Ornago, L. (author)In this dissertation, we analyse the charge transport of nanoscale molecular junctions in mechanically controllable break junction (MCBJ) experiments. In particular, we focus on the characterization of molecular features going beyond the "single-peak" picture, that is, considering features in the measurements in addition to themost prominent one...doctoral thesis 2023

Möhle, C.M. (author)Majorana zero modes (MZMs) are a topic of intense research as they constitute the main building block of topological qubits - a qubit type with potentially enhanced coherence time. A promising way to create these quantum states is to couple a one-dimensional (1D) semiconducting segment with spin-orbit interaction to a superconductor, in the...doctoral thesis 2023

van der Zalm, Joost (author)One of the main components used in superconducting quantum chips is the Josephson junction. Currently when fabricating Josephson junctions, the resistance uniformity at wafer-scale is not optimal. It is also known that an annealing process can alter the junction resistance and with it the qubit frequency. However, laser annealing has only shown...master thesis 2022

Brookman, Jasper (author)Conventional semiconductor diodes dissipate energy in the form of heat when current passes through them. This is unwanted in, for example, cryogenic environments. Using a superconducting diode could mitigate this problem. These have been made by using special materials or combining multiple different circuit elements. We provide a systematic...bachelor thesis 2022

Storani, Facundo (author), Di Pace, Roberta (author), De Schutter, B.H.K. (author)The paper proposes a traffic responsive control framework based on a Model Predictive Control (MPC) approach. The framework focuses on a centralized method, which can simultaneously compute the network decision variables (i.e., the green timings at each junction and the offset of the traffic light plans of the network). Furthermore, the...journal article 2022
