Category Conferences - Seminars
Abstract: In this talk, Prof. Andrew Dzurak 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. He will 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 and nuclear spins. He will 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 the most recent assessments of silicon qubit fidelities. Andrew 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 prospects for operating silicon qubits at temperatures above 1K, which would open a path to the integration of conventional CMOS control electronics with the qubit system.

Biography: Andrew Dzurak is one of Australia’s leading experts in nanoelectronics and quantum computing technologies. He is the Director of ANFF-NSW, the NSW node of the Australian National Fabrication Facility (ANFF – see ), a network of university-based laboratories that provide researchers and industry with access to state-of-the-art fabrication facilities. ANFF enables users to process and transform materials into structures that have application in sensors, medical devices, nanophotonics and nanoelectronics.
Following a PhD at the University of Cambridge, Andrew returned to Australia in 1994 to establish Australia’s highest resolution electron-beam lithography capability at UNSW, offering nanoelectronic device feature sizes down to 10 nanometers.  He also began work on an initiative to construct in Australia a solid state quantum computer, and was one of the founder members of the Centre for Quantum Computer Technology in January 2000. The centre has achieved major advances in the international effort to realize large-scale quantum information processing and expanded in 2011 to become the ARC Centre of Excellence for Quantum Computation and Communication Technology. It maintains the world’s largest focused collaboration on silicon-based quantum computing and Andrew is the Centre’s Work-Package Leader in this area, as well as the Lead Investigator for a major grant from the US Army Research Office in silicon quantum computing.
Andrew and his team have developed a range of single atom nanotechnologies that will be required for silicon quantum computing and that also have relevance to today’s semiconductor industry. Andrew is a Director of the company Qucor Pty Ltd, which was established to commercialize this research. He is a regular invited speaker at international conferences on quantum computing and nanotechnology, and has served on numerous advisory bodies including the Expert Working Group for the 2012 Australian National Nanotechnology Strategy, for the Australian Academy of Science, the Expert Working Group for the DIISR 2008 Roadmap Review of the National Collaborative Research Infrastructure Strategy, and the Scholar Selection Committee of the Cambridge Australia Trust. In 2011 Andrew was elected to a UNSW Scientia Professorship, the highest academic rank within the university, for his research achievements.
Since 2010 Andrew has published 10 papers in the prestigious Science and Nature group journals, including 4 seminal papers in Nature that have demonstrated the world’s first one- and two-qubit quantum logic calculations in silicon chip devices. In total he has published well over 100 scientific papers and is a co-inventor on 11 patent families. In 2011 Andrew shared the Australian Eureka Prize for Scientific Research, and in 2012 was awarded the New South Wales Science and Engineering award for Excellence in Engineering and Information and Communications Technologies.
