Abhörsicher durch Quanten

Wie schützt man Daten, wenn Quantencomputer die heutige Verschlüsselung knacken könnten? Forschende der TU Darmstadt haben ein Netzwerk entwickelt und in Kooperation mit der Deutschen Telekom Technik GmbH außerhalb des Labors installiert, das Quantenphysik für abhörsichere Kommunikation nutzbar macht. Das „Darmstadt Quantum Local Area Network“ (DaQLAN) wird seit über einem Jahr felderprobt. Am 12. September 2025 ist es erstmals öffentlich vorgestellt worden.

Festakt am Institut für Angewandte Physik

Die Deutsche Physikalische Gesellschaft (DPG) hat das Institut für Angewandte Physik (IAP) der TU Darmstadt als offiziellen „Quantenort“ im Jubiläumsjahr Quantum 2025 ausgezeichnet. Damit würdigt sie die internationale Spitzenforschung des IAP im Bereich der Quantenphysik und -technologien sowie das Engagement in der Lehre, etwa mit dem neuen Studienschwerpunkt „Quantentechnologie“. Die Auszeichnung wurde heute am Institut in einem Festakt mit Anbringung der zugehörigen Gebäudeplakette gemeinsam mit Vertreter:innen aus Forschung, Präsidium und Presse gefeiert.

Neu bei uns am Fachbereich im IAP | AG Halfmann

Ein Abend für alle, die neugierig sind auf die Quantenwelt oder einfach Lust auf eine besondere Filmvorstellung auf dem Campus der Technischen Universität Darmstadt haben.

Am 26. April 2025 hieß es im Großen Physikhörsaal der TU Darmstadt wieder: Entdecken, Staunen, Mitmachen!

Über 150 Kinder und Erwachsene verfolgten gespannt die Kindervorlesung „Faszination Licht“ mit Prof. Markus Gräfe, der das Publikum mit einer Mischung aus Experimenten, anschaulichen Erklärungen und viel Interaktion begeisterte.

Eine Woche voller Neugier, Entdeckungen & Physik!

Was für eine großartige Woche! Gemeinsam mit 25 Mädchen der Klassen 5 bis 7 haben wir im Rahmen des TUdiscover-Girls’ Camps des Fachbereichs Physik experimentiert, gefragt, geforscht – und vor allem: ganz viel gestaunt!

Samstag, 26.04.2025 | 10:00 Uhr | S2|06 Raum 030 (Großer Physikhörsaal)

Kindervorlesung mit spannenden Experimenten, veranstaltet vom Fachbereich Physik | TU Darmstadt. Die Veranstaltung gibt einen Ausblick auf die nächste TUdiscover-Woche 2026 mit dem Thema „Faszination Licht“.

TU researchers have developed and tested a novel technology for even more precise quantum sensors

UNESCO's International Year of Quantum Science and Technology begins with a success for TU researchers at the Institute of Applied Physics: Physical Review Research publishes results of their research on dichroic mirror pulses. These act like velocity-selective traffic controllers for atoms by directing the particles with correct velocity towards detection while letting run troublemakers into the void.

Publication by TU researchers in the renowned journal 'Nature Communications'

An international consortium including the Theoretical Quantum Optics working group led by Professor Enno Giese (Department of Physics at TU Darmstadt) has experimentally realised quantum sensors for the first time on the International Space Station ISS at NASA's Cold Atom Laboratory. The scientists have now published their research results in ‘Nature Communications’.

Publication by TU Darmstadt researchers in renowned journal “Science Advances”

In an amazing phenomenon of quantum physics known as tunneling, particles appear to move faster than the speed of light. However, physicists from Darmstadt believe that the time it takes for particles to tunnel has been measured incorrectly until now. They propose a new method to stop the speed of quantum particles.

Publications in special issue of AVS Quantum Science

A new record for atom-based quantum computers

Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers at TU Darmstadt have recently taken a decisive step towards achieving this goal. The results of their research have now been published in a prestigious publication.

Scientists at TU Darmstadt extend research on quantum computing to new dimension

December of each year, OPTICA, the U.S. optical society, selects scientific breakthroughs of particular interest to the broad optics community that have emerged over the past year. In this year, research conducted in the group of Prof. Gerhard Birkl at the Institute of Applied Physics at Technische Universität Darmstadt has been highlighted in this exclusive list. The special issue “Optics in 2023” of the journal „Optics & Photonics News” (OPN) reports on work conducted by Malte Schlosser, Dominik Schäffner, and their colleagues, towards advancing unique architectures for quantum computing and quantum simulation.

Research of the Experimental Solid State Quantum Optics Group

Quantum physics enables a new form of imaging that could make cancer diagnostics more precise. Physicists from Darmstadt, Jena and Barcelona have made quantum imaging more resilient to noise which may pave the way for practical applications such as in medicine.

Publication in Physical Review Letters

Quantum computers might be able to crack currently unsolvable tasks, but it is not easy to expand them to the necessary size. A new technique from a team of Darmstadt physicists could overcome this hurdle.

TU research team works on new tool for cancer diagnostics

Quantum imaging enables insights into previously invisible areas. Can tumour diagnostics also benefit from this? The TU Darmstadt, which has special expertise in quantum optics, is now investigating this question together with eight partners. The Quancer research project has a budget of 6.7 million euros and is being funded with 5.6 million euros in the framework programme “Quantum Technologies – from basic research to market” by the Federal Ministry of Education and Research (BMBF).

Previously unachieved spectral brightness

In cooperation with researchers from Taiwan and Ukraine, a physics team from TU Darmstadt has achieved an important success in quantum optics. The scientists succeeded in demonstrating a quantum light source of previously unattained spectral brightness per pump power. Their results have now been published in the scientific journal “Quantum Science & Technology”.

Researchers at TU Darmstadt are developing an anti-eavesdropping quantum network

While quantum computers offer many novel possibilities, they also pose a threat to internet security since these supercomputers make common encryption methods vulnerable. Based on the so-called quantum key distribution, researchers at TU Darmstadt have developed a new, tap-proof communication network. Their results have now been presented in the renowned journal “PRX Quantum”.

TU Darmstadt project paves the way for powerful quantum computers

A physics research group at the TU Darmstadt, which is being funded with 3.3 million euros as part of the federal “Quantum Technologies” program, is providing new impetus by combining state-of-the-art optical technology techniques with the most advanced methods of quantum optics, which facilitate scalable manipulation of quantum states.

Developing high-performance computers using qubits

Theoretical physicist Vladimir M. Stojanović took a circuitous route to his research on quantum computers. He is now presenting findings that could provide decisive impetus to this field of research.
