Project title (internship): Design of superconducting microstrip resonators for space applications.
Description: The aim of this project was to design and fabricate superconducting microstrip resonators for space applications.
Host: CosmoNanoscience Group, Kavli Institute of Nanoscience, TU Delft.
Supervisor: Prof. Dr. J. Baselmans
Project title (Master thesis, project 3): Determination of phthalocyanines and porphyrins Seebeck coefficients using UHV STM break junctions technique.
Description: The aim of this project was to measure the thermopower of phthalocyanines and porphyrins. We performed thermopower measurements on gold break junctions using scanning tunnelling microscope (STM). The measured thermopower was found to be one order of magnitude smaller than the expected thermopower for the molecules. In the course of this project we improved measurement apparatus to enhanced signal to noise ratio. We enhanced the stability of the STM and allowed a better control over the pressure.

Project title (Master thesis, project 2): Jaynes-Tavis-Cummings pseudo spin coupling through dissipation.
Description: Identical qubits strongly coupled to the cavity can be modeled with Tavis-Cumming Hamiltonian. The Hamiltonian for such system can be reduced to a block diagonal form with subsystems. If we initialize system in one of these subsystems, it can never leave this subsystem. The noise can however lead to mixing between the subsystems. We solved Lindblad master equation considering dephasing and relaxation, for two identical qubits coupled to the cavity. The solution shows that singlet and triplet states mix in the presence of dephasing, although relaxation does not mix them. Next step is to obtain the solution for the Lindblad master equation for more qubits.

Project title (Master thesis, project 1): Geometric optimisation of transmon-qubit coherence times.
Description: In this project we compared the performance of transmon-qubits with different geometrical parameters to investigate the influence of noise on this type of systems. We vary not only lateral dimensions of the qubits, but we put holes on the ground plane and made aluminum layer thinner. We observed improvement in the relaxation and coherence times by a factor of 2. Measurement of another sample, where we vary only the lateral size of the qubits, showed that relaxation time increases with the lateral size of the transmon-qubit.

Project title (Bachelor thesis):Experimental investigation of operating conditions of Hall thrusters with different jet luminosity
Description: In this project we compared two operating modes of two different Hall thrusters. During the life tests of Hall thruster KM-60 it has been found that this thruster can operate in two different modes. Switching between these two modes occurs abruptly and the cause of this switching is still unknown. We investigated the switching experimentally and obtained an empirical description of two regimes. We found that the magnetic fields in the inner and outer coils of the thruster are the critical parameters in this description.
