Open positions

In September 2021 I am joining the Institute of Quantum Technologies of the German Aerospace Center (DLR) in Ulm, Germany, and I am inviting motivated scientists to join our group to work on Quantum information theory based on solid state spin qubits.
We have two PhD positions and one postdoc position.

Squeezed hole spin qubits in Ge quantum dots with ultrafast gates at low power

We propose a minimal design modification of Ge planar quantum dot devices that enhances the spin-orbit interaction by orders of magnitude and enables low power ultrafast hole-spin qubit operations.
