Quantum Dynamics of Electron-Nuclei Coupled System in a Double Quantum Dot
arXiv:cond-mat/0609217 · doi:10.1063/1.2730284
Abstract
Hyperfine interaction of electron spins with nuclear spins, in coupled double quantum dots is studied. Results of successive electron spin measurements exhibit bunching due to correlations induced via the nuclear spins. Further nuclear spins can be purified via conditional electron spin measurements which lead to electron spin revivals in the conditional probabilities. The electron spin coherence time can be extended via conditional measurements. The results are extended to a single electron on a single QD.
