Where does Australia rank in research? And the Mythbusters are coming to Australia…

Australia has taken the podium alongside Japan and China as one of the top three science performers in a dynamic Asia-Pacific region. The Nature Publishing Index is a snapshot of the region’s scientific research in the past year based on publication output in Nature and the 17 Nature research journals.

And from chart topping to myth busting – the Mythbusters are coming to Australia during National Science Week.

Stories from the 2012 AIP Congress

New ideas on our energy future; hand-held cancer probes; ultra-powerful, high speed quantum computers;  and freeing up space on the mobile network.

These stories and more were presented at the national physics and optics conference, AIP/ACOFT 2012, at the University of New South Wales, Kensington.

Seeing stealth bombers and freeing mobile networks

A West Australian invention that’s keeping atomic clocks accurate, searching for gravity waves, and improving radar systems has won its creators a national physics prize.

And, as mobile networks become increasingly congested, Sydney engineers have designed new technology that can be retrofitted into mobile communication systems to increase their capacity and reduce the cost of mobile calls.

Read on for more stories from the final day of the national physics congress in Sydney.

Nobel laureate presents school science project

Posted on behalf of the University of New South Wales

It’s not every day that school students get to present their science project to a major scientific conference, and rarer still to receive a prize for it from a Nobel Laureate.

That’s the happy experience today for a team of four Year 11 students from Gosford High School, who have won a national competition conducted by UNSW and the Australian Institute of Physics.

How close are we to quantum computers?

Quantum computers promise ultra-powerful, high speed number crunching. They’ll help us to search vast databases and model biological molecules at an atomic level. They will crack the encryptions we rely on for banking and online security but also help us make new, unbreakable codes.

How close are we to building a quantum computer? Australian scientists are working on it.

Also at the national physics congress today: meet the man in charge of planning and designing the NBNdesigning a cheaper high-precision clock for GPS, astronomy and space tracking; and fighting greenhouse gases and arc-welding fumes with super-heated thermal plasma.

Accurate time with light and designing the NBN

A new, cheaper way to deliver accurate time across Australia: instead of using hydrogen maser clocks costing hundreds of thousands of dollars we can bounce signals through the national’s optical fibre network according to physics leaders speaking today and tomorrow.

Also today at the national physics congress in Sydney, meet the man whose job it is to figure out how to build the NBN.

And hear about the magic of thermal plasmas, from safer arc welding to saving the ozone layer.

Single-atom writer a landmark for quantum computing

Posted on behalf of the University of New South Wales

A research team led by Australian engineers has created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future.

In a landmark paper published today in the journal Nature, the team describes how it was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorus atom embedded in a silicon chip.

“For the first time, we have demonstrated the ability to represent and manipulate data on the spin to form a quantum bit, or ‘qubit’,  the basic unit of data for a quantum computer,” says Scientia Professor Andrew Dzurak. “This really is the key advance towards realising a silicon quantum computer based on single atoms.”
