QUIET (“Quantum Internet of Things”) is a joint project funded by the BMBF with the aim of developing a hybrid quantum-conventional – i.e. based on both quantum technologies and classic communication technology – communication network.
The digitization of our society is progressing more and more. An ever-increasing number of devices have network connections, which means that they can exchange information with one another and thus respond optimally to user requirements.
This “Internet of Things” and the associated increase in the exchange of our data places increasing demands on the security of our communication networks. New technologies are required to meet these demands. Previous network-enabled devices regularly exchange data with each other. Currently, however, they encrypt your data based on cryptographic protocols, which are based exclusively on the finite performance of today’s computers. This limits the maximum possible data rates and data security. The use of quantum states in a quantum communication network offers a novel solution. Here, data is encrypted and exchanged with each other using quantum states of light based on fundamental laws of nature. This will allow messages to be transmitted securely and quickly in the future.
GOALS AND PROCEDURE
The joint 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. This should significantly increase the performance and security of the network. All levels of the network are considered, from the physical layer to network protocols. 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 “Innovation Hub of Quantum Communication”.
DEUTSCHE TELEKOM AG, T‑LABS
The T‑Labs are the research and development department of Deutsche Telekom AG (DTAG), which focuses on implementing new technology trends and delivering tangible results for Deutsche Telekom’s innovation portfolio. Current research areas at T‑Labs include: Future Networks, Spatial Computing, Network Security & Digital Twin and decentralized systems. Co-Research is the team’s main task with the vision of achieving the best possible customer experience and researching disruptive technologies for future telecom infrastructures. From the Berlin location, T‑Labs works with the world’s leading universities, start-ups, investors, research institutes and industrial innovation institutions to shape the future of communication services together.
In the QUIET project DTAG focuses both on the end-to-end functionality of an integrated quantum IoT system and on architectural and operational aspects that represent the skills to be provided in a cost- and time-optimized way. In particular, DTAG would like to pursue the potential for innovation in the “security-by-design” dimension, i.e. robustly providing security and privacy from the sensor to the backend and back with the appropriate use of quantum resources. Opportunities for improving performance in terms of data throughput and energy efficiency should also be examined more closely along the IoT end-to-end view.

Prof. Dr.-Ing. Dr. rer. nat. Holger Boche (LTI):
The LTI working group at TUM has been working on the development of quantum communication since 2010. An important building block for a future technological use of quantum systems for information transmission is a mathematically developed and operationally meaningful quantum information theory. As in the case of classical information, an asymptotic theory in the sense of Shannon is a suitable framework. The main focus of the research work is a quantitative understanding of the role of various communication resources of a classical and quantum-theoretical nature and their mutual relationships with one another.
