Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

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 ...

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 ...
