Nuclear Spins as Quantum Memory in Semiconductor Nanostructures
We theoretically consider the possibility of using solid state nuclear spins in a semiconductor nanostructure environment as long-lived quantum memory. In particular, we calculate, in the limit of a strong applied magnetic field, the quantum coherence time for P donor nuclear spins in random bath environments of Si and GaAs, and the lifetime of excited intrinsic spins in polarized Si and GaAs e...
متن کاملManipulation of nuclear spins in semiconductor nanostructures
A single electron spin localized in III-V semiconductor structure is an attractive candidate for a solid state quantum bit. An outstanding bottleneck towards spin-based quantum computation has been the fast dephasing of the electron spin by the inevitable nuclear spin environment. In this talk, I will discuss preparations of nuclear spin environment using optical and electrical controlled dynam...
متن کاملNuclear spins in nanostructures
We review recent theoretical and experimental advances toward understanding the effects of nuclear spins in confined nanostructures. These systems, which include quantum dots, defect centers, and molecular magnets, are particularly interesting for their importance in quantum information processing devices, which aim to coherently manipulate single electron spins with high precision. On one hand...
متن کاملElectron and nuclear spins in semiconductor quantum dots
The electron and nuclear spin degrees of freedom in two-dimensional semiconductor quantum dots are studied as important resources for such fields as spintronics and quantum information. The coupling of electron spins to their orbital motion, via the spinorbit interaction, and to nuclear spins, via the hyperfine interaction, are important for understanding spin-dynamics in quantum dot systems. T...
