Extensible 2xN Quantum Dot Arrays: Encoding Arrays of Spin Qubits Implemented Using Holes in a Germanium Heterostructure

This thesis work attempts to work through the design, simulation, fabrication and measurement of a new, more complex, extendable qubit array design. By confining the array to a pseudo-1-dimensional space, we allow for full, individual gate control, while adhering to the strict fabricational requirements of such a device. As we are working with limited material, an implementation of an open-source simulation of the Poisson equation is also achieved, to ensure that the designs will function as intended. The fabricational and measurement results demonstrate the ability to fabricate these complex devices, and have key components be functional.
