A theoretical model shows near-perfect electron transfer from a static quantum dot into a surface-acoustic-wave moving dot is possible, with first-order protection against Rashba-Dresselhaus spin-orbit errors at the optimal operating point.
However, in GaAs the presence of structural inversion asymmetry and bulk inversion asymmetry give rise to both Rashba [ 40] and Dresselhaus [ 41] spin orbit coupling

Electron transfer between surface-acoustic-wave-induced moving and static quantum dots
A theoretical model shows near-perfect electron transfer from a static quantum dot into a surface-acoustic-wave moving dot is possible, with first-order protection against Rashba-Dresselhaus spin-orbit errors at the optimal operating point.
