Synchrotron radiation sources generate highly brilliant light pulses, ranging from infrared to hard X-rays, which can be used to gain deep insights into complex materials. An international team has now published an overview on synchrotron methods for the further development of quantum materials and technologies in the journal Advanced Functional Materials: Using concrete examples, they show how these unique tools can help to unlock the potential of quantum technologies such as quantum computing, overcome production barriers and pave the way for future breakthroughs.

In quantum technologies, quantum physical principles such as superposition, interference and entanglement play a decisive role in their function. Components in quantum technology can perform calculations orders of magnitude more efficiently and encrypt information (quantum computing) or deliver unprecedented measurement accuracy in sensors. However, developing such components for practical use remains challenging because quantum systems are inherently sensitive to environmental disturbances, making precise control under normal conditions difficult. To make progress in this area and identify sources of error, it is essential that the materials and devices are thoroughly characterised and better understood.

Synchrotron and FEL radiation sources provide an ideal toolkit for this purpose. The available methods include non-destructive imaging, X-ray diffraction, spectroscopy, spectromicroscopy and investigations of electronic and magnetic nanostructures.

A team from HZB has written this overview together with colleagues from universities and other European synchrotron radiation sources.

“Hitchhiker's Guide” published

The “Hitchhiker's Guide” to synchrotron and FEL light sources for quantum technology has been now printed and is available online (www.helmholtz-berlin.de/srforqt).

This brochure briefly introduces key methods and applications while offering a detailed directory of European experimental stations particularly suited for research in quantum technologies along with access modes and contacts.
