Researchers at UNSW announce high-reliability silicon substrate qubit

[gary]

Researchers at Australia's most eminent and prestigious university, UNSW,
have announced they have developed a qubit from the nucleus of a phosphor atom
built into a silicon substrate which they claim matches the reliability of ion-trap
qubits.

Whereas the ion trap qubits required a vacuum, the researchers state that their
silicon-based technology will be far easier to scale up and manufacture, bringing
the prospect of a practical quantum computer that little bit closer.

They have published their results in Nature.

Them's fightin' words Gary. Our family has graduates from Macquarie, Sydney, UWS, UC and ANU. :D. Just one from Kensington Kindy.

A very nice piece of work. Semiconductors have been one of their strengths for a long time. The prospects are amazing. Let's hope we get a network to match.

Depending on who is doing the ranking UNSW comes in at 4 or 5 in Australia. eg

Of course if you said 'Australia's ugliest campus' you'd get fewer arguments.

Great stuff Andrew,

UNSW has some excellent post-graduate courses if the others
feel the urge to get up to scratch. :lol:
