Refined joins European consortium to develop quantum internet technology
Refined Laser Systems is part of QTRAIN, a European consortium working to develop the first commercially available single photon quantum transceiver compatible with existing telecom infrastructure.
The device is designed to both send and receive data using individual photons of light, enabling communication systems with fundamentally higher security than conventional networks.
The project is supported by the EUREKA programme and brings together four specialist partners with complementary technologies:
• Ruhr University Bochum developing high quality quantum dot materials
• Refined Laser Systems providing lasers to excite the quantum dots
• Sparrow Quantum supplying deterministic single photon sources
• Single Quantum manufacturing detectors and cryogenic systems, with assembly in Delft
The consortium aims to significantly reduce the size, energy consumption, and cost of quantum communication hardware while enabling scalable deployment within existing telecom networks.
Within the project, Refined Laser Systems is developing laser sources optimized for efficient quantum dot excitation in the telecom O band. The first improved prototype is expected in summer 2026 as part of the roadmap toward a complete quantum transceiver system by 2027.
The project highlights how advanced laser technologies developed for scientific and medical applications can also enable emerging fields such as quantum communication.
