Are you passionate about research? So are we Come and join us:

The Luxembourg Institute of Science and Technology (LIST) is a Research and Technology Organization (RTO) active in the fields of materials, environment and IT. By transforming scientific knowledge into technologies, smart data and tools, LIST empowers citizens in their choices, public authorities in their decisions and businesses in their strategies.

How will you contribute?:

You will be part of the LIST Materials Research and Technology department, where you will carry out your work in the Quantum Materials Group, led by Dr. Florian Kaiser.

Context

Quantum technologies have the potential to revolutionise the world in many aspects. Quantum colour centres in in wide bandgap semiconductors have recently emerged as a promising platform, since they can incorporate quantum systems, which can be scaled up by industrial processing.
These finding define the strategy for developing a scalable quantum technology architecture.
Our strategy is to integrate colour centres into nanophotonic silicon carbide chips at the waferscale. On the one side, this will allow us to integrate dozens to hundreds of qubit systems on one chip for quantum computing. On the other side, this will allow us to control dense ensembles of colour centres for highaccuracy quantumenhanced magnetic field sensing in the perspective of biomedical and oceanography research.

Mission

The objective of this PhD thesis is to maximise the efficiency of colour centre generation in nanophotonic waveguides. On the one side, studies on the generation of single colour centres will lead to a deterministic creation of individual spin qubits for quantum computing. On the other side, studies on generating dense ensembles of colour centres will lead to a comprehensive understanding of the ideal quantum sensor architecture, considering the interplay between signal strength and spin coherence times.
The initial part of this thesis is strongly related to colour centre generation in bulk silicon carbide crystals. You will generate colour centres based on ion implantation, which we can carry out with inhouse tools, as well as in collaboration with Surrey University (UK). Then, you will carry out a large variety of thermal annealing studies and determine their suitability in subsequent confocal microscopy experiments, which provide the crucial information on the generation yield and qubit spin coherence times. At this point, you will also be able to benefit from our ongoing activities on silicon carbide surface passivation, which intend to further improve spin coherence times.
