PhD Position in Quantum Physics: Rare-Earth Ion Single-Photon Emitters
Develop scalable quantum networks using rare-earth ion single-photon emitters in silicon-based systems.
Best for:Best for physics graduates with a strong curiosity in quantum optics, solid-state systems, and experimental AMO physics, seeking hands-on experience in nanofabrication, simulations, and cryogenics.
Overview
This PhD position at Delft University of Technology focuses on advancing quantum technologies by creating highly coherent single-photon emitters using erbium ions embedded in solid-state crystals like silicon. The project aims to build the foundational components for a scalable quantum internet, leveraging photonic crystal cavities and programmable quantum registers. The successful candidate will work in the Groeblacher Lab, contributing to experimental quantum optics, nanofabrication, cryogenics, and finite-element simulations. The role offers mentorship, training in advanced research techniques, and the opportunity to supervise master’s students while progressing toward independent research.
What you'll do
- Develop and characterize highly coherent single-photon emitters using rare-earth ions embedded in solid-state crystals.
