Abstract
Quantum computers based on semiconductor quantum dots are proving promising contenders for large scale quantum information processing. In particular, group IV based semiconductor hosts containing an abundance of nuclear spin-zero isotopes have made considerable headway into fulfilling the requirements of a universal quantum computer. Silicon (Si) and germanium (Ge) are two elements that have played important roles in the history of classical computing, and are now poised to do the same in the future of quantum computation. In this thesis, we advance efforts in developing a quantum computer in both Si, using electron spins in Si-metaloxide- semiconductor (SiMOS) hosted quantum dots, and hole spins in planar germanium quantumwells (Ge/SiGe).
