The demand for ever-increasing computational power cannot be met anymore by the advancement of microelectronics. Quantum computing present itself as the solution to this problem, with multiple qubit platform being currently under development. The flying electron qubit architecture appears to be a promising candidate due to its potential for scalability. However, the technology is still in its infancy and several building blocks are still missing, among which a reliable single electron source. In this work, the leviton single electron source will be extensively studied. Two different techniques for the generation of ultrashort electron wave packets will be presented. Finally, asingle electron wave packet will be characterised while propagating in a 2DEG..
