Coherent control of single spins in diamond — •Fedor Jelezko and Jörg Wrachtrup — 3. Physikalisches Institut, Universität Stuttgart

Defects in diamond may have a large impact on solid state quantum physics in general and quantum information processing and communication in particular. This contribution will highlight recent results on the nitrogen-vacancy center (NV). Experiments on optical detection and manipulation of single electron spins will be reviewed. The experimental background of optical detection of single quantum systems in solids will be introduced. Well established single electron and nuclear spin measurement of NV defect is a key step in solid-state quantum information processing. Another important application of single spin manipulation is of more fundamental character. Experiments with single spins are suitable for experimental test of quantum mechanics. Projective measurements of single spins can be used as a test of the quantum Zeno effect and Bell's inequalities.
