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 article, the electronic transport across a junction between two merged InSb nanowires is studied to investigate how disordered these nanowire networks are, and conductance quantization plateaus are observed in most of the contact pairs of the epitaxial In Sb networks: the hallmark of ballistic transport behavior.
