Open position for master thesis project: Next-generation quantum network emitter frequency tuning
Nitrogen-Vacancies (NV) in diamond are the state-of-the-art platform for quantum internet end nodes. Our group was the first in the world to make a 3-node quantum network using NV centers in diamond . However, only 3% of the light emitted is coherent and thus can be used for entanglement generation. This limits us to scaling to larger quantum networks. Tin-Vacancies (SnV) are a promising new platform, as they emit ~60% coherent light and are in-sensitive to electronic fields in first order what makes them suitable for integration in nano-devices . In order to entangle SnVs, we need to tune their resonant frequency. This can be done by applying strain to the emitter .
This project offers the opportunity to fabricate devices that can tune SnVs centers in diamond. In addition, you have the opportunity to characterize the tunability of the SnV-centers in diamond in a state-of-the-art optical lab, contributing towards large-scale quantum networks. The focus of the project can be adjusted to your interests.
