Abstract
Section titled āAbstractāInitializing a set of qubits to a given quantum state is a basic prerequisite\nfor the physical implementation of quantum-information protocols. Here, we\ndiscuss the polarization of the electronic and nuclear spin in a single\nnitrogen vacancy center in diamond. Our initialization scheme uses a sequence\nof laser, microwave and radio-frequency pulses, and we optimize the pumping\nparameters of the laser pulse. A rate equation model is formulated that\nexplains the effect of the laser pulse on the spin system. We have\nexperimentally determined the population of the relevant spin states as a\nfunction of the duration of the laser pulse by measuring Rabi oscillations and\nRamsey-type free-induction decays. The experimental data have been analyzed to\ndetermine the pumping rates of the rate equation model.\n
