Decoherence of the electron spin of NV-centers in Diamond — •Florian Rempp, Philipp Neumann, Torsten Gaebel, Fedor Jelezko, and Jörg Wrachtup — 3. Physikalisches Institut, Universität Stuttgart, Germany

Nitrogen-vacancy color centers (NV-center) in diamond with proximal C13 nuclear spins are one of the promising candidates for solid state quantum computers. One of the main assets of the NV-center is the optical accessibility of single spins while showing long T2 times due to low residual spin density.

We compute the decoherence the electron spin of NV-centers in diamond for various configurations of nitrogen and C13 atoms in the surroundings of the center. By characterising the effects of the those finite environments we hope to achieve better understanding of the experimental reality. It may thus be possible to estimate natural limits to the usage of NV-centers as quantum processors and memory.
