"Investigating the rules of quantum mechanics at the single particle level
to enter new regimes in quantum science and to achieve superior quantum control
is the driving force behind my research. "

Expertise and Experimental platforms

Quantum Simulations are key for the investigation of quantum mechanical properties. By using a well controlled quantum mechanical system one can implement and study tailored Hamiltonians and unlock new types of matter.

During my PhD thesis work in the group of Prof. Francesca Ferlaino I used the toolbox of lattice-confined dipolar atoms to perform Quantum Simulations of exotic inter-atom interactions that extend across neighboring lattice sites.

The realization of quantum networks requires versatile quantum network nodes to distribute entanglement across the network and to store it for further processing.

As an Erwin-Schrödinger fellow at QuTech, TU Delft, I, together with the team led by Prof. Ronald Hanson, have build the first quantum network exceeding two quantum network nodes – a crucial step to realize a future Quantum Internet.

Cavity coupled trapped ions are a promising platform to realize long-range quantum networks due to their superior spin-photon coupling efficiencies and entanglement fidelities, and a communication wavelength compatible for high efficient conversion to telecom frequencies.

In 2020 I have joined the group of Prof. Tracy Northup within my Erwin-Schrödinger fellowship to bring the vision of a long-distance Quantum Network further ahead.
