Quantum scientists deliver world’s first integrated circuit at the atomic scale

On the other hand the Nature article and the research results are very interesting.

This has nothing to do with "quantum computers" or "integrated circuits".

The device is a special-purpose analog computer, which can simulate systems described by quantum mechanics, e.g. molecules, like the traditional analog computers, a.k.a. differential analyzers, which were used before WWII to simulate any systems that can be described by a system of differential equations.

However, for now, this isn't any kind of programmable computer.

To simulate another molecule, you have to build another analog computer, i.e. molecule simulator, with different spacings and sizes for the semiconductor quantum dots, though in the future they might achieve some degree of reconfigurability, to maybe simulate several kinds of molecules with a single quantum simulator.

It might not be a story of Australian expertise in (then) cutting edge technology that you like, but it's a real nugget of history.

His mentor was a New Zealander ... now a determinedly nuclear free country.

For example Canada built the NIRISS (exoplanet detection and analysis) and the FRS (guidance) devices for the JWST.
