New dynamics in the system
In addition to complexity and topology, dynamics in quantum systems is now the third focus for ctd.qmat, which will shape all research areas of the Cluster of Excellence. “Quantum dynamics is the key to understanding the phenomena discovered in the first funding period in greater depth, controlling them in a targeted manner and being able to use them technologically,” emphasizes Matthias Vojta, Professor of Theoretical Solid State Physics at the Technical University of Dresden and Dresden spokesperson for the cluster. “We are looking forward to making physics even more beautiful in the second funding period until 2032 and to focusing more strongly on application concepts for our basic research.”
Controlling quantum processes in real time
How do quantum systems change over time, especially under time-dependent external impulses such as electric currents, magnetic fields or pressure? Questions like these are increasingly coming into focus at ctd.qmat. “Many applications in information processing, sensor technology or energy conversion are based on extremely fast switching and control processes,” explains Ralph Claessen, Professor of Experimental Physics IV at Julius-Maximilians-Universität Würzburg and Würzburg cluster spokesperson. “In the second funding period, we are developing theories on complex dynamics in topological quantum materials and investigating phenomena that only occur under dynamic control.” In order to measure and control ultrafast processes in real time, the experimental infrastructure is being further expanded. The aim is to develop quantum materials that function at room temperature and open up new possibilities for green energy technologies, energy-saving electronics, precise sensor technology or robust quantum bits.
Promising research approaches
One of the particularly promising lines of research is topological catalysis. Here, ctd.qmat scientists are investigating how topological quantum materials can be used to make electrochemical processes more economical, for example in the conversion of CO2 or the production of green hydrogen. Initial findings indicate that catalytic activity can be switched on and off through targeted time-dependent control of topological properties.
In addition, the cluster is working on new forms of topological superconductivity that could enable long-lived quantum states and more stable QuBits. Another topic is quantum sensing. For example, highly sensitive measurement methods based on individual spins are being developed.
Expanding research and infrastructure
With the new research field C “Synthetic Quantum Matter”, ctd.qmat is expanding its previous photonics focus to include artificial platforms on which quantum phenomena can be generated, amplified and precisely controlled – including those that do not occur in natural materials. There are also plans to appoint six new professorships, including experts in quantum dynamics, three at each location. A new quantum research center with state-of-the-art laboratory space will open in Dresden in 2029 together with the Leibniz Institute for Solid State and Materials Research Dresden (IFW).
What does the future sound like? Rebranding video with quantum vibe
Dresden loop artist Konrad Kuechenmeister has captured the sounds of topological materials research in Würzburg and Dresden and mixed them into a soundtrack: handmade loop music full of quantum vibes. The quantum sound can be experienced in the rebranding video of ctd.qmat, which was released to mark the premiere of the new name.
Multi-instrumentalist, producer and performer Konrad Kuechenmeister uses a looper to create rhythmic sounds and soundscapes. This effects device can be used to record music sequences and then play them back in loops.

ctd.qmat
The Cluster of Excellence ctd.qmat – Complexity, Topology and Dynamics in Quantum Matter of the Julius-Maximilians-Universität Würzburg and the Technische Universität Dresden researches and develops novel quantum materials with customized properties. Around 300 scientists from more than 30 countries are designing the foundations for the technologies of the future at the interface of physics, chemistry and materials science. In 2026, the cluster entered the second funding period of the Excellence Strategy of the German federal and state governments – with an expanded focus on the dynamics of quantum processes.
