Coherent Spin Manipulation in Diamond — •Eric Kessler, Géza Giedke, and Juan Ignacio Cirac — Max-Planck-Institut für Quantenoptik, Garching, Germany

Diamond, as a pure and clean material, seems to be an attractive playground for solid state quantum computation. For instance, the carbon nuclear spins display extremely long decoherence times even at room temperature due to their weak mutual interaction. On the other hand however, single nuclear spins are hardly addressable individually.

This drawback can be overcome by the use of intentionally implanted defects like the NV (Nitrogen-Vacancy) Center. Those impurities bring physical richness into the system and open the possibility of coherent manipulation of the nuclear spin system, as they both interact strongly with nuclear spins and are easily accessible via optical and microwave fields.

We present a method to simulate different classes of Hamiltonians in the nuclear Hilbert space using fast microwave and laser pulses resonant to the NV Center's transitions.
