The canonical example of a quantum-mechanical two-level system is spin. The simplest
picture of spin is a magnetic moment pointing up or down. The full quantum properties of …

We review the recent progress in theory and experiments with lateral triple quantum dots
with controlled electron numbers down to one electron in each dot. The theory covers …

Recent experiments have demonstrated quantum manipulation of two-electron spin states in
double quantum dots using electrically controlled exchange interactions. Here we present a …

We present a quantum solution to the electron spin decoherence by a nuclear pair-
correlation method for the electron-nuclear spin dynamics under a strong magnetic field and …

We consider the decoherence of a single localized electron spin due to its coupling to the
lattice nuclear spin bath in a semiconductor quantum computer architecture. In the presence …

We present a detailed theoretical analysis of the electron spin decoherence in single
nitrogen-vacancy defects in ultrapure diamond. The electron spin decoherence is due to the …

We report a measurement of the spin-echo decay of a single electron spin confined in a
semiconductor quantum dot. When we tip the spin in the transverse plane via a magnetic …

We investigate pure dephasing decoherence (free induction decay and spin echo) of a spin
qubit interacting with a nuclear spin bath. While for infinite magnetic field B the only …

We investigate decoherence due to pure dephasing of a localized spin qubit interacting with
a nuclear spin bath. Although in the limit of a very large magnetic field the only decoherence …

We have evaluated hyperfine-induced electron spin dynamics for two electrons confined to a
double quantum dot. Our quantum solution accounts for decay of a singlet-triplet correlator …
