Establishing a successful long-lived quantum memory is an essential stepping stone to many quantum communications applications. Quantum dots have been an increasingly attractive platform for this implementation since the recent demonstration of a deterministic and coherent control interface between a single electron confined in a quantum dot and a nuclear bath. However, to-date high-fidelity state transfer using this interface remains an elusive goal as the competition between various nuclear modes places a constraint on what operations can be performed. My masters project proposes to address this is by polarising the nuclear ensemble, thus introducing selectivity between the nuclear modes. In this talk, I will review the physics behind this coherent electron-nuclear interface, the experimental techniques used to implement it, and the preliminary results I have obtained.
