QuTech Spinout Q*Bird Rebrands to Falqon Systems to Commercialize Quantum Secure Networks

QuTech Spinout Q*Bird Rebrands to Falqon Systems to Commercialize Quantum Secure Networks Delft-based quantum communications developer Q*Bird has officially transitioned into Falqon Systems, adopting a unified corporate identity to support its expansion from hardware component manufacturing to deploying end-to-end Quantum Secure Networks (QSN). Originating as a spinout from QuTech and Delft University of Technology (TU Delft) in 2022, the company’s ownership structure, leadership team under CEO Dr. Ingrid Romijn, existing customer contracts, and technological roadmaps remain unchanged. The rebranding consolidates the company’s product matrix under the Falqon umbrella, which combines hardware devices, key lifecycle management, and network orchestration software into an integrated platform. The core architecture is built upon Measurement-Device-Independent Quantum Key Distribution (MDI-QKD). Unlike traditional point-to-point QKD protocols, MDI-QKD routes quantum signals through a central untrusted hub, eliminating detector-side channel attack vectors and allowing multi-node star topologies to share cryptographic keys without exposing raw keys at the central junction.
