While quantum research is often seen as belonging solely to the domain of physics, its influence extends into many other disciplines. We asked two scientists – the chemist Eduarda Sangiogo Gil and the biologist Jonas Ries – how quantum theory is transforming their work.

Whenever we encrypt our data, we trust that hackers cannot crack certain mathematical problems. In the age of the second quantum revolution, this assumption is being challenged. Quantum cryptography promises security based on the laws of physics.

In June 2025, an ION satellite will launch into orbit with a "Made in Austria" quantum computer on board. Developed by researchers at the University of Vienna, it will power the world's first quantum device in space. Built in record time, it boasts another remarkable feature: it requires hardly any energy to run.

An experiment shows how quantum physics challenges our idea of reality – and what it means for new technologies. Nikolai Kiesel, head of the Quantum Systems research group at the University of Vienna, explains how invisible quantum processes make our world measurable – and how this could lead to the development of new, highly sensitive sensors.

Physics seeks to describe nature with impeccable precision, yet some theories do not quite fit together. The search for missing pieces to the puzzle takes us to the fringes of science. Three researchers ‒ from quantum science, particle physics, and mathematics ‒ told us how they are working to wrest knowledge from the mysteries of the very large and the very small.

On the occasion of Anton Zeilinger’s 80th birthday in May 2025, we look back on the awarding of the Nobel Prize in Physics – a highlight of an extraordinary scientific career. A collection of videos, photos, interviews, and background information about this remarkable moment.
