(a) Scanning electron micrograph of the device and the schematic of the measurement setup. A DQD is formed at the lower side, and the charge states are monitored by the charge sensor QD at the upper side. The charge sensor is connected to resonators formed by the inductor L and the stray capacitance C p for RF reflectometry. The external magnetic field of 0.5 T is applied in plane along the z axis. (b) ΔV sensor as a function of V P2 andV P1. Charge states are identified by distinct levels in ΔV sensor . The number of electrons in each QD is given as (n 1, n 2). The triangle shows the region of the spin blockade. The positions corresponding to steps of pulse sequences (O i , I, M) are indicated. (c) Schematic of the measurement scheme. The spin state is initialized to a (0, 2) singlet at I. Next, we move into O i in (1, 1) where the spin couples to the lead. Finally, the spin state is measured using spin blockade at M.
