Abstract
Designer Molecules for Spin Quantum Computing
Wolfgang HARNEIT
Hahn-Meitner-Institut Berlin, Germany
The football-shaped C60-fullerene molecules are superb materials for nano-scale applications: They are only 1 nm in diameter, always
uniform in size and shape, and you can now simply buy them. You can place them on a surface (e.g. a silicon wafer), pick them up with a
scanning microscope tip, and arrange them in any pattern you like. You can also put an atom or molecule inside and use the fullerene as a
nano-container. In our group, we discovered that you can capture nitrogen atoms in the C60 ball. The 'endohedral' fullerene N@C60 has
an electron spin with a very long life time that could be used for spin quantum computing, as we presently investigate [1].
In my first lecture, I will talk about the fullerene molecules and illustrate their fascinating possibilities. A special emphasis will be
our N@C60 and P@C60 molecules and their unique spin properties. In my second lecture, I will give an introduction into quantum
computing. This will not be very theoretical, but rather focus on what the current experimental situation is. As the best results so far have
been obtained with nuclear spins ('liquid NMR'), this will be our main topic.
At the end, we can put everything together and you will chant with me:
Endohedral fullerenes are good for quantum computing! ;-)
