Quantum Technologies
Quantum technology represents one of the key technologies of the 21st century. The expertise of our research group in this context includes micro- and nanotechnologically fabricated quantum systems and optical systems, among others, for the fields of quantum metrology and geodesy. In this context, polymer-based substrate materials and the associated relevant processes are also increasingly being used. The focus here is not only basic research but also on the transition to commercial products. The path from laboratory operation to mobile applications in the field or on board of aircrafts or satellites requires miniaturization of the overall system. The vision is to evolve from a micro-electro-mechanical system (MEMS) to a micro-quantum system (MQS) that combines all the functions needed to operate a quantum system. In addition to the core component (e.g. atom chip), this also includes all peripheral systems.
Modern manufacturing requires innovative solutions to meet increasing demands. To this end, we develop and integrate microtechnological components that are specifically tailored to the respective application. Our expertise ranges from process development to quality assurance. One focus area is the manufacture of thin-film sensors for the precise measurement of variables such as strain and temperature. We also conduct research into microsystems for biomedical applications and investigate friction, wear and lubrication conditions at the micro- and nanomechanical level in microtribology. To ensure optimum electrical and mechanical contact, we develop customised assembly and connection technologies as part of system integration. Another focus is the use of artificial intelligence. We develop algorithms that recognise patterns in sensor data, for example, in order to create a comprehensive understanding of processes and open up new possibilities for control and optimisation.
Diamond has a number of unique material properties such as: excellent biocompatibility, hardness, wear resistance, transparency, chemical stability, and thermal conductivity. In addition, diamond is gaining more and more importance in fundamental research as a functional material in MOEMS, MEMS, and NEMS, with tailored optical and electrical properties. Applications include biosensors, transparent electrodes, photochemical systems, and quantum optical devices. An interdisciplinary alliance (HARD) of outstanding institutes, scientists, and researchers has been formed at the LUH and the MHH, which have a high-quality contribution in application-oriented research on diamond-functionalized devices and systems. The use of diamond will strengthen the existing research priorities and the coordinated research projects through a special infrastructure project, so that future innovative leaps are secured through the integration of diamond as a functional material in the participating research disciplines. This will be achieved through the procurement and commissioning of a production line for the manufacture, structuring, functionalization and integration of diamond coatings, which will enable higher performance and novel functions in existing and future systems.
