| Abstract | In this paper we describe our recent experiments on coherent manipulation of electron spin states formed in a highly tunable GaAs/AlGaAs triple quantum dot device. The coherent evolution of spin states is achieved by using fast pulses from an initialization point in the (201) charge configuration region of the stability diagram. We demonstrate the versatility of the triple dot system capable of tuning to different regimes controlled by the width of the (111) region and pulse parameters. In particular we observe Δ'1/2-Q3/2 (analogue of S-T+ in a double dot) and Δ'1/2-Δ1/2 exchange driven oscillations from both sides of the stability diagram involving all three spins. © 2013 WILEY-VCH Verlag GmbH & Co.
