JLICH and WRZBURG, Germany, June 1, 2021 Forschungszentrum Jlich and the University of Wrzburg will together investigate the quantum phenomena of topological materials and the opportunities they present within quantum computing. The Free State of Bavaria is funding the project to the tune of 13 million.

Numerous research groups worldwide are working on the development of quantum computers. Such computers will offer numerous advantages when they are ready for application. They require very little energy and provide extremely fast computing power as well as a high level of data security.

However, a number of technical challenges still need to be overcome. To achieve further progress in this regard, Forschungszentrum Jlich and the University of Wrzburg (JMU) are strengthening their long-standing cooperation in this field.

The project partners are turning to topological insulators as a material class. Together, they aim to research and develop topological material systems that would serve as suitable components for quantum computers.

Jlich and JMU: A strong partnership

Wolfgang Marquardt, Chairman of the Board of Directors of Forschungszentrum Jlich, and then JMU President Alfred Forchel signed a cooperation agreement to that effect in March 2021.

The cooperation with Jlich provides JMU with a great opportunity, Forchel explains. We already have outstanding resources in Wrzburg in the fields of solid-state physics, semiconductor physics, and topological materials. In Forschungszentrum Jlich, we have a strong partner whose expertise complements our own very nicely. Together, we can lead the way in topological quantum computing.

Wolfgang Marquardt, Chairman of the Board of Directors of Forschungszentrum Jlich, adds: The development of highly complex technologies such as those required for quantum computing can only be successfully achieved through sharing expertise and through the cooperation of strong partners. This cooperation is an important foundation to bring together the complementary expertise of JMU and Forschungszentrum Jlich as part of a joint effort to explore the possibilities of topological materials for robust quantum computers and thus to create a hub for new, solid-state quantum innovations.

Funding from Bavaria

The Bavarian Ministry of Economic Affairs, Regional Development and Energy is providing roughly 13 million in funding to the project to investigate quantum computing on the basis of topological materials through experimental and theoretical approaches. Bavarias minister president Markus Sder had announced this investment at the end of 2019 as part of the states Hightech Agenda Bayern initiative.

Four research groups involved

Funding is to be provided to four research groups. This funding will be used to establish four young investigators groups at both research locations.

From JMU, the teams of professors Laurens Molenkamp (experimental physics) and Bjrn Trauzettel (theoretical physics) are taking part in the cooperation. Both teams aim to host young researchers from Jlich who will set up their own young investigators groups in Wrzburg. The idea behind this is as follows: The young people will act as a kind of human bridge bringing expertise from Jlich to Wrzburg and vice versa, explains Trauzettel.

At Jlich, the subsinstitutes of the Peter Grnberg Institute (PGI) specializing in the fields of solid-state physics and theoretical physics are participating, led by professors Detlev Grtzmacher (PGI-9), Stefan Tautz (PGI-3), Stefan Blgel (PGI-1), and David DiVincenzo (PGI-2). Through the continuation of the Virtual Institute for Topological Insulators, which is funded by the Helmholtz Association, synergies in research into topological insulators will now be used in closer scientific collaboration to establish a pathway towards quantum computing, says Grtzmacher to explain the high hopes being placed in this project.

Long-standing cooperation in an excellent environment

Various collaborations in the fields of physics and information technology materials have been in place between Forschungszentrum Jlich and JMU for over ten years now. In 2012, the Virtual Institute for Topological Insulators (VITI) was jointly founded by the two partners. In light of the promising developments in topological quantum computing, both parties have decided to strengthen this cooperation in the form of joint working groups.

The research collaboration operates in an outstanding environment with two clusters of excellence related to the field: Complexity and Topology in Quantum Matter (CT.QMAT) (Wrzburg-Dresden) and Matter and Light for Quantum Computing (ML4Q) (CologneAachenBonnJlich).

A Helmholtz Quantum Center is also being built at Jlich. At JMU, a new building is under construction for the Institute for Topological Insulators (ITI). The first research teams are scheduled to move into the new building as of mid-2021.
