Congratulations, Dr. Abe! (and, Phosphorus in Silicon)

Eisuke Abe is now Doctor Abe. He defended his thesis, Pulsed Electron Spin Resonance in Phosphorus Doped Isotopically Controlled Silicon, yesterday.

Some of Eisuke's papers are on the arXiv or at the Itoh group home page. His thesis isn't available online yet, but the papers are of course relevant.

This work has implications for the coherence time of qubits done with phosphorus-doped silicon, as in the Kane scalable quantum computer. The Kane computer now has its own Wikipedia entry, which has a couple of things that aren't completely accurate, I think... only some isotopes of silicon, for example, have nuclear spin zero, which is in fact the point of Eisuke's thesis -- measuring the behavior with changing silicon isotopic composition.
