Quantum speed limit may put brakes on quantum computers

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.

How quantum mechanics can change computing

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.

Antimatter breakthrough sheds light on matter’s shadowy twin

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.

Explainer: the mysterious missing magnetic monopole

Physicists have theorised about the existence of a magnetic monopole for decades, but we have yet to find one.

Electronics are getting small, and that is causing big problems

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.

Beating cyber criminals with quantum solutions

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?

Schrödinger’s cat gets a reality check

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…
