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

The stabilization potential of a standing molecule

The stabilization potential of a standing molecule

Fabricated single-molecule devices can be very fragile. In Science Advances we reported measurements and calculations of the stability of standing PTCDA. In an interview, Dr. Christian Wagner describes the challenges of this work.

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)
