Silicon-based quantum computation

There is a worldwide race to build a computer which exploits the counterintuitive principles of quantum mechanics. Silicon is one of the most promising platforms for emerging quantum information technologies for two reasons: one, it possesses many of the key desirable criteria for low-error quantum information processing, and two, the microelectronics industry has decades of experience with producing ultrapure silicon and nanoscale silicon devices, which makes silicon-based quantum devices attractive for future commercial integration. This paper reviews a selection of silicon-based quantum computer design proposals, their technological requirements, and explores recent experimental progress towards their realisation.
