Spin-based quantum computing in silicon

This talk will review recent progress in the development of spin qubits in silicon. In particular it will consider qubit systems based on single phosphorus atoms, in which either the bound donor electron or the ³¹P nuclear spin can serve as a qubit, and also silicon metal-oxide-semiconductor (SiMOS) quantum dots within which single confined electrons can act as a qubit. In both cases the qubit control fidelity can be above above 99%, as required for some quantum error correction codes.
