Quantum Technologies

Quantum computing will change our world – in science, industry, the economy, and our everyday lives.

Wolfgang Marquardt

The development and use of quantum technology is one of the most ambitious technological goals of science today. The effects on society and business are almost impossible to predict. The Helmholtz Association’s mission is to contribute to solving important and urgent social, scientific, and economic problems. Helmholtz is a driver of quantum technology research in Germany and Europe and a pioneer in science and technology. Together with partners at universities and research institutions as well as in industry, Helmholtz aspires to push forward the development of quantum technologies, from basic research to system development to application.

Helmholtz is active in the five primary areas: quantum computingquantum communicationquantum sensing, quantum materials and basic research, as well as simulation and numerical methods. In addition, Helmholtz develops, builds, and operates powerful infrastructures for researching quantum technologies. 

Quantum communication

Quantum communication allows unprecedented security for data transfer by harnessing the laws of quantum mechanics. The selection of quantum states is used to create key protocols for secure data transfer. Quantum encryption is thus not based on mathematical assumptions, but on physical laws. Quantum states are very fragile, however, and precise measurement is complicated, so transfer (within individual chips or across great distances) entails significant technical challenges.

Helmholtz is currently focusing on quantum communication systems in aerospace applications and researching fundamental questions of quantum encryption. The goal is to make worldwide quantum cryptographic connections possible in the future. The vision is a quantum communication network – a quantum Internet – in which terrestrial and space-based systems are interconnected via quantum repeaters, allowing unprecedented communication security.
