Research Interests

The field of quantum information processing always fascinated me. Harnessing the fundamental properties of quantum mechanics for computation is my preferential research intereset. In this context, I worked on the realisation of strong coupling between a superconducting microwave resonator and an ensemble of phosphorus donors in silicon.

At UCL, I continue my work on quantum hybrid systems, combining donors in silicon with superconducting resonators or silicon quantum dots. Such hybrid systems comprise the advantages of both sub-systems, granting long storage times and fast processing.

Interesting fact

Before I started my physics studies, I did a vocational education as electrician.
