Currently 13 independent research groups work in the area of quantum sciences at our Department. There are strong synergies between four theory groups and eight experimental groups. The main areas of research are quantum computing, quantum measurements, spintronics and quantum magnonics, quantum sensing, quantum optics and cold atoms, topological properties of condensed matter systems, and quantum communication.
For example, in our department, we employ single spins in NV sensors or nano-mechanical systems to develop practical sensing applications. We study the quantum properties of light and its interaction with atomic and mechanical systems and explore the quantum physics of atoms, photons, phonons, and magnons. We work with nano-devices to explore fundamental electrical properties in low-dimensional systems such as carbon nanotubes, semiconducting nanowires, quantum dots, and graphene.
We combine different contact materials, for example ferromagnets, superconductors, and normal metals, to arrive at unconventional hybrid systems. We study questions related to quantum computing, such as the various mechanisms of relaxation and decoherence, physical and logical implementation of elementary quantum gates. We also work on novel topological quantum bits that are of interest for quantum computation such as Majorana fermions and parafermions. We work on theoretical quantum information science such as surface codes, quantum error corrections, and quantum memories.
