Spin qubits in silicon quantum dots offer a promising pathway for quantum computing due to their relatively long coherence times. However, operational efficiency is challenged by decoherence mechanisms, such as nuclear spin hyperfine interactions and spin-orbit coupling effects. This project employs advanced simulation tools to analyse the noise contributions affecting qubit performance. The objective is to develop and optimize control sequences to mitigate these noise sources, enhancing the qubits' overall performance and stability for quantum computing applications.
