Abstract

I will review recent experimental and theoretical progress in solid-state NMR computation performed at Stanford University. These have included: fabrication of ferromagnetic micro-magnets creating magnetic field-gradient as large as 10 Tesla / micron; observation of the long decoherence time (~ 25 sec) of nuclear spins in a silicon sample; and the nuclear polarization (~ 6%) by optical pumping via contact hyperfine interactions. These results, together with theoretical proposals on NMR pulse designs and naturally error-correcting implementations, make solid-state NMR a promising scheme for scalable quantum computation.
