TL;DR: The observation of a quantized conductance plateau at 2e2/h in the zero-bias conductance measured in indium antimonide semiconductor nanowires covered with an aluminium superconducting shell strongly supports the existence of Majorana zero-modes in the system.

TL;DR: A technique for generic bottom-up synthesis of complex quantum devices with a special focus on nanowire networks with a predefined number of superconducting islands is demonstrated, opening up new avenues for the realization of epitaxial three-dimensional quantum architectures which have the potential to become key components of various quantum devices.

TL;DR: In this paper, the emergence and characterization of Majorana bound states in realistic devices based on hybrid semiconducting nanowires and their connection to more conventional Andreev bound states are discussed.

TL;DR: In this article, a series of electron transport experiments on semiconductor nanowires were conducted towards realizing the hypothesized topological quantum computation. But the experiments in the dissertation aim for eliminating the disorder on the surface of the nanowire, and in the interface between the Nanowire and the superconductor.

TL;DR: The structural and chemical analyses demonstrate a high-quality interface between the nanowire and a NbTiN superconductor that enables ballistic transport and pave the way for disorder-free Majorana devices.
