Biography

I am a researcher working on experimental quantum physics with trapped ions at the University of Innsbruck.

We are investigating a physical platform that might host a future quantum computer - Trapped atomic ions. The quantum register consists of a string of individual atoms that store information in their internal state. We confine ionized Calcium atoms and manipulate their state with laser pulses. Below is an image of a 55 ion quantum register from our EU flagship project AQTION.

I have received an ERC starting grant to apply these quantum computing techniques to polyatomic molecules within the QCosmo project. In particular, I plan to characterize and control ultrafast quantum processes single polyatomic molecules by coupling them to trapped atomic ions. Ultimately, we hope to exploit these quantum effects in molecules as a versatile foundation for future quantum technologies.

I am currently looking for motivated PhD students and PostDocs that will join me on this scientific journey. If you are interested in coming to Innsbruck, contact me.

Research interests

We are developing a trapped ion quantum computer, where each qubit is stored in a single atom. In our experiments, we trap single atomic ions in Paul traps and manipulate their internal states with laser light. My current research interests can be divided into:

Quantum algorithms

segmented trap

We are investigating quantum operations that will fuel future quantum computers based on trapped atomic ions. We create exotic entangled quantum states and perform small-scale quantum algorithms in quantum registers with more than 10 qubits… More

Scalable quantum architectures

We use the knowledge of implementing algorithms as the basis for developing quantum computing architectures that will be capable of controlling more than a hundred qubits. In collaboration with Infineon technologies, we are fabricating and testing the building blocks of such an architecture in an industrial setting… More

Quantum control of single molecules

moleule

Molecules show a much richer internal structure than atoms and offer thus complex quantum dynamics that are not fully understood. Within the QCosmo project, we will use the control techniques that we have developed for single atomic ions to characterize and control ultrafast dynamics in single molecular ionsMore
