We show that the number of electrons confined in a semiconductor quantum dot has a strong influence over the Rashba and Dresselhaus spin-orbit (SO) admixture. This can be exploited to improve the lifetime of spin excitations, as compared to the usual oneand two-electron devices. The physical mechani
