential decryption in the future. As a result, organisations are increasingly defining their quantum secure strategies and moving from evaluating individual technologies towards deploying operational quantum secure communications across networks and distributed infrastructures.

The Falqon® portfolio brings together the core technologies required to build and operate Quantum Secure Networks (QSN). The Falqon® MDI-QKD Series enables quantum key distribution across scalable network architectures, the Falqon® Key Manager manages and delivers cryptographic keys across QKD, PQC and hybrid environments and the Falqon® Domain Controller provides centralised control, configuration and monitoring of the quantum network.

Yes. Falqon® technologies are already deployed across operational quantum communication networks in Europe, including multi-site and cross-border environments. These deployments demonstrate the scalability, interoperability and operational readiness of Falqon® technology across real-world network infrastructures.
