Arjen Vaartjes is a PhD student working on global control and quantum sensing in Antimony qudits in Silicon. Currently he is exploring the creation of non-classical states in a high-dimensional nuclear spin embedded in a silicon nano-electronic device. Additionally, he worked on microwave vacuum squeezing in superconducting amplifiers in collaboration with Dr. Jarryd Pla. Previously, he has completed his master's degree at the Technical University of Delft on Bound states in superconducting devices.
