TITLE: Silicon-based quantum computing: The path from the laboratory to industrial manufacture
SESSION CHAIR: Professor Stephen Bartlett, University of Sydney, Australia
ABSTRACT:
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 [1] 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 [4]. I then discuss the development of SiMOS quantum dot qubits, including the demonstration of single-electron occupancy [5], high-fidelity single-qubit gates [6], and the first demonstration of a two-qubit logic gate in silicon [7], together with the most recent assessments of silicon qubit fidelities [9,10]. I will also explore the technical issues related to scaling a silicon-CMOS based quantum processor [8] 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 [11].
