A global effort is pursued to realise a quantum computer. Such a dispositive will allow to implement faster algorithms for tasks like integer factoring and database search. It will also allow to simulate quantum system much more efficiently. than a classical system. This power gain necessitates to entangle a large number of qubits. This in turn requires the ability to transport a qubit in space. In this thesis, we demonstrate a first step: a single electron is transported on demand from one quantum dot to another quantum dot, micrometers away. The transport is realised thanks to a Surface Acoustic Wave (SAW) that drags the electron. The transfer is realised with an efficiency of 90 % and triggered within one nanosecond. These results open t...
