Dephasing of electron spin qubits due to their interaction with nuclei in quantum dots
Ł Cywiński - arXiv preprint arXiv:1009.4466, 2010 - arxiv.org
Coherence of spins of electrons confined in III-V quantum dots is strongly affected by their
hyperfine interaction with the nuclei. In this paper an introduction to this subject will be given …

Collective nuclear stabilization by optically excited hole in quantum dot
W Yang, LJ Sham - arXiv preprint arXiv:1012.0060, 2010 - arxiv.org
We propose that an optically excited heavy hole in a quantum dot can drive the surrounding
nuclear spins into a quiescent collective state, leading to significantly prolonged coherence …
