Silicon-based quantum computing: The path from the laboratory to industrial manufacture
In this talk I will give an overview of the development of silicon-based quantum computing (QC), from the basic science through to its prospects for industrial-scale commercialization based on CMOS manufacturing. I begin with Kane’s original proposal  for a silicon quantum computer, conceived at UNSW in 1998, based on single donor atoms in silicon, and will review the first demonstrations of such qubits, using both electron spins [2,3] and nuclear spins . I then discuss the development of SiMOS quantum dot qubits, including the demonstration of single-electron occupancy , high-fidelity single-qubit gates , and the first demonstration of a two-qubit logic gate in silicon , together with assessments of silicon qubit fidelities [8,9]. I will also explore the technical issues related to scaling a silicon-CMOS based quantum processor  up to the millions of qubits that will be required for fault-tolerant QC, including the recent demonstration of silicon qubit operation above one kelvin .
