The world’s first quantum logic gate in silicon has been demonstrated by Professor Andrew Dzurak and his research team at the University of New South Wales.
Reported in Nature (DOI: 10.1038/nature15263), each quantum bit (qubit) in this device is based on the spin state of a single electron, with microwave fields and applied voltages used for control and readout functions. The patented design is fully scaleable to multi-qubit devices and is compatible with materials and processes which are standard throughout the computer industry. Much of the device fabrication and process development work behind this breakthrough was conducted in the ANFF-NSW laboratories.

Recently published in Optics Letters (vol. 40, no. 17, p4154), the photonic filter developed by Alvaro and co-workers in the Centre for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS) delivers 6GHz frequency tuning with 48dB of notch suppression and a 3dB bandwidth of 98MHz. This work represents a key step towards a CMOS-compatible high resolution RF signal processor.
The devices reported in this paper were fabricated at IMEC in Belgium, with final etch steps performed at ANFF-NSW ahead of measurement in CUDOS laboratories at the University of Sydney.
All reports of research which has been enabled by ANFF-NSW should contain the following acknowledgement: ‘This work was performed in part at the NSW Node of the Australian National Fabrication Facility’. Each refereed journal publication containing an appropriate acknowledgement of ANFF-NSW is eligible for an ANFF-NSW Publication Award which comprises $500 worth of ANFF-NSW access.

Many of the devices Dane uses in his research pass through the ANFF-NSW laboratories for key fabrication steps en route to measurement laboratories within the UNSW School of Physics where Dane studies fundamental electronic phenomena. He aims to identify, characterise and control the many ways that electrons move and interact in electronic materials and devices. This allows him to determine what limits the efficiency of devices such as solar cells and light emitting diodes, and provides a roadmap for improving them. He also studies how electrons are influenced by their local environment, helping him to develop new types of devices (such as sensors) which will enhance future electronic products.
Dane’s research achievements and his commitment to communicating science have been recognised by his Young Tall Poppy award. Of the 13 prize-winners, Dane was honoured with the overall NSW title, and will spend the coming 12 months sharing his knowledge and enthusiasm for science with schools and community groups through the outreach program organised by the Australian Institute of Policy & Science.
