Towards two electronic spin entangelment — •Ingmar Jakobi, Florian Dolde, Boris Naydenov, Helmut Fedder, Fedor Jelezko, and Jörg Wrachtrup — 3 Physikalisches Institut and Research Center SCOPE, University of Stuttgart, Stuttgart 70659, Germany

The negatively charged Nitrogen-Vacancy center (NV) in diamond attracted a lot of interest lately due to the possibility of optical spin state read out of a single center and the possibility of coherent manipulations with microwaves at room temperature. Due to these unique properties the NV is an excellent candidate for room temperature quantum information processing. We conducted a systematic search with ground state depletion measurements (GSD) and double electron electron resonance experiments (DEER) on implanted samples in order to identify NV pairs with a suitable distance with a strong dipolar coupling allowing for entanglement experiments.
