(color online) (a) Scanning electron micrograph of the SiGe double quantum dots. (b) Stability diagram of the DQD and schematic of different steps during operations (marked by black points). (c) Rabi oscillations between spin-up and spin-down state of the electron in the right dot. (d) as a function of τ_R and probe frequency f_p. There are two resonances of the left qubit and their frequencies are split by J. The response of the left spin qubit oscillates between these two frequencies as the right qubit oscillates between spin-up and spin-down. The figure comes from Ref. [17].
