Abstract

Quantum computing based on spintronic nanodevices has been of intense study most motivated by the discovering of both search and factorization quantum algorithms. Spin lifetime, decoherence and entanglement occurring in these devices are crucial in determining the quantum information process. In this sense, we study here the spin-orbit interaction (SOI) effects on the electronic ralaxation mechanisms occurring in both two- and one-dimensional semiconductor devices. Also on this subject, we will explore the role of nuclear spin in zero-dimensional nanostructures. (AU)
