Departement of physics heads NCCR "SPIN" for development of silicon-based quantum computer

This morning, Federal Councilor Guy Parmelin announced six new National Centers of Competence in Research (NCCR), two of which are directed by the University of Basel: the NCCR “AntiResist”, led by Professor Christoph Dehio from the Biozentrum, and the NCCR “SPIN”, led by Professor Richard J. Warburton of the Department of Physics, in collaboration with IBM Research – Zurich.

 

Researchers around the world are looking for suitable ways to develop a quantum computer. At present, there are a number of approaches for the building blocks that could make up the supercomputer of the future. The realization of a quantum computer that can cope with previously unsolved tasks of high practical importance poses an immense challenge with every approach. The main problem is the limited scalability of existing systems.

 

This is where the NCCR "SPIN: Spin-Qubits in Silicon" comes in. The aim is to develop an exceptionally scalable technology that will enable the construction of a universally usable quantum computer. Prof. Dr. Richard J. Warburton and his team are focusing on the semiconductor silicon, which has proven itself in industry for decades. They are convinced that silicon technology is extremely promising for enabling the on-chip integration of billions of devices. This would lead to particularly powerful quantum computers.

Patrick Maletinsky receives ERC Consolidator Grant

Prof. Patrick Maletinsky will study atomically thin magnetic systems, with the help of novel quantum sensors.The so-called Van der Waals magnets have only recently been discovered, but already constitute a very active field of research. The quantum sensors developed in Basel, which will be used in this project, form a central pillar of the emerging field of quantum technologies and will allow new insights into Van der Waals materials. The aim is to bring the atomically thin magnets closer to possible applications in spintronics.

 

Patrick Maletinsky was appointed assistant professor with tenure-track in experimental physics at the University of Basel in 2012 and promoted to associate professor in 2017.

A cavity leads to a strong interaction between light and matter

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.

FET-OPEN grant for topological states in germanium nanowires

Limited scalability and the high sensitivity of qubits as building blocks for the quantum computer are still in the way of the ‘super computer’s’ big breakthrough. Researchers of the University of Twente, together with colleagues from Austria, Switzerland and the Netherlands may have found a promising solution to address these challenges. They have been awarded a 3.1 million euro financial contribution from the EU’s Future and Emerging Technologies (FET) programme.

How to control friction in topological insulators

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report in the scientific journal Nature Materials.

Machine learning at the quantum lab

The electron spin of individual electrons in quantum dots could serve as the smallest information unit of a quantum computer. Scientists from the Universities of Oxford, Basel and Lancaster have developed an algorithm that can be used to measure quantum dots automatically. Writing in the Nature-family journal npj Quantum Information, they describe how they can speed up this hugely time-consuming process by a factor of four with the help of machine learning. Their approach to the automatic measurement and control of qubits therefore represents a key step toward their large-scale application.
