Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.
Neben spannenden Vorträgen über «Geheimnisvolle Gravitation» sowie über «Supraleitung» wurde auch an der diesjährigen Ausgabe ein Experimente-Park organisiert.
Eine Zusammenfassung der beiden Tage können Sie hier im Video geniessen.

Das Bahnunternehmen BLS und die Universität Basel gehören zu den Gewinnern des diesjährigen Energiepreises Watt d'Or, der vom Bundesamt für Energie vergeben wird. Sie erhielten die Auszeichnung für ein Modernisierungsprogramm für Schienenfahrzeuge, dank dem erheblich viel Strom eingespart werden kann. Lanciert wurde die Effizienzinitiative vom emeritierten Basler Physikprofessor Peter Oelhafen.
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal small, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
At the 558th Dies Academicus, the Emilie Louise Frey-Preis 2018 is awarded to Katharina Laubscher for her Master thesis "Universal quantum computation using a hybrid quantum double model” carried out in the group of Prof. Daniel Loss.
Currently, Katharina is an Excellence Fellow of the PhD School “Quantum Computing and Quantum Technologies” and is doing her PhD in the group of Prof. Jelena Klinovaja in the field of topological quantum computing.
In her Master thesis, Katharina showed that it is possible to build novel planar quantum codes based on the combination of two different quantum double models, and that such hybrid codes constitute a novel pathway to universal fault-tolerant quantum computation. From a purely theoretical point of view, this is an important proof of principle and a large step towards a complete understanding of the quantum double models and their potential for quantum computation. From a more practical point of view, there may be direct advantages in terms of time- and special overhead of such a hybrid model compared to other techniques that enable universal fault-tolerant quantum computation, the most prominent one being a particularly resource-intensive procedure called magic state distillation.
Bell’s theorem has been proposed to certify quantum sources and measurements in a way that is independent of the imperfections of the actual implementation. The team of Prof. Sangouard showed how Bell’s theorem can be used to certify coherent operations for the storage, processing, and transfer of quantum information. This completes the set of tools needed to certify all building blocks of a quantum computer. These results have been published in Physical Review Letters and highlight by the SNF.
Following outstanding evaluation by the tenure committee, approval by the Faculty of Natural Sciences, the Rectorate, and finally the Council of the University of Basel, Prof. Dr. Jelena Klinovaja was awarded tenure and promoted to the rank of associate professor.
Today, the European Commission launched its flagship initiative on quantum technologies. Three research groups from the Department of Physics at the University of Basel are involved. The aim of the 1 billion euro research and technology funding program is to develop radically new and powerful quantum technologies by exploiting various quantum effects.
