The SFB Correlated Quantum Materials and Solid State Quantum Systems – SFB Q-M&S – is a collaborative research project funded by the Austrian Science Fund (FWF) and the German Research Foundation (DFG), with 10 PIs hosted at 4 institutions in Austria and Germany. We aim to bridge the fields of correlated quantum materials and solid state quantum systems, to advance both.
The Special Research Area (SFB states for “Spezialforschungsbereich” in German) is one of the funding programs of the FWF aiming at establishing research networks based on international standards through autonomous research concentration at a single university location and building up extremely productive, tightly interconnected research units for long-term and inter- or multidisciplinary work on complex research topics.
Hopes are high that quantum computers will revolutionize conventional computation and data processing. Although they can already perform certain computations faster than conventional computers, more robust solid state quantum systems are needed to solve the problem of quantum error correction and fully exploit the potential of quantum computing. A currently disjunct field are correlated quantum materials. These are designer materials with properties due to quantum effects of strongly interacting electrons. They represent a highly active but particularly complex area of fundamental solid state physics.
The SFB Q-M&S aims to connect both areas. Concepts and methods developed in the context of quantum information and computation will contribute to a better understanding of correlated quantum materials. For example, “entanglement meters” will be devised to unravel the mystery of the strange metal state that underlies high-temperature superconductivity. In turn, research will be conducted into how correlated quantum materials can be used for quantum applications. Correlated quantum materials with topological properties for instance could lead to very robust and well-controllable quantum devices in novel hybrid systems.
