Decoherence in nanostructures and quantum systems

Abstract: Decoherence phenomena are pervasive in the arena of nanostructures but perhaps even more so in the study of the fundamentals of quantum mechanics and quantum computation. Since there has been little overlap between the studies in both arenas, this is an attempt to bridge the gap. Topics stressed include (a) wave packet spreading in a dissipative environment, a key element in all arenas, (b) the definition of a quantitative measure of decoherence, (c) the near zero and zero temperature limit, and (d) the key ro… Show more

“…This brings the thermal time scale to β ∼ 10 −9 sec, which is close to the single-qubit control times 10 −11 -10 −7 sec [16][17][18][19][20][21][22][23]. Alternatives to the Markovian approximation have been suggested [24][25][26][27][28][29].…”
