Coherent coupling between two single electron spins in diamond — •Torsten Gaebel, Michael Domhan, Philipp Neumann, Augusta Ene, Fedor Jelezko, Philippe Tamarat, and Jörg Wrachtrup — 3. Physikalisches Institut, Universität Stuttgart

Coherent control of single spins has attracted attention during last decade because of application in quantum information technology. We present recent progress on single spin magnetic resonance using single spins associated with defects in diamond. Optical readout of spin state allows achieving the ultimate sensitivity down to single electron spin level. Using novel implantation technique, single spin pairs consisting of nitrogen-vacancy and nitrogen defects have been created. Surprisingly, dipolar coupling, which is often considered as source of decoherence, do not shorten long phase memory time for two single coupled spins. Polarization transfer from optically pumped nitrogen-vacancy spn to nitrogen spin via cross-relaxation mechanism will be presented.
