Project Overview
About the Position
Can silicon play a critical role in building the next generation of the internet - the quantum internet? To realise a fully functional and scalable quantum network, the Groeblacher Lab is developing highly coherent single photon emitters using erbium ions operating in the telecom C-band and directly embedded in a solid-state crystal such as silicon.
The project realises high-quality light-matter interfaces and directly enhances photon emission into an optical channel using photonic crystal cavities. By leveraging different isotopes for long-lived and programmable quantum registers, the team plans to realise all the critical parts of a quantum network using fully integrated and highly scalable structures.
Research Areas
- Rare-earth ion physics and single emitters in solid-state systems
- Photonic crystal cavities for enhanced photon emission
- Experimental AMO and quantum optics techniques
- Finite-element simulation and advanced computer-based experimentation
