Hybride klassisch-quantenmechanische Netzwerkarchitekturen für den Einsatz in Telekommunikationsnetzen

Hybrid classical-quantum mechanical network architectures for use in telecommunication networks.


The digitization of our everyday lives is advancing and gaining enormous importance in all areas of our society. At the same time, the demands on the telecommunications networks used for this purpose are increasing, as in the 6G mobile communications standard. Higher data rates, reduced latency and increasingly secure data transmissions are required. To meet these requirements, not only established communication technologies must be further developed, but new technologies must also be used.

The use of quantum states can significantly increase the performance of classical transmission channels by exploiting fundamental laws of nature. For this purpose, the quantum states are exchanged between the partners of a communication network via fiber optic line or directly optically over the air by free-space beam.

Goals and Methodology

The project “Quantum Physical Layer Service Integration (QuaPhySI)” aims at developing the theoretical basis of a hybrid network architecture combining quantum mechanical and classical approaches. Secure transmission protocols for resilient as well as secure communication shall be enabled. In the interaction of distributed quantum states and classical transmission, data transmission rates are to be significantly increased. The special innovation consists in the consideration of quantum communication in all layers of a network. The approach takes into account the physical implementation, the protocols for information transmission as well as the control of the network nodes. In the project, leading research groups from the fields of quantum communication as well as network technology are working intensively with companies from the telecommunications technology sectors.

Innovations and Prospects

The project will demonstrate that the potential applications of distributed quantum states go beyond secure communication and can be used to significantly improve the performance of classical transmission channels. The hybrid network architecture developed in the project thus enables the development of future-oriented technologies that combine quantum technologies with the existing telecommunications infrastructure. This is a decisive step towards the commercial implementation of quantum communication technologies in Germany as a high-tech location.

After a successful project, the results, as a basis from today’s system design to a quantum internet, will be summarized in a roadmap. The interdisciplinary, realistic description of the network architecture will provide interested parties from industry and research with an easy entry into quantum technology. In the medium term, the project will thus make an essential contribution to the development of quantum communication infrastructures and thus to the technological and digital sovereignty of Germany and Europe.
