Overview
The Q-net-Q project not only focuses on integrating quantum key distribution (QKD) into existing ICT networks, but also significantly advances scientific research and development in this forward-looking field. Our approach combines theoretical analysis with practical testing in real-world test fields to push the boundaries of quantum communication and open up new applications.
Scientific goals and expansion of protocols
Beyond pure QKD, we are investigating the implementation of additional quantum protocols in our test fields as part of Q-net-Q. Promising candidates include coin flipping, bit commitment, oblivious transfer, and digital signatures. The goal is to identify the necessary hardware and software adaptations to create a more agile test field that can handle a wider range of practical tasks. This research is crucial to demonstrate the versatility and applicability of quantum communication beyond pure key distribution.
Comprehensive security analysis and certification
A central pillar of Q-net-Q is the comprehensive security analysis of integrated QKD hardware from partners such as FhG HHI and IOF. We are investigating how these systems can be integrated into existing communication networks from a security perspective. A detailed security analysis from an attacker's perspective is of utmost importance. The insights gained are directly incorporated into the derivation of improvements and hardening of potential products to facilitate subsequent IT security certification. This ensures that the developed solutions meet the highest security standards.
Software development: Building blocks for quantum communication
Software development plays a crucial role in the integration and operation of quantum communication systems. In the Q-net-Q project, we focus on developing robust and flexible software solutions that enable technology transfer from research to application.
Infrastructure: The physical basis of quantum security
The physical infrastructure forms the backbone for research and implementation of quantum communication. Q-net-Q attaches great importance to the development and adaptation of infrastructure components in order to maximize the performance and reliability of quantum key distribution.
Technology transfer and training
The exploitation of research results focuses on two main areas: teaching and technological sovereignty in the field of quantum technologies. The project offers a unique opportunity to collect data in a live test field and prepare it for academic purposes. This data will be used to improve research on the coexistence of quantum technology solutions with existing networks. The QuNetSim (TUM) software is used to systematically improve the training of future engineers and researchers in quantum technology.
Quantum scientists, ICT administrators, and users from various disciplines will be given the opportunity to perform interoperability evaluations of the performance and stability of various quantum sources and detectors. In addition, new methods for analyzing interactions between optical ICT and quantum components and for the cost-efficient integration of quantum communication protocols will be researched. The interdisciplinary expertise of the network partners creates optimal conditions for the successful deployment of photon-based quantum transmission methods, their technical operation on existing ICT infrastructures, open and flexible experimentation and analysis options, and the assurance of high data security and privacy standards.
Contribution to the EuroQCI initiative
Through close and continuous exchange with the partners of the EuroQCI initiative, we ensure that the research results of Q-net-Q flow directly into the development of a Europe-wide quantum communication infrastructure. This not only strengthens Germany's technological sovereignty, but also makes a decisive contribution to Europe's digital security.
