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