"Research needs open communication"

In the field of information, we in Jülich have a special task and responsibility, since the first European exascale computer, "JUPITER", will go into operation here next year. Exascale computers are computers that will be crucial in the field of artificial intelligence (AI). "JUPITER" is a supercomputer with more than one trillion computing operations per second. Worldwide, this will be one of the first computers of its kind. This is a huge opportunity to develop so-called Large Foundational Models, large-scale machine learning models that have been trained on broad datasets and can be adapted for a variety of applications.

The exascale computer here will operate in an environment with other supercomputers and early quantum computers. We will make this computing infrastructure available not only to the scientific community, but also to a wide range of European users from industry and the public sector. Overall, I would like us in Jülich to open up our research infrastructure even more to users outside the scientific community.

You yourself have had a long research career. How did you arrive at quantum physics of all things?

There were a few encounters that had a great impact on me. At the very beginning, I studied medicine, but then changed my subject after a few highly interesting physics lectures. And for a stay abroad, the trust professor of the Studienstiftung then sent me to Imperial College in London, to a quantum optics group. There I discovered the subject for myself and wrote my diploma thesis on it. After that, I wanted to go abroad again...

...and this time I went to France, where you stayed for a long time. What fascinated you there?

In France, experimental physics and theory are much more closely linked. People always say that quantum optics is incredibly difficult and abstract, and there I was suddenly able to work on experiments that made the theory from the books visible. That appealed to me so much that I stayed connected with France.

How far along was quantum physics at that time?

When I started, atom traps were just being developed, based on opto-mechanical phenomena that could be used to trap and store atoms. There was also research on special quantum states of light. I worked on that and later specialized in quantum vacuum fluctuations and the Casimir effect. During my postdoc period, I said to myself: Everyone calculates effects of vacuum fluctuations mathematically in the abstract, but actually, one must be able to calculate them in realistic experimental situations and compare them with the measurement results. With my research, I then became part of a wave in which the topic was just beginning to develop in many other parts of the world.

Let's look again at the present: You are, after all, also the designated vice president of the Helmholtz Research Field Information. What are your plans?

The particular challenge is to combine the forward-looking topics in a clear profile for the Research Field. In doing so, we have to make sure that we define the interfaces in such a way that all the Helmholtz centers involved are well reflected in them with their respective orientation and that we create synergies and clear added value through cooperation in the Research Field. It is important to me that the development of methods in the Research Field Information is not decoupled from the applications. To this end, the Research Field is undergoing a strategy process in which I, as designated Vice President, attach importance to jointly reviewing the current strategic orientation.
