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.
