UNSW Sydney-led research paves the way for large silicon-based quantum processors for real-world manufacturing and application.
Australian researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology.
“Today’s publication in Nature shows our operations were 99 per cent error-free,” says Professor Andrea Morello of UNSW, who led the work, with partners in the US, Japan, Egypt, UTS and the University of Melbourne.
“When the errors are so rare, it becomes possible to detect them and correct them when they occur. This shows that it is possible to build quantum computers that have enough scale, and enough power, to handle meaningful computation.

An atomic array in silicon paves the way for large scale devices
A University of Melbourne led team have perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given us cheap and reliable conventional devices containing billions of transistors.
“We could ‘hear’ the electronic click as each atom dropped into one of 10,000 sites in our prototype device. Our vision is to use this technique to build a very, very large-scale quantum device,” says Professor David Jamieson of The University of Melbourne, lead author of the Advanced Materials paper describing the process.

A French-Australian collaboration is setting out to make silicon quantum computing a practical reality.
“I’m excited by our technology because it has the potential to change the world,” says Professor Andrew Dzurak of the University of New South Wales, the quantum computing expert who leads the Australian side of the partnership.
Andrew and his colleagues hope that their work will enable computing capabilities that are out of reach today and perhaps also result in the first universal quantum computer. Continue reading Quantum computing in silicon
High-power lasers have many potential applications: from medical imaging to manufacturing, shooting down drones or space junk, or powering deep space probes. But current laser technologies overheat at high power.
Associate Professor Rich Mildren and his team have developed a technique to make diamond lasers that, in theory, have extraordinary power range. Five years ago, their lasers were just a few watts in power. Now they’ve reached 400 watts, close to the limit for comparable conventional lasers.

The idea behind quantum computing has been around for almost half a century, but getting to a point where quantum effects can be created experimentally has taken a long time.
Now that materials physics and photonics have caught up, the race is on to devise and construct a quantum device that can out-compute today’s solid-state silicon supercomputers.
And Swinburne is leading the way with the use of photons.
