In the Back to the Future movies, the DeLorean car was able to travel through time thanks to a flux capacitor.

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.

A podcast on intuition: from how it works in the body, to how to harness it, and the story of two scientists who followed a hunch – about quantum biology.

We usually think of quantum entanglement in the realm of atomic systems, but now it's been scaled up to relatively massive objects. This opens the door to new kinds of technology.
Hawking had a cult-like following among academics and non-academics alike.
Stephen Hawking was a highly creative scientist, pushing past assumptions and playing with "what if" scenarios to take physics to new levels.
Physicist Michelle Simmons has won the 2018 Australian of the Year Award.
Australian of the Year Awards
Maths and science featured strongly in the 2018 Australian of the Year Awards. Along with physicist Michelle Simmons, maths teacher Eddie Woo and biologist Graham Farquhar were recognised.
How fast can quantum computing get? Research shows there’s a limit.
A future that continues to have increasingly fast computing depends on quantum physics – but research is showing that there are limits to how fast quantum computers can go.
What’s the link between technology and consciousness?
Researchers' views depend in part on what technology is (or will be) capable of – and in part on what consciousness actually is.
Looking inside a quantum computer.
As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.

Quantum computing is being described as "just around the corner". Is it?

Many scientists thought it was impossible, but one team has finally done it. They say operating their quantum computer is just like playing a game of Pacman.
The Micius satellite will encrypt data using fundamental laws of physics rather than crackable codes.
Things are kind of different on the quantum level.
Forget solid, liquid, gas. This research used advanced math to theorize about topological phases of matter. And over the years experiments with matter and cold atoms have been validating the ideas.

Much of the current research in quantum computing involves work at close to absolute zero. A simple breakthough with an everyday material could see them work at more acceptable temperatures.
Spin, liquid – just add quantum.
Here's how they could revolutionise science.
A simulated view of a black hole.
The information paradox is one of the great mysteries in our understanding of black holes. But has the famous theoretical physicist Stephen Hawking found the solution?
Quantum key distribution technology can be implemented with single photons using an optical channel to encrypt any data transmission.
There will be a quantum leap in securing online confidentiality with key distribution technology.
Binary systems are not enough if you want to improve security.
As hackers get more sophisticated in their cyber crime efforts we need to look to new technology to make our systems more secure, and potentially unhackable. So how can quantum physics help?
If kitty goes in, will she really be alive and dead?
It’s a century-old debate: what is the meaning of the wave function, the central object of quantum mechanics? Is Schrödinger’s cat really dead and alive? I was recently involved in an experiment conducted…
Harnessing the quantum property of light takes security to the next level.
Decades of data security research have brought us highly reliable, standardized tools for common tasks such as digital signatures and encryption. But hackers are constantly working to crack data security…
Many different worlds but a finite number.
Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? In a radical paper published…
