Research groups around the world are looking to develop a qubit protected from decoherence for achieving quantum advantage in computations. This would have huge impact on the modern world. The applications are many from drug development to cryptography and many more elds. Indium-Arsenide Nanowires with an epitaxially matched thin lm of lead grown with Select-Area-Growth could prove to be a platform for building scalable qubits. The work in this thesis is to create a device capable of measuring the superconductivity of the samples InAs-Pb grown at the Center for Quantum Devices, Niels Bohr Institute. The InAs semiconducting nanowires serves as one dimensional system that could host Majorana Zero Modes if coupled to a superconductor such as Pb. The MZMs emerges at the edges of the nanowires. The device created is a 4-probe device that should be used to measure the induced topological superconductivity inside the device. The project was able to such a device using electron beam lithography techniques and development of the fabrication process of InAs-Pb SAG NW Devices was furthered.
