Quantum-dot spin qubit and hyperfine interaction
D. Klauser, W. A. Coish, Daniel Loss
Abstract
We review our investigation of the spin dynamics for two electrons confined to a double quantum dot under the influence of the hyperfine interaction between the electron spins and the surrounding nuclei. Further we propose a scheme to narrow the distribution of difference in polarization between the two dots in order to suppress hyperfine induced decoherence.
