Quantum Computing – The Great Leap Forward

  • This event has passed.

The ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) in Australia has been working for over 20 years to develop quantum computing and communication devices and technology, using a national approach to study theoretical, experimental and practical ways to build a universal quantum computer, with the ambition of starting an Australian quantum computing industry. It has already successfully produced a number of spin-off enterprises.

The talk will focus on the work done at CQC2T’s UNSW group under the guidance of Prof Michelle Simmons, using spin electronics on a pair of single phosphorous atoms in Silicon, based upon the original qubit idea proposed by Dr Bruce Kane in 1998.

Dr. Otte Homan will present on how to manufacture and measure these qubit devices, and an outlook on building an Australian quantum computer.


Dr. Ir. Otte Homan

Dr. Ir. Otte Homan grew up in The Netherlands and studied applied physics at Groningen University. He graduated with an engineering degree with a thesis on quantised conductance in silicon MOSFETs in June 1992. He continued with a PhD research project in a combined position at the Paul Scherrer Institute and the Swiss Federal Institute of Technology in Zürich, Switzerland, under the supervision of Prof. Werner Bächtold and Prof. Bruce Patterson, developing a novel buried distributed Bragg reflection laser diode for metrology applications in GaAs/AlGaAs, completing the research with a PhD degree in Technical Sciences. From 1996 until 2002 he was a research group leader at the Electromagnetic Field Theory and Microwave Electronics group at ETHZ, leading the development and manufacturing of InP HEMT transistors for ultra-low noise and high-speed receivers for radio astronomy applications. Some of this work continues today with HEMT devices being manufactured for and used in ESO mm-wave receivers and on ESA’s Rosetta mission using ultra-low noise InP-HEMT based amplifiers in the Deep Space Network antennas.

From February 2002 until January 2012, in a team effort, he designed, built, and started the ETHZ FIRST-Lab, a large scale shared user facility for micro- and nanotechnologies, where he managed the front-end processing including lithography technologies and thin film etching and deposition technologies, as well as IT and Workplace Health and Safety. Starting with 6 professors and 35 students in 2002, this grew to around 25 professors and ~300 post-graduate and postdoctoral users in 2012. In January 2012 he moved to Sydney, joining Prof. Michelle Simmons at the ARC Centre of Excellence for Quantum Computation and Communication Technology at the University of NSW, as the Centre Laboratory Manager. Over the past decade, he has planned and built approx. 1500 m2 dedicated new laboratory space for ultra-high vacuum scanning tunnelling microscopes, dilution refrigerators and a fast turn-around cleanroom for micro- and nanofabrication.
