Ramsay, A.J., Boyle, S.J., Kolodka, R.S. et al. (6 more authors) (2008) Fast optical preparation, control, and readout of a single quantum dot spin. Physical Review Letters , 100. 197401. ISSN 0031-9007
Abstract
We propose and demonstrate the sequential initialization, optical control, and readout of a single spin trapped in a semiconductor quantum dot. Hole spin preparation is achieved through ionization of a resonantly excited electron-hole pair. Optical control is observed as a coherent Rabi rotation between the hole and charged-exciton states, which is conditional on the initial hole spin state. The spin-selective creation of the charged exciton provides a photocurrent readout of the hole spin state.
