Possible transfer processes composed of two successive tunneling processes for an incoming spin s = ↑ (first: solid arrow, second: dashed arrow); the initial states of the dots are indicated; a) and b) are coherent processes, c) corresponds to an incoherent spin-flip process.

Scanning electron microscope image of a two quantum dot system with separate leads in a lateral arrangement. With a top gate covering both quantum dot sites, the electrostatic interaction is enhanced.
