Fraunhofer IAF establishes an application laboratory for quantum sensors


In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.

The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers from six Fraunhofer institutes, in collaboration with the universities of Stuttgart and Boulder, Colorado (USA), are developing quantum sensors for the highly sensitive detection of magnetic fields.

In the application laboratory, a quantum magnetometer is being set up that can measure the smallest currents in semiconductor circuits.

Fraunhofer IAF

In order to strengthen the transfer of these quantum sensors into industrial and medical technology applications, Fraunhofer IAF will put several quantum magnetometers into operation in the new application laboratory to make them available to partners from science and industry.

Funding by the state of Baden-Württemberg and the Fraunhofer-Gesellschaft

The state of Baden-Württemberg will provide funding of one million euros for the establishment and operation of the laboratory. »We want Baden-Württemberg to play a leading role in the creation of value with quantum technologies in the future.

With its infrastructure, the new application laboratory will in particular support our industrial companies and SMEs in integrating the innovation potential of quantum sensor technology into the development of new products,« said Minister of Economic Affairs Dr. Nicole Hoffmeister-Kraut, explaining the decision.

The Fraunhofer-Gesellschaft is providing co-financing of one million euros. Prof. Reimund Neugebauer, President of the Fraunhofer-Gesellschaft, stated: »Developments in quantum sensor technology are a central factor in our competitiveness in international high-tech markets.

Of crucial importance is the fastest possible transfer of research results into applications and the market. The new application laboratory at Fraunhofer IAF will make an important contribution here to economically exploit the innovation potential of quantum sensors.«

Evaluation, comparison, use

The quantum magnetometers in the application laboratory are individually optimized for use by companies and are thus suitable for evaluating a wide range of industrial applications.

A platform for service and contract measurements will also be created so that industrial customers can compare the performance of quantum sensor technology with that of classical sensor systems.

To facilitate the use and operation of quantum sensors, software packages will be developed that can be adapted to the requirements of the respective application.

Increasing industrial demands for more accuracy

Many industrial sectors are currently experiencing rapid technological development towards ever more precise monitoring and controlling of their production. The increasing demands on accuracy and drift stability of sensor systems will require a technological leap towards quantum sensor technology in the near future.

However, research on this topic has so far been conducted within the academic framework and the quantum sensors developed have proven to be too large and not robust enough for use in innovative products. This applies to the booming semiconductor industry, for example.

»Methods used to date for measuring the smallest leakage currents in semiconductor components are very complex and expensive and are therefore only available to a very limited extent.

Quantum magnetometry now has the potential to become a standard method for the development, characterization and deviation analysis of integrated circuits,« said Dr. Helmut Angerer, Senior Manager Failure Analysis at Infineon Technologies.

Areas such as medical technology, security technology, navigation, geology and satellite-based earth observation will also benefit from a faster transfer of quantum sensor research into industrial applications.

Im Focus: Harnessing the rain for hydrovoltaics

Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. They developed a method to quantify the charge generation and additionally created a theoretical model to aid understanding. According to the scientists, the observed effect could be a source of generated power and an important building block for understanding frictional electricity.

Water drops sliding over non-conducting surfaces can be found everywhere in our lives: From the dripping of a coffee machine, to a rinse in the shower, to an...

Im Focus: Blocking the Iron Transport Could Stop Tuberculosis

The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.

One of the most devastating pathogens that lives inside human cells is Mycobacterium tuberculosis, the bacillus that causes tuberculosis. According to the...
