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.

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.
Team with TU participation realises quantum sensors in space
2024/08/19
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’.
What is “time” for quantum particles?
2024/05/16
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.
