A solid-state quantum computer composed entirely of semiconductor silicon is proposed. Qubits are nuclear spins, I = 1/2, of 29Si stable isotopes in the form of atomic chains embedded in a nuclear-spin free matrix of 28Si stable isotopes. Each 29Si nuclear spin in a chain can be accessed selectively with a different resonant frequency (rf) due to a large magnetic field gradient created by a nearby micromagnet, i.e., unitary operations needed for quantum computing can be performed by fine tuning of the rf. Ensemble readout of qubits from 105 copies of the atomic chain is accomplished by magnetic resonance force microscopy.
