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.
With further advances in quantum computers and the quantum internet, a next paradigm shift is imminent, where previously unused physical effects can be utilized for novel applications. Whereas collective particle phenomena were previously in the foreground, individual photons and quantum states can now be manipulated and controlled in a targeted manner.
In this field of research, 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 technologies.
