Opening event of the focus semester on quantum information
On Monday, 26 September 2022, the opening of the Focus Semester on Quantum Information will take place at 14:00 in the Günther Hotz Lecture Hall (building E2 2). The president of the university, Prof. Schmitt will open the event and we will have a scientific talk by Tommaso Calarco, director at the Forschungszentrum Jülich. This talk is also the first colloquium of the Jülich-Saarbrücken Graduate School.

Opening Event of the Focus Semester on Quantum Information
Wissenschaftler und Studierende aus aller Welt kommen zusammen zum Fokussemester Quanteninformation
Ab Montag, 12. September, wird die Universität des Saarlandes zum Treffpunkt des Wissenschaftsnachwuchses auf dem Gebiet der Quanteninformationstheorie: Führende Forscherinnen und Forscher werden Vorlesungen und Seminare über die Grundlagen und die aktuellen Fragen der Quanteninformation halten. Mehr als 100 Masterstudierende der Fächer Mathematik, Physik und Informatik sowie Promovierende nehmen am Programm teil. Bis 9. Dezember beschäftigen sie sich intensiv mit der Welt des Quantencomputers.
Artikel in "Nature" beschreibt Rekordverschränkung von Quantenspeichern
Forscher der LMU München und der Universität des Saarlandes haben zwei Quantenspeicher über eine 33 Kilometer lange Glasfaserverbindung miteinander verschränkt – ein Rekord und ein wichtiger Schritt hin zum Quanteninternet. Dazu haben sie heute einen Artikel in „Nature“ veröffentlicht.
Ein Netzwerk, in dem die Datenübertragung völlig sicher vor Hackerangriffen ist? Wenn es nach Physikern geht, soll genau das mit Hilfe des quantenmechanischen Phänomens der Verschränkung irgendwann Realität werden. Denn für verschränkte Teilchen gilt: Misst man Zustandseigenschaften des einen Teilchens, so kennt man automatisch auch die des anderen. Dabei spielt es keine Rolle, wie weit die verschränkten Partner voneinander entfernt sind. Eine ideale Voraussetzung, um Informationen abhörsicher über große Distanzen zu übertragen.
Focus Semester on Quantum Information
From 12 September 2022 to 9 December 2022, the Focus Semester on Quantum Information will take place at Saarland University, Saarbruecken, Germany.
The aim is to study quantum information theory from the perspectives of mathematics, physics and computer science. Here is a brief video teaser on YouTube.
We will have numerous international experts giving multidisciplinary lectures at Saarland University, accompanied by various research talks in seminars.
The program will be accessible for first year Master's students, in particular, providing an introduction to this modern field. However, also PhD students, postdocs and researchers are welcome to participate in the program.
There is free accommodation available. Application deadline: 30 April 2022.
Physicist Karin Jacobs admitted to Göttingen Academy of Sciences
Karin Jacobs, Professor of Experimental Physics at Saarland University, has been accepted as a corresponding member of the Göttingen Academy of Sciences. This honor is only bestowed on professors who have made exceptional contributions in their field. Corresponding members usually live outside northern Germany and participate more indirectly in the life of the Academy.
In addition to Karin Jacobs, her former colleague Roser Valenti was also admitted to the Academy; she is now a professor of theoretical physics at Frankfurt's Goethe University. Valenti had conducted research at Saarland University for several years at the beginning of her scientific career.
On the way to the quantum computer: federal government funds projects of Saarbrücken physicists with ten millions
Great hopes are being placed in quantum computers because they can calculate much faster and more complexly than today's supercomputers - especially in a quantum network. However, many research questions remain unresolved, such as how to avoid sources of error in quantum computing or how to use existing fiber optic networks to link quantum computers.
This is also being researched by a team of physicists at Saarland University, which is being funded in six different projects by the German Federal Ministry of Education and Research with around ten million euros.
"Smart" slime: how a single-celled organism shows that intelligent behavior can emerge from chance
Physarum polycephalum is a real smarty-pants: experiments in which the slime mold was able to reconstruct Tokyo's rail network and solve mazes have already landed it in the news. Now, a research team has used the slime mould as a model to learn from its adaptability. The mathematical model it inspired is so general that it could not only make transportation networks more efficient, but also advance artificial intelligence.
Sixth sense decoded? Researchers track down the inner compass of living creatures
How do salmon know the route to their spawning grounds? How do animals find their destination? An international research team from Oregon, Strasbourg, Oldenburg and Saarbrücken is on the trail of the inner compass of living creatures and may have deciphered the mysterious "sixth sense". The research group of Professor Uwe Hartmann from Saarland University has succeeded for the first time in making the "compass needles" of salmon visible with a microscope.
Physicists from Saarbrücken develop simulation method to better understand membrane fusion
Biological membranes are extremely complex: Not only do they consist of thousands of different types of lipids, but they also have an asymmetric structure. Saarbrücken physicists led by Prof. Jochen Hub want to find out what biological advantage this high complexity might have. Using a new computer simulation method, they have studied membrane fusions, which play a central role in many biological functions. The results could provide the first possible explanations.
They have now been published in Nature Communications.
Research alliance on quantum communication launched - 35 million euros for three years
Digitization is advancing, and at the same time the growing exchange of sensitive data needs more security. A communication network based on the laws of quantum physics is an important approach because of the physically guaranteed eavesdropping security. The joint project "Quantum Repeater.Link" (QR.X) is pursuing this goal. It is being funded for three years by the German Federal Ministry of Education and Research with around 35 million euros. It is coordinated by Christoph Becher from Saarland University.
DFG Funding Atlas 2021: Saarland University once again among the 40 universities with the strongest research performance
In the current funding ranking of the German Research Foundation (DFG), Saarland University was able to rank 39th out of a total of 225 universities and universities of applied sciences that received funding from 2017 to 2019. It should be noted that the ranking is not calculated adjusted for size, so that universities with significantly more scientists lead the third-party funding ranking.
