The team of physicists at UNSW Sydney led by 2018 Australian of the Year Professor Michelle Simmons have built a super-fast version of the central building block of a quantum computer. The research is a milestone result of a vision first outlined by scientists 20 years ago.
UNSW engineers have created a new quantum bit that remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the number of calculations that could be performed in a future silicon quantum computer.
Australian researchers have figured out a way to deal with errors in quantum computers, giving them the essential architecture that may help this team become the first to build a functioning quantum computer in silicon.
Researchers at UNSW and the University of Melbourne have designed a 3D silicon chip architecture based on single atom quantum bits, providing a blueprint to build a large-scale quantum computer.
A dramatic increase in the amount of time that data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers, write Andrea Morello and Andrew Dzurak.
Two research teams working in the same UNSW laboratories have created quantum bits that offer parallel pathways for building quantum computers in silicon.
