New collaborative project to explore technologies and demonstrator systems for quantum repeaters
Quantum networks have become increasingly important in research in recent years. They could not only enhance the security of critical infrastructure, but also open up new applications – ranging from the secure interconnection of quantum computers to a future quantum internet. Such networks are based on what are known as quantum repeaters. A new collaborative project now aims to further develop technologies and demonstrators for quantum repeaters and test them in operation.
Project explores the best of both worlds: quantum computers and classical computers
Quantum computers can do some things better than classical computers, but there are still many things they cannot do. Scientists at Saarland University are now working with industry partners BMW, Infineon and the quantum computing start-up planqc to bring the two worlds together. A quantum computer is intended to help classical computers tackle highly complex optimisation challenges encountered in everyday industrial practice. The project is being funded with €2.3 million from the Federal Ministry of Education and Research.
Milestone on the road to the ‘quantum internet’ - published in Nature Communications
Researchers at the University of Stuttgart have teleported quanta between photons from two distant light sources, achieving a decisive breakthrough in the development of quantum repeaters. Instrumental for the success of the experiment were “quantum frequency converters”, which compensate residual frequency differences between the photons. These were developed by a team led by Christoph Becher, Professor of Quantum Optics at Saarland University. Researchers from Dresden were also involved.
Science: Mathematicians discover phenomenon that could make quantum technology more efficient
An international team of researchers, including mathematician Jonas Haferkamp from Saarland University, has discovered a new phenomenon in the world of quantum physics. States that appear to be purely random, without actually being so, are generated much faster than previously thought. This could significantly improve many quantum physics applications. Due to their fundamental importance, the findings were published in the journal Science.
Quantum crystals can organize themselves like flocks of birds and suddenly disintegrate again
Self-organization is a fundamental natural phenomenon that can be observed both on a small scale under a microscope and in outer space. It is omnipresent and can be seen impressively in flocks of birds, for example. In the quantum realm, self-organization is still largely unexplored. Research teams at ETH Zurich and Saarland University have now been able to reveal the mechanisms that lead to the self-organization of a quantum gas in the form of a crystal and to its decay.

Transformation fund enables new center for quantum technologies
The Saarland state government is sending a powerful signal in support of science, innovation, and economic renewal: with over €53 million from the Transformation Fund, the state is funding the establishment of a Center for Quantum Technologies (QuTe) at Saarland University—one of the largest single funding measures in the field of higher education and science that Saarland has ever initiated.
Kick-off event for the Center for Quantum Technologies (QuTe)
When: Tuesday, March 31, 4:00 p.m. to 7:00 p.m.
Where: Innovation Center on the Saarbrücken campus
Lecture on the 2025 Nobel Prize in Physics: Frank Wilhelm-Mauch provides insight into the world of quantum computers
On Monday, January 19, one of the leading experts in the development of quantum computers will explain how Nobel Prize winners in Physics John Clarke, Michel H. Devoret, and John M. Martinis paved the way for the supercomputers of the future, even though their original intention was to conduct basic research: All interested parties are cordially invited to attend Frank Wilhelm-Mauch's lecture, which will be held at 6 p.m. in Building E2 5, Lecture Hall 1, on the Saarbrücken campus.
The Center for Quantum Technologies (QuTe) is supported by the Transformation Program Research and Knowledge Transfer Saar.
