Australia took top billing at Quantum World Congress last month with Chief Scientist Dr Cathy Foley addressing a full plenary on quantum technology in the Indo-Pacific.

"You've probably seen quite a few Australians there at the Congress," said Cathy in her remarks. "That's a consequence of decades of patient investment in fundamental work and research."

Cathy spoke at a roundtable event alongside other scientific leaders from India, Japan, the United States, and Australia, the four 'Quad' nations, who have a semi-formal alliance for regional stability.

The speakers agreed that government support for quantum has to be broad, deep, and sustained if the technology is going to play its part in preserving a free and open Indo-Pacific.

"You can't turn away from quantum," said Cathy. "This isn't something you can dabble in. You've got to be all-in."
