AbstractRecent experiments with an electrostatically gated structure demonstrated coherent oscillations, involving all three spins of a linear triple dot system. In a combined experimental and theoretical study, we demonstrate coherent doublet/doublet exchange oscillations, leading to arbitrary rotation on the relevant Bloch sphere, and we reveal an interplay between exchange and hyperfine-driven "double coherent beam splitter" oscillations.
