✦ Synopsis

We have investigated the dynamics of the electron-nuclei coupled system in quantum dots. The bunching of results of the electron spin measurements and the revival in the conditional probabilities are salient features of the nuclear spin memory. The underlying mechanism is the squeezing of the nuclear spin state and the correlations between the successive electron spin measurements. A realization of the proposals for electron spins on single and double quantum dots is discussed.

We report low-temperature conductance measurements in the Coulomb blockade regime on two nominally identical tunnel-coupled quantum dots in parallel defined electrostatically in the two-dimensional electron gas of a GaAs/AlGaAs heterostructure. At low interdot tunnel coupling we find that the conduc

We theoretically discuss a quantum-dot quantum computer based on charged states. The tunneling Hamiltonian of a weakly coupled quantum-dot array in the Coulomb blockade region is shown to be reduced that of nuclear magnetic resonance spectroscopy. We numerically discuss the region in which this sche
