A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Once described by Einstein as “spooky action at a distance,” quantum entanglement may now seem less intimidating in light of new research findings. Osaka Metropolitan University physicists have ...

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing travels faster than ...

Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that ...
