Research Interests
My research interests are in the development of quantum technologies, with a focus on encoding quantum information in single photons. I am interested in developing novel waveguide structures for quantum information applications, such as on-chip single photon sources, quantum gates and efficient fibre coupling. Likewise, I am interested in using photonics to demonstrate innovative quantum algorithms and protocols for quantum technology, for example experimentally validating quantum enhancement over classical protocols. Lastly, machine learning has revolutionised computing and I am interested in applying machine learning to quantum technology to overcome challenges that are impractical to solve by analytic or brute-force methodologies.
In the Photonics Group at the University of Innsbruck, I focus on the development of a hybrid waveguide platform to quantum communication that will enable totally secure information transmission with minimal hardware cost. Ultimately, this will combine on a single device, lasers, single photon sources, passive and active optical elements, and efficient fibre coupling. This project is within the EU Quantum Technologies Flagship project UNIQORN.
