I am a PhD candidate working on donor spin qubits in Silicon as part of prof. Andrea Morello's lab. Being from the Netherlands I moved to Sydney in 2023. Before this I did my master in applied physics at Delft University of Technology in the Netherlands. Here I researched the quantum Hall effect in superconductor-semiconductor hybrid systems.

So far, I have worked on the coupling of Phosphorus donors via the exchange interaction. Coupling the donor atom to other donors or quantum dots will be a key aspect of the platform and the exchange interaction will likely play a key part. Right now, I switched focus on the Antimony donor as a platform for quantum information. In the future, I hope to combine the two subjects by exchange coupling two antimony donors.
