The spin of an individual electron in a quantum dot has been proposed as an attractive candidate for quantum information processing due to it's potentially long coherence time. Specifically, Si/SiGe quantum dots promise a particularly long spin coherence time due to reduced electron-nuclear spin interaction. However, the weakly-interacting nature of the electronic spin, while protecting it from decoherence, also makes spin manipulation and read-out difficult. Previous successful operation of a radio-frequency single-electron transistor (RF-SET) coupled to a Si/SiGe double quantum dot (DQD) by our group has demonstrated a charge sensitivity of 4 × 10-6 e/Hz1/2.
