Abstract
The knowledge of electron and hole g-factors, in particular their control and engineering, is the key to the use of the spin degree of freedom for information processing in solid-state systems. The electronic g-factor will be material-dependent, the effect being larger for materials with large spin–orbit coupling. Since electrons can be individually trapped in quantum dots in a controllable manner, they may represent a good platform for the implementation of quantum information processing devices. Here we use self-assembled quantum dots of InAs embedded in GaAs for the g-factor control and engineering.
