If an alien landed on Earth, how would you decide if it had free will like us, or was a sophisticated automaton?
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.
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.
‘Entangled’ beams successfully picked up at Earth.
The 'entangled' light particles spookily interact with each other at huge distances.
When black holes collide, gravitational waves are created in space itself (image is a computer simulation).
The SXS (Simulating eXtreme Spacetimes) Project
Einstein called entanglement "spooky action at a distance”. But now it's been used to design an incredibly sensitive detection method for gravitational waves.
There’s a lot we still don’t know about antimatter.
One of the great mysteries of the universe is why there is so much more matter than antimatter. Now a new experiment is helping us understand the nature of antimatter better than ever before.
Who knew the steam engine would prove so useful?
A new technique can remove noise from tiny electronic circuits, raising hopes of extremely efficient electronics and quantum technologies.
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.
All the magnets we’ve ever seen have a north and a south, but there might be some out there that have only one end.
Physicists have theorised about the existence of a magnetic monopole for decades, but we have yet to find one.
Spin, liquid – just add quantum.
Here's how they could revolutionise science.
The microprocessors on this wafer of silicon have transistors measuring in the nanometres.
As the components in electronic devices are shrinking to the nanoscale, even a single atom out of place can disrupt their function. But this also presents an opportunity to make them even better.
It’s proven: the universe is weird.
Testing the bizarre theory of quantum mechanics isn't easy, but scientists are making progress.
Measuring the photons in an entangled state was part of the experiment.
Scientists say they've have closed the loopholes on an experiment that tests a half-century old theory in quantum mechanics.So what does it reveal?
Scientists are searching for collisions between different ‘universe bubbles’ in the cosmic microwave background.
The idea that our universe is just one in a 'multiverse' of parallel universes is increasingly gathering attention from cosmologists. But can we ever test the theory?
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?
Current + lack of current = a headache for phycists.
We may have to rewrite physics textbooks after a material that can act both like a conductor and an insulator simultaneously has been discovered.
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?
Confused? You will be.
It's time we embraced quantum mechanics and stopped trying to explain away its weirdness.
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…
