Opportunities for Bachelor/Master/PhD Students and Postdocs

Research in the department focuses on solid-state quantum systems for quantum optics and quantum communication, and molecular quantum systems. The core competence is the fabrication, characterisation and embedding of quantum emitters in photonic structures (e.g. microcavities). A variety of clean room fabrication methods, such as molecular beam epitaxy and/or electron beam lithography, can be used to create nanostructures for nanophotonic applications.

In a bottom-up approach using molecular beam epitaxy, we develop novel and advanced quantum architectures on different substrates (Si, GaAs, and InP) and investigate their quantum optics properties. With the top-down approach, we fabricate photonic nanostructures and semiconductor devices through high-resolution electron beam lithography and etching techniques. The fabricated nanostructures emit at different wavelengths — particularly in the telecom C-band. An innovative hybrid photonics platform can be created by integrating III-V semiconductor light sources into silicon, which is one of the key technologies combining the best of both materials. Additionally, we develop charged devices for spin manipulation. In our research on molecular systems, we aim to develop an alternative platform that may overcome the current constraints related to miniaturization and scalability.

Photonic Quantum Technologies: Science and Applications, John Wiley & Sons (2023).

The aim here is to bring together scientists with different expertise from across different disciplines. Fundamentals and applications of photonic quantum technologies are covered. This book provides readers with cutting-edge knowledge they need to understand and develop practical quantum systems in one place. It also gives a comprehensive overview of quantum technologies, including discussions of the second quantum revolution (by Nobel Laureate Alain Aspect). It explores the practical application of quantum technology as well as emerging technologies. The development of quantum technologies involving artificial atoms, color centers, molecules, atoms, and ions is discussed.
