Mission

Fundamental research in quantum nanoscience is of utmost importance for the emerging quantum technologies, including quantum computing. We use our extensive knowledge in surface science and nanoscience to contribute to quantum nanoscience and its primary goal: the manipulation and exploitation of quantum-coherent functionality in nanostructures.

Head: Prof. Dr. F. Stefan Tautz

Free coherent evolution of a coupled atomic spin system initialized by electron scattering

Insight into the dynamics of a coupled atomic quantum system

Recently published in Science and discussed on phys.org, we observed the coherent flip-flop evolution between two atomic spin qubits. (Artwork by Enrique Sahagún, Scixel)

Topological interfaces, nanostructures and devices for quantum computing

Topological interfaces, nanostructures and devices for quantum computing

We use the “multimeter at the nanoscale”, our proprietary multi-tip scanning probe microscope, for measurements of quantum transport in nanoscale structures and devices. (A. Leis et al. Scientific Reports 2020, 10, 2816)

Spin qubits at surfaces of condensed matter

Spin qubits at surfaces of condensed matter

We address the challenge of performing coherent experiments on single spins in atoms and molecules on surfaces – with the aim of eventually establishing them as qubits. (T. Esat et al., Nature 2018, 558, 573)

Nanofabrication with single molecules

Nanofabrication with single molecules

Our long-term goal is the design and implementation of a technology for the rapid prototyping of nanoscale functional quantum systems - "3D printing" with single molecules, executed with the tip of a scanning probe microscope. (P. Leinen et al., Science Advances 2020, 6, eabb6987)

Advanced imaging methods for quantum nanoscience

Advanced imaging methods for quantum nanoscience

We have an outstanding track-record in the development of novel scanning-probe imaging methods, which is complemented by our pioneering work on photoelectron tomography, a reciprocal-space imaging technique of molecular wave functions. (R. Wallauer et al., Science, eabf3286)
