N@C60 quantum bit engineering

We report on some engineering aspects in the context of utilizing N@C-60 molecules as quantum bits. Multi-step recycling HPLC leads to 100% pure material. Symmetry breaking environments provide full addressing of the high-dimensional Hilbert space. ATM-tip induced local anodic oxidation of silicon can be used for arrangements of fullerenes on surfaces. Finally, electrically detected magnetic resonance is capable of coherent manipulation and read-out of spin evolution of fullerenes at room temperature. (c) 2007 WILEY-VCH Verlag GmbH & Co.
