Researcher (PhD Position) in Quantum Networks
(salary scale 13 TV-L, 75 %)
Nestled in a modern city surrounded by nature and with an exceptional standard of living, Leibniz University Hannover offers excellent working conditions in a vibrant scientific community.
The Institute for Solid State Physics, Group of Prof. Fei Ding and Michael Zopf, welcomes applications for the following position starting as soon as possible: Researcher (PhD Position) in Quantum Networks (salary scale 13 TV-L, 75 %)
The fixed-term position is limited to 3 years.
We are seeking a motivated PhD candidate to join our internationally renowned research group, contributing to the development of distributed quantum networks based on semiconductor quantum light sources. This role offers the opportunity to advance long-distance quantum communication using quantum dots (QDs), solid-state single-photon sources, and nanophotonic devices.
The vision for our group
We are advancing semiconductor quantum photonics to develop scalable quantum networks that operate on-chip and across fiber infrastructures. Our research focuses on quantum light sources, entanglement distribution, and standardized quantum technologies, bridging fundamental science with real-world applications. By driving innovation in secure quantum communication, precision metrology, and next-generation photonic devices, we aim to bring quantum photonics to life and shape the future of quantum technology.
Our group focuses on research in semiconductor-based single and entangled photon generation and their application in quantum networks. By harnessing quantum dots—often called artificial atoms—we aim to establish scalable quantum networks, enabling secure quantum communication and enhanced metrology applications. This project is part of a larger initiative to build Niedersachsen Quantum Links, a metrology-assisted fiber testbed connecting key research institutions, including Leibniz University Hannover, PTB, and TU Braunschweig. The PhD student will contribute to the integration of semiconductor quantum light sources in networked quantum systems and develop novel photonic architectures for quantum information transfer.
Your responsibilities
1. Optimize the implementation of quantum dot-based sources in distributed quantum networks
2. Test quantum photonic devices for single and entangled photon distribution over distributed fiber links
3. Collaborate with leading experts in quantum communication, photonics, and metrology
4. Conduct experimental research in quantum optics, single-photon detection, and system integration
5. Participation in international collaborations and writing of scientific publications
Your profile
6. Completed university science degree (Master) in physics, electrical engineering, or a related discipline
7. Strong background in quantum optics, photonic devices, and / or semiconductor physics.
8. Experience with quantum light sources, fiber-based quantum communication, or nano-photonics is a plus
9. Programming skills for data acquisition and experimental control (e.g. Python)
10. Excellent analytical, problem-solving, and communication skills
11. Good written and spoken English skills
Equal opportunities and diversity are core values at Leibniz University Hannover. Our goal is to tap into individual potential and open up possibilities. We therefore welcome applications from anyone interested in the position, irrespective of gender, nationality, ethnic origin, religion or ideology, disability, age, sexual orientation and identity.
We strive towards a balanced and diverse workforce and a reduction in under-representation in accordance with the Lower Saxony Equal Rights Act (Niedersächsisches Gleichberechtigungsgesetz – NGG). We therefore also welcome applications from women for the above-mentioned position. Preference will be given to equally-qualified candidates with disabilities.
Why join us?
12. Be part of groundbreaking quantum research with real-world applications in communication and metrology
13. Access state-of-the-art quantum laboratories and collaborations across leading institutions
14. Work in an international and interdisciplinary team
15. Competitive TV-L salary and opportunities for career growth
