B.Sc. Project Thermal Solutions for Large Scale Quantum Computing

In this project, you will perform thermal simulations of our experiments in order to gain insights on the performance and constraints for large scale quantum computing. You will devise an experiment to gather the necessary low temperature data needed for a cryo-toolkit for spin qubits. This knowledge is essential for future quantum processors.

M.Sc. Project Cryogenic DACs for Spin Qubit Control

In this project, you will measure the performance of a custom developed cryogenic digital-to-analog converter (DAC) by connecting its outputs to the DC gate electrodes of a spin qubit. Crogenic control electronics like this DAC present a promising route for scaling qubits from lab to industrial applications.

B.Sc. Project Further development of an experiment to illustrate the wave-particle duality

In this project you will work on the further development of a setup to illustrate the wave-particle duality. Different components will be tested in the setup and experimental data will be evaluated. Furthermore, new evaluation software for the setup shall be written, which can be used in as many computer systems as possible. The objective is to use the setup in an experimental module of the physics labs for school students.

B.Sc. Project Development of the Hanbury-Brown-Twiss and Hong-Ou-Mandel experiments to be used with high school students

In this project you will work with experiments on the Hanbury-Brown-Twiss effect as well as the Hong-Ou-Mandel effect. Both experiments are to be used in an experimental module of the physics lab for high school students. The experiments will be used in physics practical courses, so the instructions provided currently are aimed at physics students. The objective is to adapt the content of the experiments, particularly at the mathematical level, so that the difficulty of the tasks is adequate for high school students.

B.Sc. Project Dark-field microscopy for resonant excitation of self-assembled quantum dots

In this project, you will develop dark-field optical microscopy setup based on polarization optics. You will use it to characterise properties of the InAs quantum dots under resonant excitation. To achieve this goal you will add the polarization optics in the existing micro-photoluminescence setup and develop an algorithm to align it for a maximum signal to background ratio.

M.Sc. Project: Time Multiplexed Optical Qubit Readout

In this project, you will be designing optical cavities to facilitate the collection of photons emitted by quantum dots into optical fibers. This project is part of a new activity initiated by the Chair of Integrated Photonics (IPH) together with the Quantum Technology Group on time-interleaved (multiplexed) optical readout of quantum dots.

M.Sc. Project: Development of electron spin qubits in ZnSe using a shadow-mask technology

ZnSe exhibits ideal properties for hosting electron spin quantum bits. However, this II/VI semiconductor has not been considered for this purpose. Under supervision of Alex Pawlis (FZ Jülich), who is an expert in the growth of (Zn,Mg)Se heterostructures, you will electrically characterize (Zn,Mg)Se heterostructures and fabricate quantum dot devices.
