Quantum Technology

Our Services

The focus of this technology field is on the development of lasers, laser-based processes and process technology as a basis for the production of quantum materials and components, as well as design and hardware for quantum systems.

New Quantum Technology

Our lives have been changed forever by data transmitted via fiber optics and lasers, GPS systems, and computers and smartphones with compact silicon technology. However, these forms of modern communication and the Internet would not be possible without the first generation of quantum technologies.

As advances continue to be made in quantum computers and the quantum internet, a next paradigm shift is imminent, one in which previously unused physical effects can be used for novel applications. Whereas collective particle phenomena were previously in the foreground, both individual photons and quantum states can now be manipulated and controlled in a targeted manner.

In this technology sector, Fraunhofer ILT is developing new technologies and devices that take advantage of fundamental quantum physical properties. To accomplish this, however, these devices have to fulfil strict requirements upon the precision, individuality as well as compactness of system components. At the same time, solutions are required that can later be implemented on an industrial scale.

Together with top German and international researchers, Fraunhofer ILT scientists are developing a broad portfolio of systems and processes for quantum technologies. In addition to lasers and fiber modules, these include parametric photon sources and frequency converters, integrated optical components and packaging processes.

Since we cooperate closely with, among others, the chairs of Laser Technology LLT and Optical Systems Technology TOS as well as the Institute for Quantum Information at RWTH Aachen University, we can deepen our fundamental understanding of the underlying interaction effects, an understanding necessary to control of quantum states precisely. In addition, long-term collaborations exist with, among others, the Forschungszentrum Jülich or the Dutch research center QuTech.
