QCNets researchers are participating in these projects

DFG CeTI is a cluster of excellence of the TU Dresden. The central vision is to enable people to interact in quasi-real time with cyberphysical systems (CPS) in the real or virtual world via intelligent wide area communication networks in order to enable people and machines to exchange skills and expertise globally. 

BMBF 6G-life will drive cutting-edge research for 6G communication networks with a focus on human-machine collaboration. 6G-life provides new approaches for sustainability, security, resilience and latency and will sustainably strengthen the economy and thus digital sovereignty in Germany. 

The EU Hexa-X vision is to connect human, physical, and digital worlds with a fabric of 6G key enablers. 2030 and beyond, Europe and the world will face opportunities and challenges of growth and sustainability of tremendous magnitude; proactively tackling the issues of green deal efficiency, digital inclusion and assurance of health and safety in a post-pandemic world will be key. 

The long-term ambition of the European Quantum Internet Alliance is to  build a Quantum Internet that enables quantum communication applications  between any two points on Earth. QIA will push the frontier of technology in both end nodes (trapped ion  qubits, diamond NV qubits, neutral atom qubits) and quantum repeaters  (rare-earth-based memories, atomic gases, quantum dots) and demonstrate  the first integration of both subsystems. 

The BMBF Quantum Physical Layer Service Integration (QuaPhySI) project researches quantum bridging technologies with application potential for future generations of communication networks and towards the quantum internet. For this purpose, a holistic concept for a network architecture based on Physical Layer Service Integration (PLSI) will be designed. The compatibility with 6G networks will be ensured. The concept will be made accessible and evaluated by emulating the entire quantum-classical network protocol stack. Concrete building blocks of the roadmap are Entanglement-Assisted Data Transmission (ED) and Oblivious Transfer (OT). The project addresses secure and efficient quantum-classical communication networks, also considering quantum-classical error-correcting procedures for reliability. 

The BMBF Quantum Wireless Campus Network (QD-CamNetz) project aims at demonstrating the first 5G quantum campus network. Quantum technologies will be seamlessly integrated into the existing 5G campus network to achieve unprecedented resilience and time synchronization, which are the pillars of future Industry 4.0, tactile internet and future 6G networks. To this end, quantum routers compatible with existing communication infrastructure will be developed and realized for use outside the laboratory. For this purpose, on the one hand, the entire quantum protocol stack will be researched and developed, which not only regulates the communication between the quantum routers, but also provides functions for applications, for example. On the other hand, the associated novel network architecture must also be developed and implemented. The result is a test platform for testing real industrial application examples.

The BMBF project Quantum Internet of Things (QUIET) aims to develop a hybrid quantum-conventional communication network. In the interaction of distributed quantum states and conventional transmission, (quantum) sensors are to be networked. In this way, the performance and security of the network will be significantly increased. All layers of the network, from the physical layer to network protocols, will be considered. In the project, leading research groups from the fields of quantum communication and network technology are working intensively with companies from the telecommunications sector with the "Quantum Communication Innovation Hub".

The BMBF project "6G-Quantum Security (6G-QuaS)" aims to develop a hybrid quantum-classical wired industrial network. Here, the quantum information is to be stored continuously in the phase and amplitude of the light and not, as is common in current research, discretely in its polarization. This should result in significantly lower latency times and greater resilience against attacks while maintaining the same level of security. The project will develop the necessary protocols as well as a demonstrator.
