Quantum Key Distribution (QKD) is becoming increasingly relevant as concerns about data security grow. Delft-based Q*Bird, in partnership with Single Quantum and Eurofiber, has been awarded a €1 million subsidy to further develop this technology. The initiative is expected to enhance digital security by integrating quantum encryption into existing infrastructure. The funding highlights the rising interest in quantum-secured networks, particularly as cyber threats evolve. The announcement was made at the 2025 Mobile World Congress in Barcelona, reflecting the significance of the project within the telecommunications industry.
Earlier efforts in quantum communication have largely focused on experimental and small-scale implementations. Various companies and research institutions have attempted to create secure quantum networks, but large-scale commercial deployment has remained limited. Q*Bird’s project builds on previous developments in Measurement-Device-Independent QKD (MDI-QKD), a method designed to eliminate vulnerabilities in current quantum cryptographic systems. This initiative represents an effort to integrate quantum security solutions into existing digital infrastructure, making them accessible to more users and organizations.
How Will the Project Strengthen Digital Security?
The subsidy will support the QUEST project, which is funded by the Kansen voor West program and the European Regional Development Fund (EFRO). The initiative seeks to establish secure QKD connections between two of Eurofiber’s primary data centers in the Randstad region. This development is expected to enhance protection against cyber threats, including those posed by future quantum computers. Q*Bird’s collaboration with Single Quantum will also advance the commercial adoption of MDI-QKD, ensuring tamper-proof communication between users.
Eurofiber, a provider of digital infrastructure in the Netherlands, Belgium, and France, aims to incorporate quantum-secured communication into its existing network. The integration of QKD into its fiber-optic infrastructure will provide businesses and public organizations with an added layer of security.
“As a provider of vital digital infrastructure, Eurofiber is working on the network’s reliability and security. This project is an important step in the development of quantum-enabled communications,” said Marc Hulzebos, Innovation Manager at Eurofiber.
What Does This Mean for Future Quantum Networks?
The project is expected to contribute to the future development of a Quantum Internet, where secure communication will be possible over long distances. Q*Bird, which was founded in 2022 as a spin-off of Delft University of Technology, is working towards integrating quantum encryption into mainstream communications. The company claims that its patented technology offers enhanced security while keeping costs manageable.
Q*Bird’s CEO, Ingrid Romijn, highlighted the company’s commitment to advancing quantum communication:
“While we are rolling out quantum communication solutions, we are enthusiastic about working towards a more transparent and better-connected digital world for our customers.”
The project will initially connect quantum-secured communication between Amsterdam and Rotterdam, setting a foundation for broader applications in other regions.
Implementing QKD in real-world infrastructure presents both technical and operational challenges. The integration of quantum technology into conventional digital communication networks requires significant investment and expertise. However, initiatives like QUEST aim to bridge this gap by demonstrating the feasibility of quantum-secured networks in commercial settings. As cyber threats grow, quantum encryption could play a crucial role in safeguarding sensitive data.
