University of Melbourne researchers invent new technique to make scalable Quantum Computers

The researchers have said that the new technique to engineer ultra-pure silicon makes it the perfect material to make quantum computers at scale and with high accuracy.

The University of Melbourne and the University of Manchester researchers have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.

“Fragile quantum coherence means computing errors build up rapidly. With robust coherence provided by our new technique, quantum computers could solve in hours or minutes some problems that would take conventional or ‘classical’ computers – even supercomputers – centuries,” said Project co-supervisor Professor David Jamieson.

Co-supervisor Professor Richard Curry of the University of Manchester said,"Ultra-pure silicon allowed construction of high-performance qubit devices – a critical component required to pave the way towards scalable quantum computers. What we’ve been able to do is effectively create a critical ‘brick’ needed to construct a silicon-based quantum computer. It’s a crucial step to making a technology that has the potential to be transformative for humankind.” 

"The largest existing quantum computers had more than 1000 qubits, but errors occurred within milliseconds due to lost coherence. Now that we can produce extremely pure silicon-28, our next step will be to demonstrate that we can sustain quantum coherence for many qubits simultaneously. A reliable quantum computer with just 30 qubits would exceed the power of today's supercomputers for some applications,” added Professor David Jamieson.

University of Melbourne alliance with Goulburn Murray Tertiary Education improve pathways for students in regional areas

The University of Melbourne, La Trobe University, GOTAFE, and Goulburn Murray Tertiary Education have joined forces to improve access and create greater participation for underrepresented students in the region.

The Goulburn Murray region, where all these universities are located hosts the largest Indigenous population and the largest multicultural community in regional Victoria.

Assistant Minister for Education Anthony Chisholm has congratulated the Goulburn Murray Tertiary Education on this partnership.

University of Melbourne Vice-Chancellor Professor Duncan Maskell said,"The quick work to find solutions to local education, training and workforce development challenges has spurred all the institutions involved and community into action."

“There is now a chance for the government to build on this solid base to elevate a thriving regional community by creating forums, events and information for families, young people and employers to understand workforce opportunities, ambitions and community-led research projects," added Professor Duncan Maskell.
