In this paper an introduction to this subject will be given. Some theoretical approaches to the problem will be outlined. Most attention will be given to the Quasi-Static Bath Approximation, to the cluster expansion theories of dephasing due to the nuclear dynamics induced by the dipolar interactions (spectral diffusion), and to the effective Hamiltonian based theory of dephasing due to hyperfine-mediated interactions. The connections between the theoretical results and various experiments will be emphasized.", "revisions": [ { "version": "v3", "updated": "2011-04-14T16:55:59.000Z" } ], "analyses": { "keywords": [ "electron spin qubits", "iii-v quantum dots", "cluster expansion theories", "quasi-static bath approximation", "dipolar interactions" ], "tags": [ "conference paper", "review article", "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1009.4466C" } } }
