Universal Scaling of Hyperfine-Induced Electron Spin Echo Decay
Neil Shenvi, Rogerio de Sousa, K. Birgitta Whaley
The decoherence of a localized electron spin in a lattice of nuclear spins is an important problem for potential solid-state implementations of a quantum computer. We demonstrate t…
Non-Perturbative Bounds on Hyperfine-Induced Electron Spin Coherence Times
Neil Shenvi, Rogerio de Sousa, K. Birgitta Whaley
We address the decoherence of a localized electron spin in an external magnetic field due to the hyperfine interaction with a lattice of nuclear spins. Using a completely non-pertu…
Qubit coherence control in a nuclear spin bath
Rogerio de Sousa, Neil Shenvi, K. Birgitta Whaley
Coherent dynamics of localized spins in semiconductors is limited by spectral diffusion arising from dipolar fluctuation of lattice nuclear spins. Here we extend the semiclassical…
