We’ve designed a ‘flux capacitor’, but it won’t take us Back to the Future

Physicists have designed an electrical component that breaks time-reversal symmetry. Not quite the time machine from Hollywood but it should help with communication technology and quantum computing.

Error correcting the things that go wrong at the quantum computing scale

One of the challenges for quantum computing is knowing how to detect and correct errors that may occur in the data. And we can do that without even knowing what the data says.

A bit of numeracy can take the heat out of the asylum debate

What a Nobel prize-winning physicist can teach us about about trying to deal with the current global crisis over asylum seekers and refugees.
Supercomputers that can analyse major data sets will one day be superseded by quantum computing. AAP

Australian breakthrough brings quantum computing closer

Quantum computers that can solve complex problems in finance, health, security and defence are a step closer after a team of Australian and British researchers created the first working quantum bit based…
A simple desire to understand the way the world works has landed some Iranian researchers in hot water.

Particles and persecution: why we should care about Iranian physicists

On a given day, your typical physicist is mainly preoccupied with trying to understand the intimate secrets of the universe. As with most academics, we get to visit one another in parts of the world…
