Scaleable single-spin based quantum processor — •Michael Domhan, Torsten Gaebel, Iulian Popa, Achim Gruber, Fedor Jelezko, and Jörg Wrachtrup — Universität Stuttgart, 3. Physikalisches Institut, Pfaffenwaldring 57, 70550 Stuttgart

Readout and manipulation of the single spin states are crucial basics for spin-based quantum information processing. As formerly shown optically detected magnetic resonance (ODMR) techniques can be used to investigate single paramagnetic nitrogen-vacancy (N-V) defect centers in diamonds. As two-qubit operations on single NV-defect centers have also been performed, the effort will now be concentrated on coupling single spins between NV-centers. Potential scemes for scaling-up single-spin based quantum processor are presented.
