N2 - Our progress towards realization of the all-silicon solid-state NMR quantum computer [PRL, 89, 017901 (2002) and revised version] is reported. We show experimentally that the phase memory time TM (or phase decoherence time T2) of 29Si nuclear spins in single-crystal Si at room temperature can be extended up to 25 s (and possibly more) using RF decoupling techniques [quant-ph/0309164 (2003)]. A simple estimate shows that a T2 of 25 s will allow for 106 single-qubit and 10 4 two-qubit operations, by far the largest number of operations possible among existing solid-state quantum computer schemes. Recent progress in materials science needed for the realization of the all-silicon quantum computer is also discussed.
