What is quantum entanglement? A physicist explains the science of Einstein’s ‘spooky action at a distance’

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.

Experiment shows Einstein’s quantum ‘spooky action’ approaches the human scale

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.

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.

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?
Harnessing the quantum property of light takes security to the next level. Boris Skoric

Quantum physics can fight fraud by making card verification unspoofable

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…
