A solid-state implementation of a quantum computer composed entirely of silicon with no electrical gates or impurities was presented. Magnetic resonance force microscopy was used. Qubits are 29Si nuclear spins arranged as chains in a 28Si (spin-0) matrix. Optical pumping, algorithmic cooling, and pseudo-pure state techniques were used for the initialization.
